Hi. We upgraded one of our ProxMox hosts ( version 7.2.1 ) using its web ui last week and after that the connection to our storage system (FCoE) was lost. We use multipath for that and the command "multpath -ll" is returning nothing since then. So we have installed again ProxMox 7.2.1 from scratch and it is working fine, but we cannot upgrade anymore or the storage connection will be lost. Has anyone of you guys faced this kind of problem ? Thanks.
Versions:
Linux 5.15.60-1pve
pve manager 7.2.11
 
Its unlikely that any userland software (Proxmox) caused your issue. Its more likely to be related to kernel.
Do you know:
- What Kernel you were running prior to upgrade?
- What Kernel did you upgrade to?
- What Kernel are you running now?

You may be able to trace things back by using "journalctl -b[1-9]" and looking for "Linux version" line.
Once you identify which kernel works and which one doesnt, you can start comparing boot messages between the two. Also you can try to "modinfo" relevant drivers.
Its possible that newer kernel requires FC card firmware upgrade.

bbgeek17. We were running Linux 5.15.60 and the upgrade will install 5.15.64.
In fact, after we had the problem we ran some tests. One of them was to boot using kernel 5.15.30 and it works, the storage came alive again.

So its possible that that newer kernel was the problem. Next step upgrade firmware of FC cards.
Thanks.
