Server refuses to boot when Raid5 disk is disconnected - /root/ missing
- by Ronni
I recently set up a NAS server running a Debian OS (6.0.4)
It contains 4 disks, 3 of them are in a Raid5 array, while the last one is used for the OS.
To simulate a disk-failure I unplugged one of the raid disks, which resulted in the OS being unable to boot.
It started the boot, recognized that md0 (the raid array) was running on 2/3 disks, and then threw a few errors.
It was unable to find the following directories:
/dev/root on /root,
/dev on /root/dev,
/sys on /root/sys,
/proc on /root/proc
It appears this happens regardless of which raid disk is removed. These directories are supposed to be on /dev/sdd my system disk.
Output from fstab and blkid :
