I have 3 HDD's, each divided into 3 partitions.
I had created a RAID-1 for boot partition
- md0 created from sda0, sdb0
and had also created two RAID-5 arrays:
- md1 created from sda1, sdb1, sdc1
- md2 created from sda2, sdb2, sdc2
It used to work fine but one day I had to power off the machine (cold reboot) to get any response from the machine. After that, when the system started booting, it tried for a while to reconstruct the RAID arrays but after a few minutes it crashed silently.
I booted the system in linux rescue mode from the DVD and tried to re-assemble the RAID devices manually. I was able to re-assemble md0 and md1 using:
mdadm --assemble --scan /dev/md0
mdadm --assemble --scan /dev/md1
But when I try to re-assemble md2 using:
mdadm --assemble --scan /dev/md2
the system reboots silently again.
How can I fix this problem?
