Drive letters have changed

Hi,

I just set up my OMV5 on the Raspi4 with two disks. Since I had to unplug and replug them several times, it seems that they got assigned new drive letters.

The drive labeled "Filme" was on /sda once, and has now been assigned to /sdc. This has already been shared, but by Label.
The second drive labeled "Serien" has been assigned to /sde. I tried to configure a shared folder for this drive, but failed with the following error:

Fehler #0:
OMV\ExecException: Failed to execute command 'export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin; export LANG=C.UTF-8; blkid -p -o full '/dev/sda1' 2>&1' with exit code '2': blkid: error: /dev/sda1: No such file or directory in /usr/share/php/openmediavault/system/process.inc:182

How do I fix it? It seems that /sda is linked somewhere, but not found anymore... Can I manually rewrite in a specific file or maybe even manually change the drive letters for the drives? Also, why did they change in the first place, and how do I prevent that from happening?

Zitat von Adoby

As far as I know OMV doesn't care about the drive letters. It use the drive labels and uuid. Have you manually updated fstab or at any point used drive letters to specify drives?

Yes, indeed, I have had problems creating an EXT4 filesystem on the second HDD. I have used fstab to try and clean up the structure or whatever OMV told me to do.

Also, after rebooting, the letters got reassigned, and the error is gone, since /sda1 exists again.

Nonetheless, creating the shared folders, I was never able to specify the drive letters, but instead browse to the /sharedfolders. Also, if I click "reset" in the shown menu, it fills in the "drive" field with the UUID, so I wonder what /sda1 is needed for in the place.
