Home-Server is running RTM (Fresh Install) all users and connect software installed before files were copied across. I am now getting this error to nearly every file on the home server, it has become quite annoying, Contact the administrator of this server to find out if you have access to this resource. You might not have permission to use this network resource.

The most complete and definitive resource on understanding the Network File System (NFS) anywhere. If that's still too long for you, then we should talk about preventing this from happening in the first place. If five minutes is too long for you, then you can use * * * * * /home/engineer/Desktop/staleHandleDestroyer instead which will run q1m (every minute). If it finds a stale file handle, it will automatically unmount them (lazy umount is safest, so that's what I use above) and then attempt to remount. The above cron job will run every five minutes, searching for stale file handles. Sudo crontab -e */5 * * * * /home/engineer/Desktop/staleHandleDestroyer

Sudo chmod +x /home/engineer/Desktop/staleHandleDestroyer If you want to discuss your specific use case, please comment below! It’s hard to create a one-size-fits-all script because a lot of it depends on how the client is accessing the NFS share, but this should work for the majority of Linux/Ubuntu/Debian installations. List=$(df 2>&1 | grep 'Stale file handle' | awk '' | tr -d \:) Nano /home/engineer/Desktop/staleHandleDestroyer

So here's how to better equip your NFS clients to automatically resolve stale file handle errors when they happen (and they will).įirst, if you're here for just a one-off fix, you can resolve the issue with: umount -l /path/to/NFS/mount/hereīut let's say you don't to want to have to actively seek out stale NFS mounts and want your Linux NFS client to just handle it automatically. Besides, unfortunately, these errors can't always be prevented. It's always best to understand how your NFS shares are being used, but that's another topic for another time. When it comes to NFS stale file handle errors, an "ounce of prevention is worth a pound of cure". How To Automatically Fix NFS Stale File Handle Errors The answer is any change in the mounted file's underlying inode, disk device, or inode generation on the NFS server causes an NFS stale filehandle. What causes an NFS stale file handle error? So what could cause this reference to go out of date and no longer be valid? I.e. We've also established that a "stale file handle" error means that this reference is out-of-date or otherwise invalid. We've established that a filehandle (which represents a file on a NFS server) contains information about the file's inode, disk device, and inode generation on the NFS server. What causes an NFS "stale file handle" error? More importantly, an NFS client has no idea what other operations are going on with the files/directories it has mounted, so when a filehandle becomes invalid (or "stale"), the NFS server returns a "stale file handle" error in response to the client. Even if the client could decode the filehandle, the client doesn't have direct access to the file system or disks on the NFS server and therefore that filehandle with its inode, disk, and inode generation data mean nothing to it. What does "NFS Stale File Handle" error mean?Īgain, filehandles are essentially meaningless to the client that is mounting an NFS share. As such, the filehandle is essentially meaningless to the NFS client that has an NFS share mounted.

In most instances, this pointer is an amalgamation of an inode, disk device, and inode generation of the referenced file on the server. In this guide, we'll talk about methods you can use to equip your NFS clients to recover automatically from stale file handle errors.īasically, an NFS filehandle is a pointer on the NFS server to the actual file (or directory). NFS Stale File Handles can be one of the most frustrating problems when it comes to network-attached storage (NAS).
