RAID 5 not fault tolerant OMV 4.x (stable)
New
I have a RAID5 (5 disks) configured using the OMV GUI. I am running OMV 4.1.4-1.
Whilst working on the machine while shut down I accidentally unclipped one of the drives (SATA cable). I started the machine up and noticed that the RAID was not detected, and the file system on the RAID was listed as missing.
I found this post on the forum:
RAID Array missing after failed drive. Trying to rebuild
The above thread from post 10 pretty much describes my symptoms (except I have 5 disks) and I am (relatively) sure that the commands posted by ryecoaaron in post 11 will solve my problem. The question is, why does the RAID not start, but in a degraded mode, automatically, and the file system mounted? I could then add another disk, rebuild, and move on. Is there a way to tell OMV to start degraded RAIDs (so that they can be rebuilt)? Isn't that the purpose of RAID5 (to be fault tolerant if one disk is missing)?
