lxc and zfs

[Cyber-web.be]

When i create a lxc container, i cannot select a zfs storage. I'm trying to create a new storage, reboot the machine but anything work. I'm working on proxmox 5.2-5.

It's possible to create a lxc container on a zfs storage and do a replication with another node ?

Thanks for your help, I'm a newbie.

Hi,

Yes, it is possible to use LXC on ZFS.

If you like the replica feature than ensure you create a storage from type "ZFS" also you have to set content-type "Container".
This config applies instantly.

Thanks for your answer. Please find the config, I think that it's ok but it's don't work
zfspool: mydata

You can use all zfs subset but not this two once ;-)

use instead of the rpool/DATA
if this is not available you have to create it.
see man zfs section create
