Live migration randomly fails

[Merlan Frit]

Hello,

I'm trying to migrate VMs from one of my 3 hosts. Some VMs moved flawlessly but some are giving me troubles. For some VMs, moving them from host 1 to host 2 didn't work but moving them to host 3 worked. The last VMs won't move anywhere. Here is the error message i got everytime :

[pve2] can't activate LV '/dev/vg_LUN1/vm-100-disk-0': device-mapper: create ioctl on vg_LUN1-vm--100--disk--0 LVM-UYHUcYpzFAJdeSYimLgTC6u7jh3kNayw92nzIORG942oPovKmtK8dfS1k4kUpp23 failed: Device or resource busy

It's a 3 nodes cluster, shared Iscsi Storage and pve-manager/8.2.4/faa83925c9641325 (running kernel: 6.8.8-4-pve).

What can i do to troubleshoot this ?
Thanks,
Matthieu

Once powered off, the VM moved but cannot start on other hosts. There are other running machines on the same LUN so i think it's not a LUN access problem

Ok, once cloned, the new VM moved. I think it's related to the ID of the vm that was reused (ID 100)
