Greetings, Before taking chances on recovery I would like to gain better knowledge about what I Googled around for.
I have 4 SATA drives split between two different controllers with two
RAID5 partitions defined. My system froze and so a hard reset was done.
Both RAID5 groups md1 and md2 failed to assemble upon reboot. md0 is
RAID1 /boot. md1 is mounted as / and md2 is just data for what its worth.
Loading FC6 linux rescue what I see comparing md1 to md2 RAID5 groups is
very similar.
md1 - /dev/sda2 /dev/sdb2 indicate that of the four drives 0 is "removed"
and 1 is "faulty removed". 2 and 3 are "active sync".
/dev/sdc2 /dev/sdd2 indicate all four drives are "active sync".
md2 - /dev/sda5 /dev/sdb5 indicate that of the four drives 0 is "removed"
and 1 is "faulty removed". 2 and 3 are "active sync".
/dev/sdc5 /dev/sdd5 indicate all four drives are "active sync".
>From what I have read this is my best hope in recovering the raid groups.
mdadm -As --force --run /dev/md1 /dev/sd?2
mdadm -As --force --run /dev/md2 /dev/sd?5
Would this be about the safest thing to do to try and recover?
Any thoughts on this approach?
