Easiest way should be to create a backup of every LXC and import it. While importing you can choose where to store your "new" LXC. There you can select your new SSD.

hi,

if you add the SSD disk as a storage device, you should be able to move containers' volumes there.

pct move_volume <vmid> <volume> <storage>

e.g., if you added your SSD as a storage with name my_ssd and want to move a container 123's rootfs there:
pct move_volume 123 rootfs my_ssd should move it.

if you want to move all the containers rootfs, you can put this in a loop:

CTIDS=$(pct list | awk '{print $1}') # get a list of all containers
for CTID in ${CTIDS}; do pct move_volume ${CTID} rootfs my_ssd; done

if you have other mountpoints attached you'll need to specify them separately

Hello, so we put a new server SSD into the cluster, this server is on ZFS and the old server HDD is on LVM, i would like to migrate them but i receive this error ..



The old :

The new :

It's maybe because they don't have the same name, but it's possible to put the same name ?

Can someone tell me why i can't ?

Have a nice day !

with live-migration, you should be able to select the target storage in the Web UI. Otherwise, you can use the --targetstorage option in the CLI.
