I recently set up a
NAS server running a
Debian OS (6.0.4)
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.
If you need additional info, please let me know.
