December 31, 201312 yr I am having problems with Ubuntu clients losing track of unraid NFS shares. My plex server is consistently losing seasons of shows or wide swaths of my movie collection. The problem I think stems from 'stale NFS shares'. I have set the tunable factor on the NFS shares in unraid to -1, and set up cachedirs. But the problem remains. There is probably something I can do on the client side, but I don't know where to begin. The scene: One box, running XenServer. Unraid has the array drives passed to it at the PCI level. All other systems run on separate ubuntu VM's in the Xen environment. Shares to the ubuntu clients are done by NFS. The problem is happening across systems/VM's so I don't think it's isolated to my plex server, however it could be isolated to the ubuntu clients. I can post logs, if you tell me what log we need, or any other info needed.
January 2, 201412 yr Author I am running 5.0.4. I was mounting the shares on the clients during boot up with a fstab entry, but after looking around the internet for help with "Stale NFS file handle" I came to the realization that using NFS may be a poor solution given my setup. NFS shares apparently fail when one user changes the directory structure on the server while another user is connected to the share. I am not sure how this isn't a bigger problem for people (seems like it would be kind of huge). It could be that I just didn't have the NFS shares properly setup. In any case, I solved the problem another way. I installed Samba on the clients and share the unraid shares through samba instead of NFS. Problem solved. Plex doesn't forget where things are, and all appears to work correctly now. Unless someone tells me that under no circumstances should I use Samba, I am calling this case closed.
