I'm wondering what is a realistic limit for using a NAS sever against a Proxmox cluster (or two).
I currently have a 16TB NAS (8 drives) server running freeNAS. I have two Proxmox clusters, each with about 50 VMs spread across 13 nodes. The NAS storage has an iSCSI initiator for each cluster. Each cluster talks to the NAS over separate networks each with its own 10GB network interface.
Is there a real limit that I should be looking at for NAS utilization? All 100 VMs in use across both clusters use the NAS as their storage over iSCSI. After about a year, I'm starting to see disk errors in the VM guests and I'm pretty sure it's due to overloading the NAS.
Right now I've moved the VM disk images back to local storage and haven't seen the disk errors that have happened over the past few weeks with NAS as the storage medium. My current plan is to build another NAS so that each cluster has its own NAS storage and not shared.
