[SOLVED] Can I migrate between 2 lvms?

[Ivan Gersi]

I have 2 nodes cluster.

/etc/pve/storage.cfg 387/387 100%
dir: local
path /var/lib/vz
content vztmpl,backup,snippets,iso,images,rootdir
maxfiles 3
shared 1

lvmthin: local-lvm
thinpool data
vgname pve
content images,rootdir


lvmthin: del-hdd
thinpool del_hdd
vgname vmdata
content images,rootdir

You can see 2 lvms in pve3, pve2 has only local (lvm-thick). Can I migrate machine from pve3 to pve2?
I tried it but:

2019-10-21 19:29:07 starting migration of VM 110 to node 'pve2' (10.0.0.71)
2019-10-21 19:29:07 found local disk 'del-hdd:vm-110-disk-0' (in current VM config)
2019-10-21 19:29:07 copying disk images
Volume group "vmdata" not found

Ok I Tried rename lvm in pve2 to vmdata and then...

2019-10-21 19:36:41 starting migration of VM 110 to node 'pve2' (10.0.0.71)
2019-10-21 19:36:41 found local disk 'del-hdd:vm-110-disk-0' (in current VM config)
2019-10-21 19:36:41 copying disk images
lvcreate 'vmdata/vm-110-disk-0' error: Pool del_hdd not found in Volume group vmdata.

Is there any chance to migrate vm between nodes and lvm thin vs lvm?

I was succesfull again;o).
VM must running and then I can be able migrate.

qm migrate 110 pve2 --force 1 --online 1 --with-local-disks 1 --targetstorage local

Force is not neccesary
