Hi I am getting the error:

Code: 
zfs error: For the delegated permission list, run: zfs allow|unallow

After attempting a snapshot of my container. There is little to no explanation to what this means, as far as I can tell.
 
Hi,

how do you make snapshots?
In the GUI or on the shell?
If you doing it on the shell what do you use as the command?
 
What language setting do you use?
 
Hi. Can you try on the shell:

Code: 
sudo pct snapshot ID snapsname

and post the output?
 
Code: 
oot@pve:/zvol/henry/hsync# pct snapshot 123 snapsname
cannot open 'zvol/henry/hsync/subvol-123-disk-1': dataset does not exist
usage:
        snapshot|snap [-r] [-o property=value] ... <filesystem|volume>@<snap> ...
For the property list, run: zfs set|get
snapshot create failed: starting cleanup
zfs error: For the delegated permission list, run: zfs allow|unallow

The error "dataset does not exist" is false.

subvol-123-disk-1 is there (along with a subvol-123-disk-0 that is not supposed to be there - re-creates itself for some reason)
 
I thought this could be related to the other forum thread you opened since it was the same container, but I'm starting to think it's not.

Please send the output of the following command:
Code: 
zfs list -t all
 
please include output of 'pveversion -v', 'zfs list' and 'pct config XXX' where XXX is your container's ID, as well as the content of '/etc/pve/storage.cfg'
 
Hi all, I discovered the SSD that my node was running on was failing. I reinstalled PVE on a new disk, and was able (with help) to recover my container and all seems well.

Cheers guys
