NFS has a limit of 16 on the number of groups a user can belong to. If you have users with more than this, you need to enable the --manage-gids start-up flag for rpc.mountd on the NFS server. /etc/conf.d/nfs-server.conf # Options for rpc.mountd. # If you have a port-based firewall, you might want to set up # a fixed port here using the --port option. # See rpc.mountd(8) for more details. MOUNTD_OPTS="--manage-gids" "Permission denied" when trying to write files as root If you need to mount shares as root, and have full r/w access from the client, add the no_root_squash option to the export in /etc/exports: /var/cache/pacman/pkg 192.168.1.0/24(rw,no_subtree_check,no_root_squash) You must also add no_root_squash to the first line in /etc/exports: / 192.168.1.0/24(rw,fsid=root,no_root_squash,no_subtree_check) "RPC: Program not registered" when showmount -e command issued Make sure that nfs-server.service and rpcbind.service are running on the server site, see systemd.

See Files on a Mounted File System First, check to see if the file system is actually mounted. There are several ways of doing this. The most reliable way is to look at the file /proc/mounts, which will list all mounted filesystems and give details about them. If this doesn't work (for example if you don't have the /proc filesystem compiled into your kernel), you can type mount -f although you get less information. If the file system appears to be mounted, then you may have mounted another file system on top of it (in which case you should unmount and remount both volumes), or you may have exported the file system on the server before you mounted it there, in which case NFS is exporting the underlying mount point (if so then you need to restart NFS on the server). If the file system is not mounted, then attempt to mount it. If this does not work, see Symptom 3. 7.2. File requests hang or timeout waiting for access to the file This usually means that the client is unable to communicate with the server. See Symptom 3 letter b. 7.3. Unable to mount a file system There are two common errors that mount produces when it is unable to mount a volume. These are: failed, reason given by server: Permission denied This means that the server does not recognize that you have access to the volume. Check your /etc/exports file and make sure that the volume is exported and that your client has the right kind of access to it. For example, if a client only has read access then you have to mount the volume with the ro option rather than the rw option.Make sure that you have told NFS to register any changes you made to /etc/exports since starting nfsd by running the exportfs command. Be sure to type exportfs -ra to be extra certain that the exports are being re-read.Check the file /proc/fs/nfs/exports and make sure the volume and client are listed correctly. (You can also look at the file /var/lib/nfs/xtab for an unabridged list of how all the active export options are set.) If they are not, then you have not re-exported properly. If they are listed, make sure the server recognizes your client as being the machine you think it is. For example, you may have an old listing for the client in /etc/hosts that is throwing off the server, or you may not have listed the client's complete address and it may be resolving to a machine in a different domain. One trick is login to the server from the client via ssh or telnet; if you then type who, one of the listings should be your login session and the name of your client ma
