Hi,
I'm having trouble with the live migration function of Proxmox cluster. With the original VMs when I tried to do a live migrate between hosts it would give me an error message about using local disks even when those VM disks were moved to an NFS storage or a gluster store flagged as shared.
"ERROR: migration aborted (duration 00:00:01): Failed to sync data - can't do online migration - VM uses local disks"

After creating a new VM on the nfs shared storage the local disk error went away and now it fails without a useful error message.
Mar 14 12:15:35 copying disk images
Mar 14 12:15:35 starting VM 112 on remote node 'vmhost3'
Mar 14 12:15:36 starting migration tunnel
Mar 14 12:15:37 starting online/live migration on port 60000
Mar 14 12:15:37 migrate_set_speed: 8589934592
Mar 14 12:15:37 migrate_set_downtime: 0.1
Mar 14 12:15:39 ERROR: online migrate failure - aborting
Mar 14 12:15:39 aborting phase 2 - cleanup resources
Mar 14 12:15:39 migrate_cancel
Mar 14 12:15:39 ERROR: migration finished with problems (duration 00:00:04)
TASK ERROR: migration problems

Is there a way to get a more detailed error message for the migration tool to find out what the error actually is? The pve/.debug option just gives a huge amount of debug data about the config cluster fs but very little else.

Hi,
you wrote, that the used storage is shared and also marked as shared. In this case I guess, you have ununsed disk-images on the local disk (or local storage.
