| 08:13 ritesh | Hi , all , i am trying to use FAI to make automatic installations for machines .At the moment i have made a custom file in disk_config/FAIBASE file , but it uses predefined size of the disk ( viz setting machines for 300GB or so), If i want to use dynamic allocation viz make settings so that FAI can automatically calculate disk space of machines be it 80GB |
| 08:13 ritesh | or 160 GB or 1 TB , automatically |
| 08:14 ritesh | can anyone guide me on creating partition.FAIBASE hook script to achieve disk independence |
| 08:15 Mrfai | you can use the class system and multiple disk_config files, or you can use a min and max for each size. E.g. 1G-30G |
| 08:17 ritesh | multiple disk_config files , is a problem , since there would be around 100 users , who will have various disk configurations |
| 08:20 ritesh | Can we write a partition.FAIBASE hooks file to create a dynamic file at run time , which creates a disk_config file with the correct table according to the specifications of the target system , after calculating disk space using fdisk on that partition |
| 08:21 ritesh | and then setup-storage can use that customized disk_config/FAIBASE file , to create the desired partition |
| 08:24 ritesh | there is a link where someone has used this idea to create dynamic file at runtime using python , and has also pasted the python script , but the solution is not working , can we create something of this sort in shell script of Perl |
| 08:24 ritesh | http://www.akasig.org/2007/02/09/how-to-install-dozens-of-custom-linux-boxes/ |
| 08:29 Mrfai | I think your main problem is to have 100 different disk configurations. You should try to lower this number. |
| 08:29 Mrfai | And try to use the min and max values in the disk_confiug files. |
| 09:20 ritesh | ok , let me put it this way , i want that the there should be only one grub entry at boot for fai , which automatically calculates disk space and creates 2 partitions ( 1 for /boot -500 MB , and rest for root / ) |
| 09:20 ritesh | is it possible ? |
| 09:20 ritesh | please advice |
| 09:24 Mrfai | primary /boot 10-500 ext4 rw,noatime,errors=remount-ro |
| 09:24 Mrfai | primary / 1- ext4 rw |
| 09:25 Mrfai | oops, I forgot the first line: disk_config disk1 fstabkey:uuid |
| 09:33 ritesh | My example disk_config file is of form |
| 09:33 ritesh | disk_config /dev/sda bootable:1 |
| 09:33 ritesh | primary /boot 500 ext4 rw,noatime,errors=remount-ro |
| 09:34 ritesh | primary - 20000 - - |
| 09:34 ritesh | disk_config lvm |
| 09:34 ritesh | vg my_vg sda2 |
| 09:34 ritesh | my_vg-swap swap 4096 swap sw |
| 09:34 ritesh | my_vg-root / 12000 ext4 errors=remount-ro |
| 09:35 ritesh | please advice how should i make changes |
| 10:32 ritesh | If anyone has a solution , please mail me at android.grove@gmail.com |
| 10:32 ritesh | thanks in advance |
