I have an R410 and created a RAID 6 with 4 disks. I cloned an R310 server's boot USB device and fired up the R410. I changed its hostname and IP, configured Plex, setup an rsync process to sync the r410 with the r310. All seemed well. I powered down the r410 and a decided it was time to rsync because I have additional media to sync.
After powering up, my filesystem says status "missing".
blkid on the r410 says:

Now, the r410 used to reference drives in the nomenclature the r310 did. The RAID setup is different between the two. R310 uses a RAID config created in OMV. The r410 uses DELL's PERC hardware.

Its as if multipath is screwing up my stuff.
Any clue as to how to get my data disks back?
