Problem with online migration and disk migration


Jun 7, 2018
Hi! I have a 4 nodes cluster with a iscsi shared storage (LVM type storage) that contains the VM disks images.
When i tried to move a VM (with a disk allocated in the shared storafe) from a node to another node this fail:

migration status error: failed
ERROR: online migrate failure - aborting
aborting phase 2 - cleanup resources
ERROR: migration finished with problems (duration 00:00:11)
TASK ERROR: migration problems

A few days ago the migrations worked properly.
In the same way, when i try to move a VMs disk on the local storage to the shared storage i got an error:

TASK ERROR: storage migration failed: error with cfs lock 'storage-storageVMs': lvcreate 'VG_PROXMOX/pve-vm-106' error: Failed to write VG VG_PROXMOX.

any suggestions?
