I've no idea what happened, but the box I was working on last week has a *second* bad drive. Actually, I'm starting to wonder about that particulare hot-swap bay.
Anyway, mdadm --detail shows /dev/sdb1 remove. I've added /dev/sdi1... but see both /dev/sdh1 and /dev/sdi1 as spare, and have yet to find a reliable way to make either one active.
Actually, I would have expected the linux RAID to replace a failed one with a spare....
can you report your raid configuration like raid level and raid devices and the current status from /proc/mdstat?
Well, nope. I got to the point of rebooting the system (xfs had the RAID volume, and wouldn't let go; I also commented out the RAID volume.
It's RAID 5, /dev/sdb *also* appears to have died. If I do mdadm --assemble --force -v /dev/md0 /dev/sd[cefgdh]1 mdadm: looking for devices for /dev/md0 mdadm: /dev/sdc1 is identified as a member of /dev/md0, slot 0. mdadm: /dev/sdd1 is identified as a member of /dev/md0, slot -1. mdadm: /dev/sde1 is identified as a member of /dev/md0, slot 2. mdadm: /dev/sdf1 is identified as a member of /dev/md0, slot 3. mdadm: /dev/sdg1 is identified as a member of /dev/md0, slot 4. mdadm: /dev/sdh1 is identified as a member of /dev/md0, slot -1. mdadm: no uptodate device for slot 1 of /dev/md0 mdadm: added /dev/sde1 to /dev/md0 as 2 mdadm: added /dev/sdf1 to /dev/md0 as 3 mdadm: added /dev/sdg1 to /dev/md0 as 4 mdadm: no uptodate device for slot 5 of /dev/md0 mdadm: added /dev/sdd1 to /dev/md0 as -1 mdadm: added /dev/sdh1 to /dev/md0 as -1 mdadm: added /dev/sdc1 to /dev/md0 as 0 mdadm: /dev/md0 assembled from 4 drives and 2 spares - not enough to start the array.
--examine shows me /dev/sdd1 and /dev/sdh1, but that both are spares.
Hi Mark, please post the result from
cat /sys/block/md0/md/sync_action
There is none. There is no /dev/md0. mdadm refusees, saying that it's lost too many drives.
