[killmasta93]

Hi,
i was currently rebooted the server and not sure what happed but the dataset seemed to got unmounted. i tried the following

root@prometheus4:~# zfs mount rpool/data/vm-109-disk-0

cannot open 'rpool/data/vm-109-disk-0': operation not applicable to datasets of this type

root@prometheus4:~# zfs get all rpool/data

Hi,

i don't really understand why you want to mount it.
It's type is volume and normally they're attached to VMs as disks.
Are you sure, that this dataset was mounted before?

 

[killmasta93]

thanks for the reply, i think it might been of pyznap that might of unmounted the volume
but not sure what happened when i run zfs list i dont see my vms and not sure how i can revert the way it was

 

[AKA]

I see what you mean.
I just didn't have time to give it a thought. I'll See what i can find and write news in here soon.

 

[killmasta93]

Thanks for the reply, what i did just format and reinstall i have no idea what happend

 

[AKA]

Did the reinstall solve the issue for you @killmasta93?

 

[killmasta93]

yes correct reinstalled i think what messed it up is that i tried using pyzsnap to send the snapshots though network i normally use that software to backup the snapshots on USB disk. But i guess ill stick with pve-zync
