Hello,
I'm new here and likely don't understand the etiquette. Please be
patient with me.
I have two raid 5 arrays connected through an LSI 9601-16e (SAS2116)
card. I also have a few other single drives connected to the SAS card.
I was mounting both arrays through fstab using the original UUIDs of
the arrays. The system had been working great, remounting both arrays
on boot, etc. until yesterday when I shut the system off to remove one
of the single drives.
I didn't touch the raid array drives at all, but when I rebooted the
system, neither raid array mounted successfully. When I checked their
status, I noticed both arrays had changed to "inactive", and further
investigation showed that the UUIDs of both arrays had changed.
I started investigating using the troubleshooting page of the Linux
raid wiki. I tried to reassemble (no --force however) but it wasn't
successful. Here is a summary of what I noticed:
Smart data seems OK for all drives.I found some reports of bad blocks,
non-identical event counts, and some missing array members.
md0 consists of 4x 8TB drives:
role drive events state
0 sdc 10080 A.AA (bad blocks reported on this drive)
1 sdd 10070 AAAA
2 sde 10070 AAAA
3 sdf 10080 A.AA (bad blocks reported on this drive)
md1 consists of 4x 4TB drives:
role drive events state
0 sdj 5948 AAAA
1 sdk 38643 .AAA
2 sdl 38643 .AAA
3 sdm 38643 .AAA
These are the things that stand out to me, but there may be other
issues I've overlooked. I have included the full output of the
troubleshooting commands below. I don't understand why the UUIDs would
have changed, but even after mkconf created a new mdadm.conf file, the
arrays would not assemble or mount. And I don't know how to fix the
situation without losing data. Please let me know how to proceed.
Thanks,
Bill
