ZFS Pool Live Migration Question

[sockmunky]

Hello, Newbie here testing Proxmox.

I have a test environment running with two nodes in a cluster, currently working on adding my 3rd.
PVE01 has a zfs pool named Datastore01, PVE02 has different sized disks and its own zfs pool named Datastore02.

Under Cluster > Storage, I see each, set to their respective node. As far as I am aware, they are not shared. I thought I understood from reading documentation that each node can have its own separate zfs pool and I would still be able to migrate between them, but I receive the following error when I attempt to migrate a LXC container:

2024-05-08 16:25:35 ERROR: migration aborted (duration 00:00:00): storage 'Datastore02' is not available on node 'pve01'

Are LXC Containers not able to be migrated between nodes with separate zfs pools?

Thanks!

Edit: I just found in the documentation that LXCs require the same storage be defined if there are local volumes or mount points defined. Looks like that's my answer.

Hi sockmunky,

I think what you are searching for is the ZFS replication function

there is also a more intuitive GUI Guidance on youtube available - only in German - but with video and CC autotranslate EN - quite OK
it is important that the local ZFS pools on each cluster node must have the same name for ZFS Storage replication
