If a RAID and LVM system results not bootable anymore the following steps can be used to diagnose the problem:
Boot with Debian "Woody" 3.0 cdrom with bf24 kernel.
Exit to a shell and load the extension disk.
extdisk |
Manually start raid arrays with:
raidstart /dev/md1 |
repeat this for all raid arrays.
Look for error messages during raid arrays start. Look at /proc/mdstat for array status.
Start LVM subsystem with:
vgscan |
Activate volume groups with:
vgchange -a y vg00 |
repeat this for all volume groups.
Check file systems:
fsck /dev/vg00/root |
repeat this for all logical volumes with a file system inside.
Mount file systems over /target
chroot into /target
