Move PVE OS to new disk(s)

[WSDJamie]

Hello,
I have proxmox installed on a ZFS mirrored set of SATADOMS. The SATADOMS are terrible and i'm needing to move the OS to some SSDs instead.
I'd really rather not start a fresh install if I don't have to.

Does anyone have any tips on moving the Proxmox OS to new disks?

I guess one way I could do it would be to add the 2.5 inch SSDs to the mirror pool, resilver the data and then remove the SATADOMS. But I wonder what other ideas are out there.

I would advice to instead do a new pool with your new drives and use zfs send and zfs receive.

Note that special care should be taken if the pool contains a bootable device as in this case, see [1], section "Changing a failed bootable device".

Adding the devices to the pool and resilvering should work if the new drives are at least bigger than the old ones but I would recommend to use send and receive instead.
