i was playing with mdadm command to learn setting up raid on linux so i did this
i setted up a raid 5 on vmware (virtual Debian 6 )with 3 disks /dev/sdb /dev/sdc /dev/sdd
and it was working fine . then i ran these 2 commands to see what happens
mdadm /dev/md0 --fail /dev/sdb
mdadm /dev/md0 --fail /dev/sdc
after that i restarted the virtual machine.
and when the system booted there was no raid like there wasn't any raid .
so i was thinking is it possible to recover the raid since there wasn't a real failure .
