Hello there,
In what seems to be my annual OMV disk-failure post: I am running a RAID 5 array across 6 discs (3 x 3TB Seagate and 3 x 4TB WD) and was alerted to a SMART error on one of the discs the other day (24 pending sectors on 1 of the 3TB Seagates). I bought and installed a new drive (4TB WD) to replace the disc with the error, and the rebuild has been running for the last day or so.
I received an email from OMV earlier this morning, stating that the rebuild had failed at 70.5% It appears that the spare disk in the array is now also exhibiting a SMART error (one of the other 3TB Seagates ... I've actually got 2 other new 4TB WD intended to replace the Seagates).
Have run the following commands from Putty this morning:
cat /proc/mdstat
Personalities : [raid6] [raid5] [raid4]
md127 : active raid5 sde[6](S) sda[7](F) sdf[8] sdd[11] sdc[9] sdb[10]
14651325440 blocks super 1.2 level 5, 512k chunk, algorithm 2 [6/4] [_UUUU _]

Is there any hope on being able to add back in the original disk and force a rebuild using mdadm --assemble, and then swap out the spare/failed disc and rebuild again?
Any other suggestions to try and salvage the array? I know I should have migrated from RAID 5 some time ago, and I probably won't get any sympathy in that respect, but would really appreciate any input in terms of next steps.
