Although it does happen during backups, causing serious issues that require Proxmox server restart, it also happens during the day. I don't see any saturation issues during the day, but I'll start monitoring that. So you're saying to set network bandwidth limits on the storage network (I do keep a separate network for storage). I guess upgrading the synology's with something that has 10GE would help as well.

[PVE-User] NFS Storage issue
Hi, I have a Synology with High Availability serving NFS storage to Proxmox. A couple of months ago, this started happening: Apr 24 12:32:51 proxmox-1 pvestatd[3298]: unable to activate storage 'NAS' - directory '/mnt/pve/NAS' does not exist or is unreachable Apr 24 13:08:00 proxmox-1 pvestatd[3298]: unable to activate storage 'NAS' - directory '/mnt/pve/NAS' does not exist or is unreachable It affecting backups and VM speeds. Any idea what is causing this? There are no errors in the Synology logs, and the storage stays mounted and accessible.
