Hello,
I am running into an odd issue where my SYNOLOGY LUN is showing "?". I added a 2nd host/created a cluster today and the new host connected fine, but the old one still shows the same ?. I have rebooted both hosts and am trying to figure out why H1 (host 1) is continuing to show that the LUN is unavailable/offline but all the VMs are currently running and backing up from then LUN.

Someone recommended that THIS but I find it difficult to believe that PVE wouldn't have multipath enabled by default. The synology is already configured for multipath.
Here are results from my troubleshooting:
If I run on H2 (no VMs currently running from it) I get
storage.cfg file is IDENTICAL
and here is the multipath support check in Synology LUN
