6.0 HP X9000 File Serving Software File System User Guide (TA768-96043, October 2011)

5 Using NFS
This section describes how to export file systems for NFS, how to autoconnect NFS clients, and
how to set up NFS clients.
Exporting a file system
Exporting a file system makes local directories available for NFS clients to mount. The management
console manages the table of exported file systems and distributes the information to the /etc/
exports files on the file serving nodes. All entries are automatically re-exported to NFS clients
and to the file serving node standbys unless you specify otherwise.
On the exporting file serving node, configure the number of NFS server threads based on the
expected workload. The default is 8 threads. If the node will service many clients, you can increase
the value to 16 or 64. To configure server threads, use the following command to change the
default value of RPCNFSDCOUNT in the /etc/sysconfig/nfs file from 8 to 16 or 64.
ibrix_host_tune –C –h HOSTS –o nfsdCount=64
A file system must be mounted before it can be exported.
NOTE: When configuring options for an NFS export, do not use the no_subtree_check
option. This option is not compatible with the X9000 software.
On the GUI
To export a file system from the GUI, select the file system, select NFS Exports from the lower
Navigator panel, and then select Export to display the Export Filesystem via NFS dialog box.
The Advanced tab displays additional options:
