Hi,
Dattobd not working on the zfs file system and the logs below.
OS: CentOS 7.4
Urbackup Server: 2.2.11
Urbackup Clinet: 2.2.5

dmesg log:

I think the Snapshotting device(tank/dset) might be the problem because dattobd working with other file systems like xfs and ext4.
How can I achieve this on zfs file system otherwise how can I use zfs snapshot for backup?
Thanks
