Can't destroy container

[riri1310]

I create a container and the strange thing is that it was created on disk-0 and disk-1 (I notice that I need to do the creation process 2 times maybe it's for that, I don't know)
The thing is I want to destroy the container and I can't:

root@ns3128946:~# pct destroy 106
zfs error: cannot destroy 'rpool/subvol-106-disk-0': dataset is busy

root@ns3128946:~# zfs list -r -o name,mountpoint,mounted
NAME                     MOUNTPOINT                MOUNTED
rpool                    /rpool                        yes
rpool/ROOT               /rpool/ROOT                   yes
rpool/ROOT/pve-1         /                             yes

rpool/subvol-103-disk-0  /rpool/subvol-103-disk-0      yes
rpool/subvol-104-disk-0  /rpool/subvol-104-disk-0      yes
rpool/subvol-105-disk-0  /rpool/subvol-105-disk-0      yes
rpool/subvol-106-disk-0  /rpool/subvol-106-disk-0       no
rpool/subvol-106-disk-1  /rpool/subvol-106-disk-1      yes
rpool/swap

Any help please? I'm stuck

You could try to set "start at boot" to "No" and do a reboot.

Thanks I will try that.
Any idea why I have a 106 on disk-0 and disk-1?

The reboot works! Great thanks

I can detroy the container 106 (located on disk-0) but I still have the one on the disk-1 and I want to delete it too, any idea how I can do that if I can't use the detroy function?

you can either use pvesm free local-zfs:subvol-106-disk-1 or remove it via the web UI (select your storage in the sidebar and then go to the CT Volumes content view, where you can delete the image).

I have the same problem. I have only one volume with the CT, and it's not mounted.

# pct destroy 250
zfs error: cannot destroy 'poolz/vmdata/subvol-250-disk-0': dataset is busy

# zfs list -r -o name,mountpoint,mounted | grep subvol-250
poolz/vmdata/subvol-250-disk-0                /poolz/vmdata/subvol-250-disk-0  no

"do a reboot" of what, the hypervisor or the CT? I have a bunch of VM's and CT's on the hypervisor so I don't really want to reboot that nilly-willy.

What's the output of grep subvol-250-disk-0 /proc/*/mounts? Any snapshots on the dataset?

It would be a reboot of the host. But you could also try if re-mounting and unmounting again hellps?

I had to do a reboot for another reason and when it came back I could remove the container.
