ALL backups are failing with: unable to create temporary directory '/mnt/pve/backup/dump/vzdump-qemu-146-2020_02_12-02_00_02.tmp' at /usr/share/perl5/PVE/VZDump.pm line 703.

We export ZFS via nfs kernel server, working fine all the time. NFS shares are readonly now.

hi,

what's in your /etc/vzdump.conf
 
I have the same problem, is there a file that needs to set the no_root_squash or should I run the zfs command to set that? Thanks for any clarification.

the zfs command should be enough
 
So I ran the above command on my zpool/VMS and now when I create a VM on the zfs pool I get this error:

TASK ERROR: unable to create CT 10222 - zfs error: filesystem successfully created, but not shared


I must be missing a setting, but this pool is local and not shared in the cluster.

Any insight would be great..Thanks
