Hi @okela ,
Do I understand it correctly that you attached iSCSI storage inside the VM using native Linux tools?
If so, then it's unlikely to be a Hypervisor (PVE) related problem. You should troubleshoot this the same as you would in a non-virtualized environment. Analyze the logs, look at the network health, check your storage logs, and reach out to your storage vendor.
Good luck
