opaverifyhosts(8) Master map: IFSFFCLIRG (Man Page) opaverifyhosts(8)

NAME

opaverifyhosts

Verifies basic node configuration and performance by running FF_HOSTVERIFY_DIR/hostverify.sh on all specified hosts.

NOTE: Prior to using opaverifyhosts, copy the sample file /usr/share/opa/samples/hostverify.sh to FF_HOSTVERIFY_DIR and edit it to set the appropriate configuration and performance expectations and select which tests to run by default. On the first run for a given node, use the -c option so that hostverify.sh gets copied to each node.

FF_HOSTVERIFY_DIR defines both the location of hostverify.sh and the destination of the hostverify.res output file. FF_HOSTVERIFY_DIR is configured in the /etc/opa/opafastfabric.conf file.

A summary of results is appended to the FF_RESULT_DIR/verifyhosts.res file. A punchlist of failures is also appended to the FF_RESULT_DIR/punchlist.csv file. Only failures are shown on stdout.

Syntax

opaverifyhosts [-kc] [-f hostfile] [-u upload_file] [-d upload_dir]
[-h hosts] [-T timelimit] [-F filename] [ test...]

Options

--help
Produces full help text.

-k
At start and end of verification, kills any existing hostverify or xhpl jobs on the hosts.

-c
Copies hostverify.sh to hosts first, useful if you have edited it.

Specifies the file with hosts in cluster.
Default is /etc/opa/hosts.

-h hosts
Specifies the list of hosts to ping.

-u upload_file
Specifies the filename to upload hostverify.res to after verification to allow backup and review of the detailed results for each node. The default upload destination file is hostverify.res. If -u '' is specified, no upload occurs.

-d upload_dir
Specifies the directory to upload result from each host to. Default is uploads.

-T timelimit
Specifies the time limit in seconds for host to complete tests. Default is 300 seconds (5 minutes).

-F filename
Specifies the filename of hostverify script to use. Default is /root/hostverify.sh.

test
Specifies one or more specific tests to run. See
/usr/share/opa/samples/hostverify.sh for a list of available tests.
