| 10:47 mikap | "Having stared and poked at FAIs new partition framework makes me consider partman as an alternative." -- http://schuldei.blogspot.com/2007/10/dear-lazyweb-au-pair-wanted.html - hm, what does he mean? :) |
| 10:49 stockholm | mikap: the control flow is not really designed to be capable of handlinge raid and lvm |
| 10:50 stockholm | mikap: preserve in this context makes only sense for partitions currently |
| 10:51 mikap | stockholm: ah ok |
| 10:51 stockholm | i tried to hack it into removing first and building new stuff then, but that is hard becuase of the control flow |
| 10:52 stockholm | or the lack thereof |
| 10:53 stockholm | all this is done beautifully in partman. it lacks an interface that fai can use |
| 10:54 stockholm | and it needs to be made non-interactive |
| 11:04 Mrfai | and partman must be independent of d-i. |
| 11:04 Mrfai | stockholm: but I do not understand what you mean by "control flow"? |
| 11:05 stockholm | Mrfai: it must have an interface that we can use |
| 11:05 stockholm | Mrfai: with controlflow i mean several things |
| 11:06 stockholm | the most obvious is that there is no seperation for tearing down and building up lvm, raid and partitions seperatily |
| 11:06 stockholm | it handles lvm, raid and partitoins in one go |
| 11:07 Mrfai | is the problem that the partition tool does all in one go, or the the description is in one file? |
| 11:07 Mrfai | s/the the/that the/ |
| 11:08 stockholm | that means it first removes partitions, creates new, THEN (after having broken its basis) removes raids, creates new ones, THEN (after hanving broken its basis) attempts to create, resize and/or delete lvm volumes |
| 11:08 stockholm | description in one file is no problem |
| 11:08 stockholm | the way the actual work takes place is bogous |
| 11:09 stockholm | (the -commands file) |
| 11:09 stockholm | there is a delicate interaction between partitions, raids and lvms on top |
| 11:10 Mrfai | ok. Would it help to add options, so it only does the raid or lvm thing or only the partition thing, or multiple things in one go? |
| 11:10 stockholm | it needs to get smarter to reorder things. |
| 11:11 stockholm | i tried to do that in a quick approach |
| 11:11 stockholm | but that failed because the teardown and buildup as it is now relies on the same data structures and changes them of course as it goes |
| 11:12 stockholm | my apprach was to have a "down" and "up" mode and permit only teardown commands in the "down" mode etc |
| 11:12 stockholm | but that fails obviously |
| 11:13 stockholm | "preserve" needs to be rethought, too. |
| 11:13 stockholm | as it makes most sense to preserve the *data*, not the partitions |
| 11:14 stockholm | it is possible to preserve all the data in lvms but change the partition layout |

| 11:14 MT | hi! |
| 11:15 stockholm | MT: http://paste.debian.net/40220 |
| 11:15 Mrfai | MT: http://paste.debian.net/40219, this is what happens in the last minutes |
| 11:15 stockholm | duh |
| 11:15 Mrfai | :-) |
| 11:15 stockholm | :-) |
| 11:16 Mrfai | stockholm: do we need to split preserve in preserve-data and preserve-partition? |
| 11:17 stockholm | Mrfai: we need to make it different things if lvm is involved at least |
| 11:17 stockholm | make it do |
| allee (~ach@dialin-212-144-130-252.pools.arcor-ip.net) left irc: Read error: No route to host |
| 11:18 stockholm | MT: i added a bit of what i have been thinking to the wiki |
| 11:18 stockholm | and filed a RFP for LINUX::Lvm |
| 11:19 stockholm | MT: it would be smart to re-implement the relevant partman bash stuff in perl for our purpose |
| 11:20 stockholm | MT: or write a parser and logger to partman in bash |
| 11:20 MT | which is the "relevant" partman part? |
| 11:20 MT | I guess partman does not have any sort of preserve/resize means, does it? |
| 11:20 stockholm | the logic for preserving, resizing, removing and creating of lvm, raid and plain partitions |
| 11:21 stockholm | it can resize everything that moves |
| 11:21 stockholm | or is on disk :-) |
| 11:21 stockholm | even advancd stuff with lvm and raid involved |
| 11:21 stockholm | or windows partitions i think |
| 11:21 stockholm | it can not sanely handle multiple disks yet |
| 11:22 stockholm | it only cares about the first disk at this point |
| 11:22 stockholm | MT: i think the parser in shdd2 is very good and exactly what we need |
| 11:23 stockholm | i have not seen much else besides -commands |
| 11:24 MT | I think that changing the sequence of commands shouldn't be all that hard |
| 11:24 MT | currently there is a single list FAI::commands |
| 11:25 stockholm | good |
| 11:25 MT | hmm, resolving dependencies between lvm and RAID might be an issue |
| 11:25 MT | but anyway |
| 11:25 MT | if we had two lists instead |
| 11:26 MT | the tear-down commands and the build-up |
| 11:26 stockholm | that would be a start |
| 11:27 stockholm | handling the tear down first, handling errors, starting build up based on that |
