Dear all,
on boot, the system falls back into "INITRAMFS" , something to do with the
failed iscsi disks and if i don't type anything,a log starts showing containing
"SYNC_DISK..." among other things.. if i hit enter, it stops and i get back to
the INITRAMFS prompt.
support technicians in a remote collocated DC couldn't get my server back up
and running from a degraded raid so they plugged in a new drive and installed
debian over it (twice)
if they physically unplug all the old drives, the new debian installation boots
up normally.
i rebooted into a live cd and made sure that nothing in fstab points to the old
disks, though on boot i keep on seeing hdio_get_identity failed for
dev/sdXtiming outdropping to shell
and by X i mean all 10 drives.
after a lot of troubleshooting, i came across this interesting script
http://bootinfoscript.sourceforge.net/and after executing it on that server in
a ubuntu livecd i get very interesting details, this is the header though you
could find the full details in this pastebin url: http://pastebin.com/GLgUH7ig
