Replicate non zfs to zfs filesystem?

[openaspace]

Hi.
It's possible to replicate from proxmox a VM from non zfs system to a zfs system?

I have an hold host with mdadm raid10 hardware.. and new host with zfs file system.

Thanks

Unfortunately no. The replication mechanism is based on the send / receive functionality of ZFS.

If you want to move a VM to the new host temporarily (to maybe resetup the old host with zfs) you can use the live migration functionality to migrate the running VM.

Also be aware that the ZFS storages should have the same name accross nodes.

Really thank-you.
The ZFS replication could be used also over wan with high latency near to 15ms?
or use only manual live migration over wan?

Thanks.

For live migration the servers need to be part of a cluster.

Proxmox VE uses Corosync for the cluster functionality and corosync likes low latency. I've heard of people running clusters in such a situation but the rule of thumb is to have lower latency. 2ms would be great, depending on who you ask you will hear that 8 or even 10ms are still okay.

This has been discussed quite a bit. A search in the forum should give you more insight.

If you want to replicate VMs to another Datacenter as a cold fallback have a look at pve-zsync. https://pve.proxmox.com/wiki/PVE-zsync
