Tonight I saw there was a new update to OMV (5.3.9-1 (Usul)) and I went ahead and updated it (I was on 5.x.x already before the update). Everything went fine and since I did this just after a new boot, my RAID1 wasn't mounted yet. I went to File Systems menu and noticed the raid file system status is not "Missing".
If I try to create a new file system I can pick the RAID1 but that will wipe all data on it which I can't afford to do. I also noticed it's now set to be coming from /dev/md127 instead of what it used to be /dev/disk/by-label/RAID1
Not too sure what to do at this point and any help would be appreciated.
For more info I also got 2 emails on this from OMV upon restart:
Here is the output from fdisk -l
and blkid /dev/md*
If you need to look at anything else please let me know.
