Once the Linux client NFS mounts have been configured, their correct functioning can be easily verified by generating read and/or write traffic to the PowerScale cluster and viewing the OneFS performance statistics. Running a load generator like ‘iozone’ is a useful way to generate traffic on the NFS mount. The iozone utility can be invoked with its ‘-a’ flag to select full automatic mode. This produces output that covers all tested file operations for record sizes of 4k to 16M for file sizes of 64k to 512M.
# iozone -a
For example:
From the PowerScale cluster, if the multipath driver is working correctly the ‘isi statistics client’ CLI command output will show the Linux client connecting and generating traffic to all of the cluster’s nodes that are specified in the’ –remoteports’ option for the NFS mount.
# isi statistics client
For example:
Alternatively, from the client, the ‘netstat’ CLI command can be used from the Linux client to query the number of TCP connections established:
# netstat -an | grep 2049 | grep EST | sort -k 5
Note: On Linux systems, the ‘netstat’ command line utility typically requires the ‘net-tools’ package to be installed.
