Hi there!
We had a similar issue on our side: https://forum.proxmox.com/threads/network-issues-with-ceph-after-proxmox-node-restart-ovs-mtu-8900.163825/
You need to set arp_ignore=2 in sysctl.
Ist natürlich an valider Ansatz, aber ich bin da wiederum zu Faul. ;)
Ich favorisiere in so einer Konstellation lieber einen Cluster, auch gern Active/Backup, also alle VMs auf einem Node und die PBS VM dann auf dem anderen.
Wenn man Replikation...

The issue was caused by duplicate MAC addresses in the ARP table.
To resolve it, we configured the following on every Proxmox node:
We added these parameters to /etc/sysctl.conf (or to a dedicated file under /etc/sysctl.d/, e.g...
Ich habe die beiden Maschinen bewusst nicht im Cluster.
Die eine ist der Backupserver, der hält aber auch Ressourcen für interim Viertualisation bereit.
Wenn ich den eigentlichen VE Host patche, schiebe ich immer ein paar VMs kurz rüber.

Thanks for this, I somehow didn't turn this up while I was looking for a way to delay VM/CT startups. I just tried this out by moving my disks all back to the directory storage and adding a delay of 30s on the node, and things are looking good...
Now looks like all LUNs have 4 path after I run ( echo "- - -" > /sys/class/scsi_host/host4/scan ) for my both host. I have 2 host, host3 and host4. I run the command for both host.
Your requirements are in places contradictory and make no sense (fabric-on-ZFS or ZFS-over-fabric), you can’t have synchronous data over asynchronous systems. But those that aren’t in what you need is in Ceph and TrueNAS, both are plenty...
If both have ZFS I would go with ZFS send/receive since then you can also transfer the snapshots which together with zfs-auto-snapshot will give you a history of your files.
If you don't have ZFS on both sides I would go with a dedicated tool...
