I have OMV 2.2.1 running on a Raspberry Pi 3B. I have BerryBoot on the SD card, a 120GB SSD on a USB carrier for the operating system drive, and currently 2 Seagate 1TB portable drives as shares.
Every time I reboot, it's a total roll of the dice which drives come up as /dev/sda, /sdb, /sdc. The good thing is that BerryBoot is smart enough to eventually find out which is the operating system drive, but the other two are random drive assignment.
Does this matter? Will OMV find and mount the shares regardless of their system ident?
