<p>I have an NFS based PVC in a kubernetes cluster that I need to freeze to take a snapshot of.  I tried fsfreeze, but I get &quot;operation not supported&quot;.  I assume because it is trying to freeze the entire nfs instead of just the mount. I have checked and I can freeze the filesystem on the side of the NFS server. Is there a different way that I can stop writes to the filesystem to properly sync everything?</p>

<p>From <a href="https://github.com/vmware-tanzu/velero/issues/2042" rel="nofollow noreferrer">https://github.com/vmware-tanzu/velero/issues/2042</a> and some other quick poking around, fsfreeze doesn't support NFS mounts. In general it seems to mostly on work with real local volumes which you'll almost never use with Kubernetes.</p>
