Created test VM1 with 10 GB and VM2 with 10+10 GB without any OS.
Tested PDM migration:
1st try: VM1 slowed to hell
2nd try: VM2 succeeded
Remotes tests:
SERVER1: if=/dev/pve/vm-104-disk-1 bs=64k status=progress of=/dev/null - skipped due...
The same test as with Alpha version. The same remotes, upgraded to PVE 9. Migration of the 2nd disk stucked, manually stopped.
Remotes: pve-manager/9.0.6/49c767b70aeb6648 (running kernel: 6.14.11-1-pve)

What will happen, when you shutdown the 2nd SAN node?
What will happen, when you shutdown the 1st SAN node?

That's docker problem versus apparmor, not PVE related. Debian 12 didn't have active apparmor, but debian 13 has it by default. I encountered the same problem with giltab-runner + docker. Profile docker-default is created by docker service on the...
I have SAN with 3 luns connected with multiple destination's paths by multipath without problem. But i used mainly cli for configuration at the end, not gui. Looking on your debug, i think problem is somewhere
1] acl on SAN
2] iscsi/multipath...
Was it resolved?
I got the same problem, finally upgraded one of the Dell 740XD from pve 7 to pve 8 (Linux pve-18 6.8.12-13-pve #1 SMP PREEMPT_DYNAMIC PMX 6.8.12-13 (2025-07-22T10:00Z) x86_64 GNU/Linux) and every reboot:
Screen lost. Server...
It depends on requirements/hw. It's not different from running mailservers, db servers, webservers on the ceph. Every application has it's own performane. It works. It's performant? Test it. Ceph performance's tests are everywhere.
