Dan Zeng I’ve seen a lot of people struggling with NFS setup and backup planning on Proxmox, especially when running multi-node environments. Since NFS plays a big role in shared storage and centralized backups, getting it right really matters. I found a guide that explains the whole setup clearly—from configuring NFS on Linux to adding it in Proxmox—and it also covers an easier backup option with Vinchin. If you’re working on this, the article is definitely worth checking out.
Silas Nice share! NFS can be surprisingly tricky on Proxmox, especially in clusters. A clear guide like this is always helpful—thanks for posting it!
Julian Moreland Great summary! NFS can be tricky in multi-node setups—this guide clears things up nicely.
Curtis Stanhope I've just started using Proxmox, and I'm constantly getting "storage not reachable" errors after setting up multiple nodes with NFS. Could someone please provide a minimal working example of an /etc/exports file and the corresponding mount command? I'm a beginner and would really appreciate an example! 🙏
Sylas Beaumont Curtis Stanhope Simple example: /srv/pve/backups 10.0.10.0/24(rw,sync,no_subtree_check,root_squash) Then run exportfs -ra, and on the client: mount -t nfs -o vers=4 10.0.0.5:/srv/pve/backups /mnt/test
Vincent Question for everyone: In a multi-node Proxmox cluster, what are the most common root causes when an NFS mount is lost? Is it network issues or permission problems? I've encountered this twice recently, both due to DNS resolution issues... Does anyone have any statistical experience with this?
Quentin Vincent The troubleshooting order I recommend is: Network (VLAN/MTU/routing) > Storage service (rpcbind/nfs-server) > Permissions/UID mismatch > DNS/hosts misconfiguration. Following this order will save time during troubleshooting.
