pve-zsync for VM with multiple disks over multiple storages, seems not to work?

[mailinglists]

Should pve-zsync work for LXC VMs where VM has multiple disks across multiple storages?

I'm in a process of migrating some LXCs and just noticed that there are some disks missing on destination.

Job:

*/15 * * * * root pve-zsync sync --source 102 --dest XXX:hddpool/viri --name vm102 --maxsnap 2 --limit 50000 --method ssh --source-user root --dest-user root

Status:

Hi @mailinglists ,

No it is not possible because pve-zsync is based on zfs send-receive. So at a time you can replicate one pool source dataset to one pool dest dataset.

Good luck

Hmm.. why I couldn't sync both datasets and zvol sequentially, then shut down the LXC and sync the differences and start it in on the other side?
I guess I will have to manually sync the zfs datasets and use pve-zsync only for zvol to see why it would not work.
