NFS 3 client filesystem (QNX Neutrino)
![]() |
You must be root to start this manager. |
fs-nfs3 [-b num] [-B size] [-D] [-e] [-h] [-i nodes] [-r] [-S] [-t] [-u] [-v[v]...] [-w sync=hard] [-Z n] server:export mountpoint [[-erStu] [-Z n] server:export mountpoint ...]
The following options apply to all mountpoints:
The following options apply only to the next mountpoint specified on the command line:
The default is none of these.
The fs-nfs3 filesystem manager is an NFS 3 client operating over TCP/IP. To use it, you must have an NFS server.
When you use fs-nfs3 with write caching (default), you achieve performance enhancements with respect to interoperability issues if more than one client accesses the same files on the server. You may use -w sync=hard to turn off write caching.
This filesystem manager requires a TCP/IP transport layer, such as the one provided by io-net with the npm-tcpip.so. It also needs socket.so and libc.so.
By default, this utility does not set any upper limit for number of inodes.
You can also create mountpoints with the mount command by specifying nfs for the type and -o ver3 as an option. You must start fs-nfs3 before creating mountpoints in this manner. If you start fs-nfs3 without any arguments, it runs in the background so you can use mount. The options that you can use with mount include the following:
Mount the qnx_bin export as /bin from an NFS server named server_node:
fs-nfs3 server_node:/qnx_bin /bin &
Mount /nfs1 using TCP, and /nfs3 using UDP:
fs-nfs3 -t host1:/ /nfs1 host2:/ /nfs3
Mount both using TCP:
fs-nfs3 -t host1:/ /nfs1 -t host2:/ /nfs3
Mount an NFS filesystem (fs-nfs3 must be running first):
mount -t nfs -o ver3 server_node:/qnx_bin /bin
Mount an NFS filesystem, using TCP (fs-nfs3 must be running first):
mount -t nfs -o tcp,ver3 server:/tmp /mnt
If possible, you should use fs-nfs3 instead of fs-nfs2.
