Hi everybody.
We are having trouble to start containers that we imported from another node.
They were not moved from backup/restore process, we transfered the disk and the config file from old to new server.

here is the output when we try to mount the container:

Code:
root@proxmox1:~# pct mount 112
cannot open 'rpool/subvol-112-disk-0': dataset does not exist
mounting container failed
command 'zfs set 'acltype=posixacl' rpool/subvol-112-disk-0' failed: exit code 1

there is no subvolume 'subvol-112-disk-0' .. i am not sure you transferred the disks, but this disk is still missing
 
the disk has been transfered.
apparently we are facing issues with the disks where acl are set to "enable". the container doesn't start if they are not set to default. I did it and the container started but it messes up everything with samba. the AD not working, people can't access their shares....
I am having really bad time with the cuistomers right now.
I don't know what to do, I opened a ticket with support, hope,they will pick it up soon and find a solution
 
the disk has been transfered.
did you only transfer the data and not the actual subvolume?

if yes, then what you have to do is:

1. move the data away (e.g. mv /rpool/subvol.... /rpool/tmpsubvolu...)
2. create the subvolume by hand ( zfs create /rpool/subvol.... )
3. copy the data back
 
we had to transfer the subvolume from rpool/data and the config file to a new proxmox on a new zfs pool
 
rsync from old proxmox to new one
I created a subvolume and transfered the data inside the old subvolume to the new one
the zfs-pool and dataset were created during installation.

if yes, then what you have to do is:

1. move the data away (e.g. mv /rpool/subvol.... /rpool/tmpsubvolu...)

3. copy the data back

This seems to work
