New Cluster and FreeNAS Appliance - Setup recommendations needed

[udo]

OK, failed again.

I created a small test VM (vm-103) on the master node with a 4Gb RAW disk stored on the local LVM (Storage) and tried doing a migrate from node1 to node2:

The web interface shows VM-103 on Node2, and if I click on it and look at the hardware tab I can see a hard disk listed, but the path/name is the same as the original node. In other words, the Volume ID is the same as it was on node1: Storage:vm-103-disk-1. But there is no LVM volume on node2 names Storage like there is on node1, just the standard pve local storage. Does that explanation make sense? =)

Hi,
this looks like that your VM was on storage which you defined as shared (mean, all cluster member has access to the same storage). Proxmox can not know, that this isn't true.

Make the storage not as shared and proxmox ve will copy the disk-content.

Udo, you were right, the local LVM was set to shared storage. I disabled that, created another test VM and tried other test:

/usr/sbin/qmigrate 10.10.10.103 104
Feb 19 07:46:15 starting migration of VM 104 to host '10.10.10.103'
Feb 19 07:46:15 copying disk images
Feb 19 07:46:15 Failed to sync data - can't migrate 'Storage:vm-104-disk-1' - storagy type 'lvm' not supported
Feb 19 07:46:15 migration aborted
VM 104 migration failed

It does not seem to like that I have the disk image in a local LVM store for some reason.

Please can you post the VM configuration. And the storage.cfg too?

Storage.cfg:

dir: local
    disable
    path /var/lib/vz
    content images,iso,vztmpl,rootdir

lvm: Storage
    vgname vmstore
    content images

Yes, storage migration for local lvm is still not implemented.
