Mounting filesystem with error The filesystem label contains blanks.

Hi,

After successful upgrade (new installation) from OMV 4.x to 5. x, I'm not able to mount two raid volumes (mounted before in omv 4.x without any issue)

You can see all my filesystems on attached picture.

Error #0:

OMV\Exception: The filesystem label contains blanks. in /usr/share/openmediavault/engined/rpc/filesystemmgmt.inc:892
Stack trace:
#0 [internal function]: Engined\Rpc\OMVRpcServiceFileSystemMgmt->mount(Array, Array)
#1 /usr/share/php/openmediavault/rpc/serviceabstract.inc(123): call_user_func_array(Array, Array)
#2 /usr/share/php/openmediavault/rpc/rpc.inc(86): OMV\Rpc\ServiceAbstract->callMethod('mount', Array, Array)
#3 /usr/sbin/omv-engined(537): OMV\Rpc\Rpc::call('FileSystemMgmt', 'mount', Array, Array, 1)
#4 {main}

I'll appreciate any advice.

I've solved problem by rename volume label.

sudo btrfs filesystem label /dev/mapper/vg1-volume_1 Backup1

Now no problem with mounting.
