Couldn't extract an UUID from the provided path #24

Hello,

I'm using OMV in a VM, with VirtIO-SCSI drives (which seems the recommended way now), and I cannot save the UnionFS config:

Couldn't extract an UUID from the provided path '/dev/disk/by-id/scsi-0QEMU_QEMU_HARDDISK_drive-scsi0-0-0-1'.

Error #0:
exception 'OMV\Exception' with message 'Couldn't extract an UUID from the provided path '/dev/disk/by-id/scsi-0QEMU_QEMU_HARDDISK_drive-scsi0-0-0-1'.' in /usr/share/php/openmediavault/system/filesystem/backend/mergerfs.inc:87

I'm using OMV v3.0.94 with UnionFS 3.1.17.

I'm trying to setup an union between all Tests-[1-4] drives.

Anyway, thanks for this plugin :) I'm using it in OMV2 and the switch from AUFS to MergerFS stopped my issue of ghosted files without perf issue (at least not with a few simultaneous writes).

Ok never mind, the mentionned disk was a leftover after I played with hot removal of SCSI disk. It was referenced in a share, and ever after removing it & rebooting I couldn't delete it, I had to edit OMV xml config manually to get ride of it. I let you close if you think there's nothing to do here.
