Cant add ZFS to storage, New node in cluster.

[p.lakis]

hey

So i added another node to my cluster,
Im using local ZFS only for VM data. I created the pool but cant mount it through cli or web interface.
I can add the zfs pool as a directory though but not as a ZFS pool.

the zfs pool shows in all outputs
# zfs list
# zpool status

Im thinking its something to do with the cluster? when i manually enter it in /etc/pve/storage the error says pool does not exist although i can see it through the zfs commands.

any help would be appreciated.

thanks

Is the dataset being read only, or not yet mounted?

Yes i can mount it as a DIR but not as a ZFS pool.

Head do the command line and run

zfs get all yourzpool

Or if you've got a dataset created,

zfs get all yourzpool/yourdataset

# zfs get all sn001vm/data

Well, that all looks fine, so you should be able to add it in the GUI. You also mentioned that you tried to add the storage at the CLI. Were you trying to do that by editing /etc/pve/storage.cnf? I worry about using a work around when you should be able to just make the storage entry in the standard way, but this may get you up and running. You could add an entry like this to stroage.cnf,

zfspool: displayname
        pool sn001vm/data
        content images,rootdir
        sparse 1

After restarting the entire cluster it worked.

So i guess that you cant import a zpool to an existing cluster??
