I refactored the setup_harddisks script that came with FAI to do this sort of thing, however it needs testing and success/failure reports to become part of FAI. The script, currently up on my web shite at: http://vilain.net/linux/fai/ Would allow you to set up a raid configuration using this disk_config file (you need to install raidtools2 and probably lvm10 into the FAI nfsroot for the script to work): # disk configuration for a 2 disk IDE configuration with RAID 1 # (mirroring) # <type> <mountpoint> <size in mb> [mount options] [;extra options] disk_config hda primary / 256 rw,errors=remount-ro ; raid(1,md0) primary swap 1024 rw ; raid(1,md1) logical /usr 2048 rw,notail ; raid(1,md2) reiser logical /var 600 rw,notail ; raid(1,md3) reiser logical /home 0- rw ; raid(1,md4) reiser disk_config hdc primary - 256 ; raid(1,md0) primary - 1024 ; raid(1,md1) logical - 2048 ; raid(1,md2) logical - 600 ; raid(1,md3) logical - 0- ; raid(1,md4) -- Sam Vilain, [EMAIL PROTECTED] "Assuming that either the left wing or the right wing gained control of the country, it would probably fly around in circles" - Pat Paulsen -
