Configuring NFS exports (optional)

The GUI provides the easiest way to configure NFS exports. For more information, see “Using

NFS” in the HP X9000 File Serving Software File System User Guide.

NOTE: On the Export Filesystem via NFS dialog box, change the path as needed to meet customer

requirements. The default value for path is the root directory of the file system. The other default

values on the dialog box should be adequate for most sites.

NFS client implementation tuning

NFS clients perform best when the file system policy on the X9000 file servers is tuned to prefer

LOCAL segments and ROUNDROBIN. This tuning ensures that NFS client writes will not suffer a

network hop penalty on writes to remote file serving nodes. To implement the tuning, place the

following script on the management console in /root, make the script executable and then run

it. The script runs commands necessary to tune servers for NFS performance.

#!/bin/bash

# LOCAL + ROUNDROBIN for NFS to write to local segments

# Do this for each segment server in your IBRIX Cluster

ibrix_fs -l |tail -n +3 |awk '{ print $1 }' > /tmp/.fs

ibrix_server -l |tail -n +3 |awk '{ print $1 }' > /tmp/.hosts

for fs in `(tac /tmp/.fs)`

for host in `(tac /tmp/.hosts)`

echo "ibrix_fs_tune on ${host}${i} LOCAL and ROUNDROBIN"

/usr/local/ibrix/bin/ibrix_fs_tune -f ${fs} -h ${host} -S LOCAL

/usr/local/ibrix/bin/ibrix_fs_tune -f ${fs} -h ${host} -p ROUNDROBIN

# This holds more files in cache (memory)

echo "Tuning cache on ${host}"

/usr/local/ibrix/bin/ibrix_host_tune -S -h ${host} -o "deleg_lru_high_wm=2000000,deleg_lru_low_wm=1999000"

# Set's the IBRIX threads to 64, this is similar to NFS threads

echo "setting IBRIX threads to 64"

/usr/local/ibrix/bin/ibrix_host_tune -t 64 -h ${host}

echo "Now set the NFS threads to 64 on your segment servers in /etc/sysconfig/nfs variable RPCNFSDCOUNT, I do

not do this automatically incase you already tuned your NFS"

done

Configuring CIFS shares (optional)

NOTE: Before attempting to configure CIFS, ensure that the DNS entries for the user network IP

addresses have PTR (reverse lookup) records configured.

When setting up CIFS, you will need to configure user authentication and then create CIFS shares.

For more information, see the following:

• “Configuring authentication for CIFS, FTP, and HTTP” in the HP X9000 File Serving Software

File System User Guide

• “Using CIFS” in the HP X9000 File Serving Software File System User Guide

• Managing X9000 CIFS Shares in an Active Directory Environment Quick Start Guide

Configuring other X9000 Software features

See the HP X9000 File Serving Software File System User Guide for information about configuring

the following features:

• HTTP/HTTPS

• FTP/FTPS

• Remote replication

• Data retention and validation

• Software snapshots
