Hi ViktorE,

it seems as if px1.zfs1 and px2.zfs1 are not restricted to the nodes that hold them (this can happen depending on how you created these pools). You can check in Datacenter->Storage and there click each of these. There you will find 'Nodes', where you can remove Node 'tkp-px1' from 'px2.zfs1' and Node 'tkp-px2' from 'px1.zfs1'. This should remove the 'pvesm status' errors.

For migration, you will need to select the appropriate storage -- say you have a vm on 'tkp-px1' with its disk on 'px1.zfs1'. If you migrate it to 'tkp-px2', you will need to select 'px2.zfs1' as 'Target Storage' (as there's no 'px1.zfs1' on 'tkp-px2').

Hope this helps!

Best,
Daniel
