fsx(8) System Manager's Manual fsx(8) Name fsx - file system exerciser Syntax /usr/field/fsx [ -h ] [ -ofile ] [ -tn ] [ -fpath ] [ -pm ] Description The exerciser exercises a file system by spawning up to 250 (the default is 20) processes that create, open, write, close, open, read, val- idate, close, and unlink a test file. These test files are created in (the default) unless the -fpath option is used. The exerciser will run until or kill -15 pid is sent to the process. A logfile is made in for you to examine and then remove. If there are errors in the logfile, make sure you check the file, because that is where the driver and kernel error messages are saved. Options The options are: -h Print the help messages for the command. -ofile Save the output diagnostics in file. -tn Run time in minutes (n). The default is to run until the process receives a or a kill -15 pid. -pm Number (m) of processes to spawn. The maximum is 250; the default is 20. -fpath Path name of directory on file system you wish to test. For example, or The default is Examples The following example runs 10 processes on until the process receives a or kill -15 pid: % /usr/field/fsx -p10 -f/mnt The following example runs 20 processes on for 120 minutes in the background: % /usr/field/fsx -t120 & Restrictions If there is a need to run a system exerciser over an NFS link or on a diskless system there are some restrictions. For exercisers that need to write into a file system, such as the target file system must be writable by root. Also the directory, in which any of the exer- cisers are executed, must be writable by root because temporary files are written into the current directory. These latter restrictions are sometimes difficult to overcome because often NFS file systems are mounted in a way that prevents root from writing into them. Some of the restrictions may be overcome by copying the exerciser to another directory and then executing it. Avoid using the exerciser over an NFS or diskless file system.

netx(8) System Manager's Manual netx(8) Name netx - TCP/IP net exerciser Syntax /usr/field/netx [ -h ] [ -tn B ] [ -pm ] nodename Description The exerciser sets up a stream socket connection to the server in the TCP/IP internet domain. With connection made, the exerciser writes random data to the server; the server loops the data back to and the data is read and verified against the data written out. The exerciser runs in conjunction with the server. The exerciser by default will use the port number of the echo service in the file. Make sure that the TCP echo service is enabled in the file (no `#' in front of the service). The exerciser will run until or kill -15 pid is sent to the process. The nodename is the remote or local system host name running the server. Options The netx options are: -h Print the help message for the command. -tn Run time in minutes (n). The default is to run until the process receives or kill -15 pid. -pm Specify port number to use in internet domain (m < 32768). Note that this option is not used with the server, so you should never have to use this option. Restrictions If there is a need to run a system exerciser over an NFS link or on a diskless system, there are some restrictions. For exercisers that need to write into a file system, such as the target file system must be writable by root. Also the directory, in which any of the exer- cisers are executed, must be writable by root because temporary files are written into the current directory. These latter restrictions are sometimes difficult to overcome because often NFS file systems are mounted in a way that prevents root from writing into them. Some of the restrictions may be overcome by copying the exerciser to another directory and then executing it. Examples The following example exercises the TCP/IP network from the local host to node keel until a or kill -15 pid is received: % /usr/field/netx keel The following example exercises the TCP/IP network from the local host to node photon for 180 minutes in the background: % /usr/field/netx -t180 photon & See Also Guide to System Exercisers netx(8)
