proxmox-backup-client fails with "unable to open /mnt/vm/.chunks"

[lanepark5033]

After upgrading the PBS to proxmox-backup-client to 4.2.0 and the version of proxmox-backup-client on a standalone manjaro system to 4.2.0, backups fail with "unable to open /mnt/vm/.chunks". When looking at /mnt it is empty.
Here is the script I use to backup before 4.2.0.

sudo proxmox-backup-client backup datadisk.img:/dev/disk/by-id/ata-SSD_512GB_12012224H1447 --repository 192.168.4.89:lpbkup --backup-id datantfs

What am I missing ?

Did you check the filesystem backing your datastore is correctly mounted as expected on the PBS?

Good catch, Chris. The datastore was not mounted, I simply rebooted (systemctl reboot) the PBS and everything is back to normal and the raw backup is working. Now to figure out why the first poweron failed as I don't backup but once a week and the PBS is usually powered off. (The backstore is rotating disks, in a LVM pair totally 8TB.)
