Unable to mount NFS share from fstab, cmd line works fine #mount #fstab #nfs

https://askubuntu.com/q/1552780/612

I have an NFS server running on the Raspberry Pi (with RPi OS), and I can't get my OpenBSD laptop to mount it.

OpenBSD will mount my Samba server in the Thunar file manager, but I'd rather mount that share in the terminal (or via fstab), and I don't think there's a way to do that.

Why you should use NFSv4 over NFSv3 in your Proxmox cluster - the difference is huge!

And if NFS has still too high latencies for you, my upcoming post of NVMe-oF (TCP) with SPDK will solve your issues.

Not even bad the latency (this is just about latency, not overall bandwidth which reaches the full 4.9Gbit via 2x 2.5Gbit links).

Taken inside a Debian VM running on a Proxmox node connected to the storage:

GMKTec G9 NAS
2x 2.5Gbit
NFS 4.2 (with pNFS)
2x WD Back SN7100 NVMe
Mirror mode ZFS

While this are already pretty awesome latencies, let's see how it performs with SPDK and NVMe-oF (TCP).

""We recently ran across a strange higgs-bugson that manifested itself in a critical system […] A higgs-bugson is a bug that is reported in practice but difficult to reproduce, […]

The Linux kernel does not actually implement this cache as suggested by the RFC, so I wrote a kernel patch to add this functionality and mailed it off upstream. I also learned that the FreeBSD kernel actually already implements this, so this is new-to-Linux but not new-to-NFS.

[…]

Both of these patches are now upstream and will be available in Linux 6.16.""

Got a strange one

Forgejo Helm install with the PV being a mounted NFS volume from a Synology NAS

Every now and again the Avatar icon for one of the orgainistaions stops loading and throws internal errors claiming to not have permission to read the file.

If I ssh into the NAS and run ls in the folder it all works again.

NFS: the "Not For Sure" filesystem.

Try writing several hundred thousand files, and one or two won't, or worse, will do so truncated. Doesn't matter if from python or from java, calling sync on the file handle or not. Some will fail. Writing software as crashware that can rerun operations when needed is a good way to cope with this.

In retrospect, it's amazing it works at all, considering – multiple computers, each with many CPU cores, all hitting the same file system at once.

Been testing out the #virtiofs support now baked into #proxmoxVE. It works, had to do some #selinux adjustments on #fedora to allow my #podman containers to use the mountpoint. Added this policy

```
(allow container_t unlabeled_t ( dir ( read write )))
```

In raw speed it is definitely not a winner - #nfs is easily double the speed. But on this particular VM I don't need the speed - it is nice that this is all self-contained now, and I can actually remove NFS altogether.

Das Modell könnte die zukünftige Suche nach bewohnbaren Planeten im Universum deutlich beschleunigen und damit revolutionieren."

Is storage live migration with a running VM possible in #OpenNebula?
Say if I want to migrate from #NFS to #Ceph RBD while the VM keeps running on the same host?
