00:35 DavidDreezer	I came up with a workaround
00:35 DavidDreezer	if [ -s "$LOGDIR/additional.var" ]; then
00:35 DavidDreezer	. $LOGDIR/additional.var
00:35 DavidDreezer	fi
00:35 DavidDreezer	in the top of the 50 script
00:35 DavidDreezer	crude, but effective

13:25 alekibango	i tried daily squeeze iso and installed it on the raid created by fai. this workde well.... But i still fail installing FAI system using grub-pc on raid1 with fai 3.4.5 on squeeze...
13:32 mt	alekibango, could try manually executing grub commands to install it?
13:32 alekibango	i did once, but it failed to boot :)
13:33 alekibango	will try now again
13:33 mt	so just let it install and don't reboot at the end
13:33 mt	first see which errors are shown during execution of scripts
13:33 mt	and then let's do the manual tries
13:33 alekibango	mt: i already pasted those yesterday imho
13:33 alekibango	its 'unknown device'
13:34 alekibango	or somthing like that
13:34 mt	yes, ok
13:34 alekibango	http://pastebin.com/uW2dw195
13:34 mt	have you already got to the point that the install is complete (but probably broken)?
13:34 alekibango	you mean end of fai -- pres [enter] to reboot?
13:35 mt	yep
13:35 mt	but please don't reboot and get a shell instead
13:35 mt	I suppose chroot /target grub-mkdevicemap --no-floppy will work fine
13:36 mt	please paste /tmp/fai/disk_var.sh
Action: mt is hoping to finally have a confirmed-to-work solution for sw-raid+grub-pc

21:01 DavidDreezer	MT, are you there by chance?
21:01 mt	yes :-)
21:01 DavidDreezer	Good afternoon
21:02 DavidDreezer	it is afternoon there, no?
21:02 mt	well, for me it's rather evening (10pm)
21:02 DavidDreezer	oh, well, good evening then
21:02 DavidDreezer	thank you for the email that you sent to me, I appreciate it.
21:02 mt	you're welcome!
21:02 DavidDreezer	I got it working!
21:02 mt	sorry for leaving you all alone on this
21:03 mt	so how did you fix it?
21:03 DavidDreezer	I have an end to end trial run this afternoon
21:03 alekibango	mt i wrote some debian bug. about the grub
21:03 DavidDreezer	for today I put this in the head of the 50 script
21:03 DavidDreezer	if [ -s "$LOGDIR/additional.var" ]; then
21:03 DavidDreezer	. $LOGDIR/additional.var
21:03 DavidDreezer	fi
21:03 mt	ok
21:03 DavidDreezer	Ultimately, Micheal, I will merge my 45 and the 50 into on script
21:03 DavidDreezer	so they will be in the same shell
21:04 mt	but then, really, renaming the 45 script to 45-mac.source should do the trick
21:04 DavidDreezer	oh, you're right
21:04 mt	and merging will, of course, do as well :-)
21:04 mt	alekibango, which bug# is it?
21:04 alekibango	do not know yet :ú
21:04 DavidDreezer	I prefer to keep my modifications in a different script for future upgrade purposes, making it into a .source wouldbe excellent
21:05 alekibango	and i forgot to include some info... but the core is there
21:05 DavidDreezer	now, I have an end to end FAI install on software raid.
21:05 mt	I believe this should work like a charme, unless fai-class is buggy
21:05 mt	oh, software raid
21:05 mt	cool
21:05 mt	alekibango just had problems with his sw raid :-)
21:05 DavidDreezer	well, so I tried the 10-setup in ~45 as requested
21:06 DavidDreezer	and it did not work :(
21:06 DavidDreezer	there was no error logged
21:06 mt	yes, kind of expected
21:06 mt	alekibango and me debugged this all afternoon
21:06 DavidDreezer	however, upon booting the machine, error 15 then recovery prompt
21:06 DavidDreezer	ah!
21:06 mt	we believe to have found a working solution
21:06 mt	it would actually be great if you could try to confirm that
21:07 DavidDreezer	i substuted the 10-setup that I had posted and that worked, but of course that is not a scalable solution
21:07 DavidDreezer	i would love to
21:07 mt	alekibango, may I copy the link to the pastebin in here?
21:07 alekibango	y
21:07 mt	for the working 10-setup?
21:07 alekibango	np, dont ask all the time :) you are welcome
21:07 DavidDreezer	haha :)
21:08 mt	http://pastebin.com/4qQWGXec
21:08 mt	I believe it can actually be simplified
21:08 alekibango	DavidDreezer: he asked me like this 10 times today already :)
21:09 mt	bah, i've been fiddling with your system
21:09 DavidDreezer	i'm comparing that to mine Michael.
21:09 DavidDreezer	hmm
21:09 mt	you can, most probably, remove the mdraid
21:09 mt	an essential part is the sed line
21:09 alekibango	grub guys thought i should use grub from sources
21:09 alekibango	to test it
21:10 mt	omg
21:10 mt	ok, sure, that's kind of expected
21:10 alekibango	well, there was only 1 of them alive and he was not a grub devel
21:10 DavidDreezer	is grub-setup required?
21:10 alekibango	seems like weekend
21:11 mt	most probably it suffices if you put that on a running system, compile it, and run the grub-probe command to see what you get
21:11 mt	grub-setup?
21:11 alekibango	DavidDreezer: grub-install calls grub-setup
21:11 mt	thx
21:11 alekibango	if you use probes and grub setup you can avoid grub-install bugs
21:11 alekibango	:D
21:12 mt	who says that?
21:12 alekibango	well, just me, making fun a bit
21:12 alekibango	grub-install /dev/md0  should be the way to use it
21:12 mt	could easily be that this is true :-)
21:12 DavidDreezer	I also follow it with $ROOTCMD update-initramfs -k all -u      however I don't think it to be necessary
21:13 mt	not for grub, no
21:13 mt	but it might be necessary for other reasons
21:13 DavidDreezer	let me try this script, it only takes but a minute for me to copy/paste it into my server then reboot my client.
21:13 mt	if you get in trouble after grub has successfully loaded the kernel
21:14 alekibango	mt: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=606035
21:14 mt	the update-initramfs could be necessary if the new kernel was installed before mdadm was present, then the initrd lacks mdadm support and hence your system might fail
21:14 mt	but grub will work nicely without the update-initramfs
21:14 mt	cool, thx
21:15 DavidDreezer	ok, script installed, let me reboot my client and we shall see what we see.
21:15 alekibango	mt:  look near end
21:15 alekibango	heh i used czech locales, darn
21:16 mt	well, I guess people can translate that
21:17 mt	even though it might be nice to post a follow-up with that last bit translated
21:17 mt	it might be easier for grub-devs to grep through the code
21:17 mt	so actually grub-setup must be broken!?
21:17 mt	btw, could you also do a run using (md0) and post just the last bit
21:18 alekibango	mt:  its explained in text...
21:18 alekibango	that there is no /dev/md/0
21:18 mt	would that mean that (md0) is passed on to grub-setup?
21:18 alekibango	mt: no. (md/0) is passed
21:18 alekibango	and it doesnt work
21:18 alekibango	(md0) should be passed - works
21:18 mt	explained, yes, but the very precise wording helps so much when using grep
21:18 mt	:-)
21:19 alekibango	i believe debian should upgrade its bug reporting system
21:19 alekibango	launchpad is so cool compared to bug reporting in debian
21:20 alekibango	(still it sucks inside)
21:20 mt	really?
21:20 alekibango	well, installing it is pain
21:20 mt	I never quite got how to use launchpad
21:20 alekibango	it touches files all over the machine
21:20 mt	the debian BTS is so simple :-)
21:20 alekibango	mt: 1) i hate mails. i have almost 40k unread mails in my box
21:20 alekibango	2) i hate sending mails
21:21 DavidDreezer	OMG!
21:21 DavidDreezer	lol, 40k!
21:21 alekibango	and its all based on mails!
21:21 mt	ah, ok, so launchpad allows web bug filing?
21:21 alekibango	LD
21:21 alekibango	:))
21:21 alekibango	mt: right
21:21 mt	well, ok, so /me is just different
21:21 alekibango	i still read mails in mutt btw :)
21:21 mt	I strictly prefer email (as you already noticed...)
21:21 mt	so do I
21:22 alekibango	i hate even administering mail servers... :) its wrongly created service, should be memoryholed
21:23 DavidDreezer	I don't have the luxury of telling my customers "no email" :(
21:24 mt	for me, email mostly is a form of instant messaging
21:24 mt	alekibango, is grub-setup a script or compiled code?
21:25 alekibango	compiled
21:25 mt	ok, then I'll leave this to grub devs to debug :-)
21:26 DavidDreezer	ok, at faiend with this script, let me check for errors then reboot
21:26 mt	even though it would probably be considered a nice service to the grub-devs if you could indeed compile their latest version and probably just try calling grub-setup
21:26 mt	no need to install anything, just compile
21:26 alekibango	we can even do this in live system
21:26 DavidDreezer	this version errored
21:26 alekibango	if aufs will be able to keep it ok
21:26 alekibango	:D

21:27 mt	DavidDreezer, which version of grub are you using
21:27 DavidDreezer	grub2
21:27 mt	ah, you're running lenny
21:27 mt	is that right
21:27 mt	?
21:27 DavidDreezer	this server is open to the world, by the way, if you want access to it
21:27 mt	that would make the second one today :-)
21:28 alekibango	:)
21:28 alekibango	DavidDreezer: which grub2?
21:28 mt	well, maybe, yes
21:28 mt	got an IP for me?
21:28 alekibango	which version of grub-pc ?  last squeeze ?
21:28 DavidDreezer	our office is not, of course, but my house, i have opened so that I can reach it from the office
21:28 DavidDreezer	root@faiserver:/var/log/fai/db099.dh01.groupee-inc.net/last# dpkg --list | grep grub
21:28 DavidDreezer	ii  grub                              0.97-47lenny2              GRand Unified Bootloader (Legacy version)
21:28 DavidDreezer	ii  grub-common                       1.96+20080724-16           GRand Unified Bootloader, version 2 (common files)
21:28 alekibango	1.96+20080724-16 - this is somewhat old
21:29 alekibango	:)
21:29 mt	well, maybe it's not quite as broken as yours :-)
21:29 DavidDreezer	i did an apt-get update, upgrade yesterday
21:29 alekibango	is it lenny?
21:29 DavidDreezer	yes
21:29 alekibango	ah :) this script might need to have different solution for lenny
21:29 alekibango	:)
21:30 mt	I think all it takes should be dropping the mdraid
21:30 mt	DavidDreezer, could you just go into a console (instead of rebooting)
21:30 DavidDreezer	i'd been unable to get sw raid working under fai 3.x or old grub
21:30 DavidDreezer	certainly can
21:30 DavidDreezer	it is at a consoile now
21:30 mt	and type the commands one-by one
21:30 mt	so well,
21:30 mt	export ROOTCMD="chroot /target"
21:31 mt	so you can copy them off from the pastebin or from the script
21:31 mt	#
21:31 mt	$ROOTCMD grub-mkdevicemap --no-floppy
21:31 mt	well, I'll do the copying in here (with slight modifications)
21:32 mt	$ROOTCMD grub-probe -tdrive -d /dev/md0
21:32 DavidDreezer	so run first
21:32 DavidDreezer	$ROOTCMD grub-mkdevicemap --no-floppy
21:32 mt	(assuming that BOOT_DEVICE is /dev/md0)
21:32 DavidDreezer	yes?
21:32 mt	yes
21:32 DavidDreezer	it is
21:32 DavidDreezer	or should be
21:32 mt	cat /tmp/fai/disk_var.sh
21:32 mt	should tell
21:32 DavidDreezer	SWAPLIST=${SWAPLIST:-"/dev/md1"}
21:32 DavidDreezer	BOOT_DEVICE=${BOOT_DEVICE:-"/dev/md0"}
21:32 DavidDreezer	ROOT_PARTITION=${ROOT_PARTITION:-/dev/md2}
21:33 mt	should be fine
21:33 mt	what does grub-probe say?
21:33 DavidDreezer	when i ran ROOTCMD grub-mkdevicemap no-floppy i got the prompt, with no response of any kind
21:33 DavidDreezer	just back to prompt
21:33 mt	that's fine
21:34 mt	no news is good news :-)
21:34 mt	but grub-probe should give some news :-)
21:34 DavidDreezer	db099:~# $ROOTCMD grub-probe -tdrive -d /dev/md0
21:34 DavidDreezer	(md0)
21:34 DavidDreezer	db099:~#
21:34 DavidDreezer	which is correct, no?
21:35 mt	alekibango, this "old" version is much better than yours :-)
21:35 mt	yes, that's great
21:35 mt	$ROOTCMD grub-install --no-floppy --modules="lvm raid" "(md0)"
21:35 mt	would be the next step
21:35 DavidDreezer	oh, wait though
21:36 mt	?
21:36 DavidDreezer	this is the script
21:36 DavidDreezer	$ROOTCMD grub-install --no-floppy --modules="lvm raid mdraid" "$GROOT"
21:36 DavidDreezer	and the error was could not find module mdraid
21:36 mt	yes, but I believe mdraid isn't necessary
21:36 mt	so use the above command
21:36 DavidDreezer	shell.log:grub-mkimage: error: cannot stat /usr/lib/grub/i386-pc/mdraid.mod
21:37 mt	without mdraid
21:37 DavidDreezer	i think you're right
21:37 DavidDreezer	it appears to have been successful
21:37 DavidDreezer	db099:~# $ROOTCMD grub-install --no-floppy --modules="lvm raid" "(md0)"
21:37 DavidDreezer	Installation finished. No error reported.
21:37 DavidDreezer	This is the contents of the device map /boot/grub/device.map.
21:37 DavidDreezer	Check if this is correct or not. If any of the lines is incorrect,
21:37 DavidDreezer	fix it and re-run the script `grub-install'.
21:37 DavidDreezer	(hd0)/dev/hda
21:37 DavidDreezer	(hd1)/dev/hdb
21:37 mt	sounds good
21:38 DavidDreezer	shall I try to reboot?
21:38 mt	nope
21:38 mt	$ROOTCMD update-grub
21:38 DavidDreezer	oops
21:38 mt	you already did?
21:38 DavidDreezer	no
21:38 mt	ok :-)
21:38 DavidDreezer	oops as in "i forgot that step"
21:38 mt	it wouldn't have been too bad
21:38 DavidDreezer	success
21:38 DavidDreezer	db099:~# $ROOTCMD update-grub
21:38 DavidDreezer	Updating /boot/grub/grub.cfg ...
21:38 DavidDreezer	Found linux image: /boot/vmlinuz-2.6.26-2-686-bigmem

21:38 DavidDreezer	Found memtest86+ image: /boot/memtest86+.bin
21:38 DavidDreezer	done
21:38 mt	just no menu of any kind
21:39 mt	well, then please give it a try ...
21:39 DavidDreezer	will do, cross fingers
21:39 mt	with alekibango we afterwards even verified that corrupting either of the two disks still left the system in a bootable state
21:41 DavidDreezer	grub rescue mode.  :(
21:41 DavidDreezer	is this due to my partition topography?
21:42 mt	hmm
21:43 mt	can you do "ls"
21:44 DavidDreezer	yes, i have to bring my laptop down to where i have the computer physically. I might disconnect momentarily
21:44 mt	I'll learn about rescue mode meanwhile
21:45 DavidDreezer	ls works. i have all the hd0 and 1 partitions. no md of course
21:46 mt	grub manual says
21:47 mt	cat /grub/grub.cfg
21:47 DavidDreezer	no such disc
21:48 mt	type "help"
21:48 mt	is there something about "root"
21:48 DavidDreezer	makes some sense.  grub is on md0, and we have no md0 yet, no?
21:48 mt	I believe it *should* have mapped that
21:48 DavidDreezer	i can try root (hd0,1)
21:48 mt	but that might be a wrong assumption
21:48 mt	pls do
Action: mt thinks he might understand
21:49 DavidDreezer	dine.  (hd0,1): Filesystem is ext2
21:49 DavidDreezer	now i need a boot line, i htink
21:50 mt	how long does a reinstall take?
21:51 DavidDreezer	5 minutes
21:51 alekibango	my takes some 300 seconds
21:51 DavidDreezer	I can do them all day
21:51 mt	might be the quicker option then :-)
21:51 DavidDreezer	works for me
21:51 mt	so what am I after:
21:52 mt	grub-pc in lenny seems not to have properly working support for raid
21:52 mt	so must be installed in each device separately
21:53 mt	grub-install line must be run with /dev/hda1, /dev/hdb1
21:53 mt	(two times)
21:53 DavidDreezer	well, but this works:
21:53 DavidDreezer	$ROOTCMD /usr/bin/grub-mkimage --output=/boot/grub/core.img ext2 pc biosdisk raid
21:53 DavidDreezer	$ROOTCMD /usr/sbin/grub-install '(md0)'
21:53 DavidDreezer	$ROOTCMD /usr/sbin/grub-setup '(md0)'
21:53 DavidDreezer	$ROOTCMD /usr/sbin/update-grub
21:53 DavidDreezer	$ROOTCMD update-initramfs -k all -u
21:53 DavidDreezer	though it is not to the device
21:54 DavidDreezer	i've not got it to work installing to the device
21:54 mt	hmm
21:54 DavidDreezer	i've tried a for look installing to each device in device map
21:54 DavidDreezer	always gives an error 15 and rescue boot
21:54 DavidDreezer	loop*
21:54 mt	meaning this fully works including a booting system?
21:55 DavidDreezer	oh yes
21:55 DavidDreezer	remember I said wit went end to end this morning?
21:55 DavidDreezer	that was with the script i just quoted
21:55 DavidDreezer	however!
21:55 DavidDreezer	I have not tested pulling one drive to see what it does
21:55 DavidDreezer	but with both drives it boots perfectky
21:56 mt	well, I suppose it will work just fine then
21:56 mt	ok, could we try the following:
21:56 DavidDreezer	i would think because mdo is both drives
21:56 DavidDreezer	both or either,
21:56 mt	do you have a script that executes the above commands?
21:56 mt	(as part of your install)
21:56 DavidDreezer	yes, I do
21:57 DavidDreezer	want me to paste it for you?
21:57 mt	no, it's fine
21:57 mt	could you comment out the mkimage and grub-setup lines?
21:57 mt	and see whether it still workds?
21:57 mt	sorry, no, won't
21:57 DavidDreezer	my 10-setup has a case switch for HW_RAID or SW_RAID, then run the above commands for SW
21:58 mt	pls add --modules="lvm raid" to the grub-install line
21:58 DavidDreezer	for HW your default script works perfectly
21:58 mt	meaning we only run grub-install and update-grub
siggg (~jean@tra78-5-88-172-128-32.fbx.proxad.net) left irc: Ping timeout: 480 seconds
21:59 mt	maybe it's just that grub-mkimage must be told about the modules
21:59 DavidDreezer	ok, this is where I am
21:59 mt	which won't happen if run as I told you before
21:59 DavidDreezer	$ROOTCMD /usr/bin/grub-mkimage --output=/boot/grub/core.img ext2 pc biosdisk raid
21:59 DavidDreezer	$ROOTCMD /usr/sbin/grub-install --modules="lvm raid" '(md0)'
21:59 DavidDreezer	$ROOTCMD /usr/sbin/grub-setup '(md0)'
21:59 DavidDreezer	$ROOTCMD /usr/sbin/update-grub
21:59 DavidDreezer	$ROOTCMD update-initramfs -k all -u
21:59 DavidDreezer	now you want me to remove which part?
21:59 mt	just comment out, don't remove :-)
21:59 DavidDreezer	ok
21:59 mt	grub-mkimage and grub-setup lines
21:59 DavidDreezer	ok, just a sec
22:00 mt	both of which should be called by grub-install anyway
22:00 DavidDreezer	now, it is hard coded to md0. do you want to make a change to that as of yet?
22:01 mt	we'll leave this for a second round :-)
22:01 DavidDreezer	very well, let me place this and reboot the client
22:08 DavidDreezer	< wish list: someday faimond will timestamp entries
22:08 DavidDreezer	:)
22:10 mt	faimond has the optopn -T which add a timestamp to the log.
22:10 mt	(quoting Mrfai)
22:11 mt	from http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=290539
22:12 DavidDreezer	oh my so it does!
22:12 DavidDreezer	ok, faiend
22:12 DavidDreezer	let's see
22:12 mt	any errors?
22:12 DavidDreezer	yes
22:12 DavidDreezer	fai.log:GRUB_PC/10-setup.test FAILED with exit code 1.
22:12 DavidDreezer	shell.log:grub-mkimage: error: cannot stat /usr/lib/grub/i386-pc/mdraid.mod
22:12 DavidDreezer	shell.log:++ error=1
22:13 mt	mind pasting 10-setup.test?
22:13 DavidDreezer	.test?
22:13 mt	that's what you quoted
22:13 DavidDreezer	it is, and yet
22:14 DavidDreezer	there is none
22:14 mt	damn sure?
22:14 DavidDreezer	oh my gosh I see
22:15 DavidDreezer	I moved the test script we ran earlier to test, but left it executable
22:15 DavidDreezer	which of course, it did
22:15 DavidDreezer	I'm an idiot
22:15 mt	no, surely not
22:16 mt	it might just mean that things have to be restarted
22:16 mt	either of the scripts might have left something semi-broken behind
22:16 DavidDreezer	well, the actual 10 setup that we want to try did not error
22:16 DavidDreezer	it was the previous iteration that errored
22:17 DavidDreezer	as expected
22:17 DavidDreezer	so I chmod -x that
22:17 DavidDreezer	and shall reboot yet again. sorry for wasting your time
22:17 mt	oh, np, I just keep doing other things meanwhile
22:27 DavidDreezer	no errors, now let me go see if it boots
22:30 DavidDreezer	alas.   error: no such disk, then rescue mode. doing an LS shows only the hd0 and1
22:32 mt	hmm
22:32 mt	so let's see what has to be added back
22:32 mt	maybe try the mkimage first
22:33 DavidDreezer	does grub-install call grub-setup?
22:33 mt	yes, at least it's supposed to :-)
22:34 DavidDreezer	ok, let me uncomment the mkimage and go from there
22:35 mt	btw, you might want to do an explicit ping to make me respond faster, I'm usually acting on other desktops
22:36 DavidDreezer	ok, i'm in no hurry, it is Sunday and I feel guilty as though I am taking advantage of your time.
22:46 DavidDreezer	same problem, so I shall try it without mkimage but with grub-setup
22:47 mt	ok
22:47 DavidDreezer	I think this will work
22:47 mt	this would make a debuggable case
22:47 DavidDreezer	my script line is this
22:47 DavidDreezer	$ROOTCMD /usr/sbin/grub-setup '(md0)'
22:48 mt	because grub-install is a script
22:48 DavidDreezer	and it will work, I thinkj, because I am telling it mdo
22:48 DavidDreezer	md0*
22:48 DavidDreezer	ratehr than letting it decide by itself
22:48 mt	but grub-install should be doing just that, call grub-setup with md0 as argument
22:49 mt	*if* it works, another run with grub-install --debug would be nice
22:49 DavidDreezer	if it doesn't work then I blame martians or other space aleins
22:54 mt	well, if it doesn't, we should still be able to make one single script out this, working for sw and hw raid
22:54 mt	by the simple means of grub-probe
22:55 mt	where "doesn't work" means "it only works if both the grub-mkimage and grub-setup calls are in there"
22:56 DavidDreezer	i don't see a /usr/sbin/grub-setup in my nfsroot
22:57 DavidDreezer	so, it is run on the client after grub is installed? so I should see it on the client in /target/susr/sbin, correct?
22:57 DavidDreezer	ah yes
22:58 DavidDreezer	and it is a binary
23:00 mt	yes, right
23:00 DavidDreezer	grub recovery.
23:00 mt	grr
23:00 DavidDreezer	i shall uncomment both lines, and add -v to setup
23:00 DavidDreezer	or wa sit to install?
23:01 mt	--debug to install
23:01 DavidDreezer	ok, debug to install
23:01 mt	but if you got time, maybe first try without --debug
23:01 DavidDreezer	sure
23:01 mt	just to see it really works
23:01 DavidDreezer	it has worked twice today
23:01 mt	(I know, it did before, but it never did afterwards)
23:01 DavidDreezer	third time should be no different
23:01 mt	fingers crossed
23:02 DavidDreezer	we ar enow back where we started
23:02 DavidDreezer	$ROOTCMD /usr/bin/grub-mkimage --output=/boot/grub/core.img ext2 pc biosdisk raid
23:02 DavidDreezer	$ROOTCMD /usr/sbin/grub-install --modules="lvm raid" '(md0)'
23:02 DavidDreezer	$ROOTCMD /usr/sbin/grub-setup '(md0)'
23:02 DavidDreezer	$ROOTCMD /usr/sbin/update-grub
23:02 DavidDreezer	$ROOTCMD update-initramfs -k all -u
23:02 DavidDreezer	i'll go hit reset
23:15 DavidDreezer	Failed. I'm speechless. this has worked twice today and we have done nothing other than edit this script today. This makes no sense.
23:15 mt	the --modules is new in there ...
23:16 DavidDreezer	oh good point
23:16 DavidDreezer	but what would that do to cause grub to not locate the conf file
23:17 mt	no ideas
23:17 DavidDreezer	just to be sure let me grab my original copy of this file
23:18 DavidDreezer	just confirmed, you are correct
23:34 DavidDreezer	ok, I have removed the modules and am back to where we started. it boots fine. normally, into a working OS
23:36 mt	so could you now remove the grub-setup line?
23:36 mt	if that keeps working
23:37 mt	I think we will always need the grub-mkimage line if --modules doesn't work for you
23:37 mt	but then it would be interesting to get two logs
23:37 mt	grub-install --debug with and without --modules
23:37 mt	and then compare the diff ...
23:38 mt	do you think you could generate those two logs?
23:38 mt	I'll probably get to bed soon, but if you could generate those two logs and send them via email that would be fantastic
23:39 mt	that debugging step is one thing
23:39 mt	the other one is making a nice script for you
alleehol (~quassel@allee.mpe.mpg.de) joined #fai.
23:39 mt	I think if you include the grub-probe step you should be able to get away with a single piece of code for both hw and sw raid
23:40 DavidDreezer	oddly, on first boot it always tells me that my last mount time was in the future, but that is relatively a minor issue.
allee (~quassel@allee.mpe.mpg.de) left irc: Read error: Connection reset by peer
23:40 mt	probably some system time is wrong
23:41 mt	maybe hw clock being using during install and ntp later on?
23:42 DavidDreezer	possible
23:42 DavidDreezer	the first script i have in class is an ntp script. wierd
23:42 DavidDreezer	remove the entire grub-setup line
23:42 DavidDreezer	ok
23:43 DavidDreezer	i'll generate both logs, tar them and email them to you
23:43 mt	cool, thanks!
23:43 DavidDreezer	thank you for all of your help with this
23:43 mt	well, thanks for testing&debugging, I'm kind of doing all this theoretically only :-)
23:43 DavidDreezer	it is my hope that we come out of this with a single script that we can give to everyody
23:44 mt	haven't got a single system running grub-pc as of yet
23:44 mt	yep, indeed
23:44 DavidDreezer	well, mine works, however it is hard coded to do so
23:44 mt	although it seems that lenny and squeeze might need different treatment
23:44 DavidDreezer	now we just need ot reach it so that it is programatic
23:44 alekibango	it would rock when it could work on all debian, maybe even ubuntu versions :)
23:45 mt	could you paste your current script?
23:45 DavidDreezer	we can add in a uname switch, i guess. kind of as kludge though
23:45 DavidDreezer	current, sure
23:45 mt	so I can meanwhile hack that to what I think should work for both sw and hw raid?
23:45 alekibango	mt you deserve an award for your help today :)
23:45 mt	even though it might still have all these grub-setup, grub-mkimage lines
23:46 DavidDreezer	http://paste.debian.net/101606/
23:46 DavidDreezer	now to be clear
23:47 mt	oh no, I'm just trying to get rid of one of the longest outstanding issues
23:47 mt	this grub-pc setup is causing pains for ages now
23:47 DavidDreezer	for the next steps
23:47 DavidDreezer	you want to remove
23:47 DavidDreezer	grub setup
23:47 DavidDreezer	then test with and without debug for install
23:47 DavidDreezer	correct?
23:49 DavidDreezer	oh, no. it's install debug with and without modules
23:50 mt	alekibango, will you be available for a few more minutes?
23:50 alekibango	ok whats up
23:50 alekibango	i will be here whole night imho
23:51 mt	DavidDreezer, yes grub-install with and without --debug
23:51 mt	argh
23:51 mt	dam
23:51 mt	grub-install --debug with and without --modules
23:51 mt	alekibango, I'll try to hack DavidDreezer's script and wanted to ask whether you could give that one a try as well
23:51 DavidDreezer	ok, i am running it now as is, without the setup line
23:52 alekibango	mt: no problem, will try
23:52 mt	maybe we can come up with a script which works both in lenny and squeeze
23:52 DavidDreezer	if that passes i'll then run install with and withoug modules, both debug
23:52 alekibango	mt ic
23:55 mt	it's http://paste.debian.net/101608
23:56 mt	alekibango, if you could give that one a try it would be great
23:56 mt	if it works, we could even try to further simplify it
23:56 alekibango	lol you sound like the guy in the movie... officespace
23:57 mt	DavidDreezer, this should also work for you, both for hw and sw raid (because of grub-probe magic)
23:57 mt	huh, what's that movie about?
23:57 alekibango	lol you have to see it sometimes
23:57 DavidDreezer	is squeeze escaping the partition number or sometning odd?
23:57 DavidDreezer	(hence the sed line)
23:58 mt	squeeze munges /dev/md0 into (md/0)
23:58 DavidDreezer	ugh
23:58 mt	but only (md0) works
23:58 DavidDreezer	badbad bug
23:58 mt	well, /dev/md/0 does exist on some systems, don't really know when it is just /dev/md0 and when it is /dev/md/0
