PVE 5.3 cluster iscsi storage issue

Hello all.
I have a cluster with 4 nodes and shared storage. The storage is connected to the cluster by iscsi with multipathing. Every works correctly, but I found some problem after testing. After rebooting one of the clusters, I can't perform migration back the vm's.
The error that I get:

Task viewer: VM 101 - Migrate

After 3 or more rebooting of the server, the error was gone. But if I reboot one of the servers from the cluster, the error occurs again.

Maybe someone is familiar with the problem, and can suggest something?

Thank you!
Yes, I saw this post. Thanks.
But I have installed multipath-tools.

Best regards
