Specify storage for guest replication

[Tmanok]

Hi PVE Team,

I was reading the admin guide and revisited local guest replication with two hosts having local-zfs and a question came up. How would you specify a secondary storage. For example, if my node has local-zfs and another JBOD eSAS enclosure running attached-zfs or similar, how would you specify which of the two storage repos to use?

Note that I've never used ZFS replication tasks in PVE so this may be obvious despite a lack of screenshots or CLI examples indicating otherwise in the admin guide.

Thanks!

One more question actually, in the replication docs, it mentions the config file of the guest must be copied to the other host. Is there no automated method within the pve environment to do this? Replication is valuable but only if the VM can be quickly booted on another node, the primary reason for this would be if the source node fails (poweroff).

Is this another case where an rsync task to a separate admin archive should be employed? Or perhaps to each of the nodes? Currently I use these to copy files in /etc on each of my nodes to a small repository separate from my cluster.

Thanks,

How would you specify a secondary storage.

This seems to be impossible without additional tools. For native PVE you need to have the same datastore on the destination of a replication task.

I had asked the same question just a few days ago: https://forum.proxmox.com/threads/datastore-emulating-one-by-another.106777/

Oh jeez, really? Pardon me, that was pretty ignorant of me to ask then.
Thanks Udo, really too bad that isn't a feature yet.

No problem!
I myself did also not realize that this wish/problem is not new ;-)

Best regards
