unable to start/mount container

[AxelTwin]

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:

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

 

[AxelTwin]

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

 

[dcsapak]

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

 

[AxelTwin]

we had to transfer the subvolume from rpool/data and the config file to a new proxmox on a new zfs pool

 

[dcsapak]

we had to transfer the subvolume from rpool/data

yes but how did you do it ?

 

[AxelTwin]

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.

 

[AxelTwin]

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

This seems to work
