Hi,
got a drive failure (bad block) during Raid5 grow (4x3TB -> 5x3TB).
Well... i don't have a backup file :/
Mdadm shows 1 drive as removed.
All 4 'good' drives are in the same reshape pos'n.
Any idea how to finish the reshape process? Or get the array back?
mdadm --stop /dev/md0
mdadm --assemble --force --verbose /dev/md0 /dev/sd[bcdf]
If that doesn't work, please show us the output.
You haven't (yet) lost your array. It's just degraded. You should
investigate why the one drive was kicked out of the array instead of
being rewritten properly (green drives?). In the meantime, assembly
with --force should give you access to the data to grab anything
critically important.
If you share the output of "smartctl -x /dev/sdX" for at least the
kicked drive, we can offer further advice.
Regards,
Phil
