I had rebooted my OMV, and was surprised to find my RAID devices gone. Fortunately using this command *seemed* like it restored the /dev/md4 target
But now I see a /dev/md4 showing in a clean state, and a /dev/md4p1 in a false state (see attachment). How do I clean this up? I can't tell if the Mirror is actually healthy or not. The 'mdadm --query --detail' and '/proc/mdstat' seems to report that it is.
I had another RAID device that was similar, and thought that since the one looked right, I could delete the /dev/md#p1 - not so! Doing that made both disappear
