Signals to all components the patch is intended for Lustre Janitor testing only. Jenkins will not build the patch (the status will be FAILURE) and therefore, Autotest will not test it. Your patch will not receive a +/- 1 from Maloo.

Test-Parameters: forjanitoronly

Signals to all components the patch should be completely ignored. Jenkins will not build the patch (the status will be FAILURE) and as a result it will not be tested by Autotest or the Lustre Janitor. Your patch will not receive a +/- 1 from Maloo.

Test-Parameters: ignore

Pass through options for auster.

Valid values: See "Auster usage help" section on the Setting up a Lustre Test Environment wiki.

austeroptions=-R

When true, the MGT will share a partition with an MDT. When false, AT will create an additional partition to be used by just the MGT.

NOTE: mdtfilesystemtype will override mgtfilesystemtype when combinedmdsmgs is true. If standalonemgs is set to true, this option will be ignored.

Valid values: true, false (no value is the same as true)

# creates a shared partition to be used by the MGT and a MDT - typically not necessary since this is the default
combinedmdsmgs
# or
combinedmdsmgs=true

# creates an additional partition to be used by the MGT
combinedmdsmgs=false

Comma separated environment definitions passed to the test environment. For definitions requiring spaces, enclose them in quotations.

NOTE: Be very careful setting environment variables directly (for example OSTFSTYPE=zfs) because Autotest creates a config file based on the environment it builds. If you ask for something at odds with Autotest's expectations you will see failure instead of success.  In this case, for example, you should use the filesystemtype keyword described on this page. Autotest will then create the appropriate environment variables, the same is true for other things like ostcount instead of OSTCOUNT, ostsizegb instead of OSTSIZE, etc. Only use the env  parameter when a direct variable is not listed here.

env=SLOW=yes
envdefinitions=SLOW=yes

# multiple definitions
env=ONLY=123,HONOR_EXCEPT=y

# one with spaces that must be enclosed in quotations
env=SLOW=yes,SANITY_EXCEPT="101g 102i"

Valid values: true, false (no value is the same as true)

# mark build as for build only
forbuildonly
# or
forbuildonly=true

# disable forbuildonly - typically not necessary since the default is false
forbuildonly=false

The fortestonly parameter marks that the patch is not intended for landing. Any testlist= specified with Test-Parameters: fortestonly will replace the default tests that will be run, so it is possible to run only a subset of tests.  Patches marked with fortestonly will not receive the Verified +1 label from Maloo and cannot be landed. In order to land such a patch, it should be rebased and submitted without the fortestonly keyword once the patch is known to be good, or the commit comment in Gerrit should be edited to remove the fortestonly label which will rebuild and retest the patch and will preserve any reviews that the patch has received).

Valid values: true, false (no value is the same as true)

# mark build as for test only
fortestonly
# or
fortestonly=true

# mark patch as experimental and run only a custom list of test
fortestonly testlist=conf-sanity

# disable fortestonly - typically not necessary since the default is false

# create 4 MDS nodes with 1 MDT each
mdscount=4 mdtcount=4

Sets the size of the partitions on the MDS in GB.

# configure a 2GB partition on the MGS
mgssizegb=2

Configure the file system type to use on the MGTs.

NOTE: The default value for combinedmdsmgs is true, therefore it must be set to false in order to configure a different file system type for the MGT. Also, <mdt/mgt/ost>filesystemtype should not be used in combination with fstype.

Valid values: ldiskfs, zfs

# configure the MGTs to use zfs
mgtfilesystemtype=zfs combinedmdsmgs=false

# configure the MGTs to use ldiskfs
mgtfilesystemype=ldiskfs combinedmdsmgs=false

# since combinedmdsmgs defaults to true, mgtfilesystemtype will be ignored and
# the MGT will use ldiskfs
mdtfilesystemtype=ldiskfs mgtfilesystemype=zfs
 
# do not do this - may result in an unexpected configuration
fstype=zfs mgtfilesystemtype=ldiskfs

Marks the test session as optional: does not impact the verified value from Maloo and is only run if resources are immediately available.

# configure 2GB partitions on the OSS
ostsizegb=2

When true, Autotest will continue the session after a suite crashes. The session will continue with the suite following the one that crashed. When false, Autotest will stop the session and upload the results to Maloo immediately.

Valid values: true, false (no value is the same as true)

# configure the session to continue after a suite crashes - typically not necessary since the default is true
resumeaftercrash
# or
resumeaftercrash=true

# configure the session to stop after a suite crashes

Valid values: lnet

# configure the session to run the lnet subproject test sessions
@lnet
# or
subproject=lnet

Configure the test session to run a specific test group. Specifying a test group makes it easy to run a typical test grouping with small modifications since the session will inherit all of the values from the base test with any overrides applied (see the code block below for examples).

NOTE: testgroup can be combined with testlist to run a test group plus additional suites

Valid values: See the Test Groups section for a complete list

# run a typical review-ldiskfs session with a stand alone MGS
testgroup=review-ldiskfs standalonemgs

# run failover with a specific server version
testgroup=failover serverversion=2.11.50

# run review-dne-part-1 with additional suites
testgroup=review-dne-part-1 testlist=sanity-lfsck,sanity-sec

Configure the test session to run a specific list of suites. testlist can be combined with testgroup to run a test group plus additional suites.

Valid values: sanity, sanityn, conf-sanity, mmp, replay-single, replay-dual, lnet-selftest, etc.

# run a custom list of suites
testlist=sanity,sanity-sec,sanity-hsm

# run review-dne-part-1 with additional suites
testlist=sanity-lfsck,sanity-sec testgroup=review-dne-part-1

Configures the session to re-provision all of the nodes instead of simply reboot them.

Valid values: true, false (no value is the same as true)

# re-provision nodes after a timeout
timeoutreprovision
# or
timeoutreprovision=true

# reboot the nodes after a timeout - typically not necessary since reboot is the default
timeoutreprovision=false

The trivial keyword can be used to reduce the testing time (both wall-clock time as well as total test system hours) for patches that do not affect code functionality, such as changes to whitespace, comments, man pages, and test scripts (in conjunction with the testlist keyword to ensure the modified test script is run if it isn't already).  Patches marked with trivial in the Test-Parameters: list will run the review-ldiskfs test session instead of the regular tests, so it currently runs only  sanity  and  lnet-selftest  to ensure basic functionality.  If changes are only being made to a test script outside of those already run by default, an additional testlist=<test-script(s)>keyword should be added with a comma-separated list of modified tests to ensure they are run to validate the changes.  The trivial keyword will reduce the test completion time from approximately 10h elapsed and 30h of total test system time to approximately 3h elapsed/system time.  This saves test system resources that may be better spent on other patches.

Valid values: true, false (no value is the same as true)

# mark the patch as trivial
trivial
# or
trivial=true

# mark the patch as non-trivial - typically not necessary since this is the default
trivial=false

serverbuildno=343 serverjob=lustre-master 

# this would fail since serverjob is not specified
serverbuildno=343

The number of nodes to use for the specified node type.

NOTE: For MDS and OSS nodes, it's best to also set mdtcount / ostcount to ensure you have the expected number of targets.

Valid values:

# configure session to run with 4 clients, 2 MDSs and 1 OSS
clientcount=4 mdscount=2 osscount=1

Distribution to use for the specified node type.

Valid values: el7, el7.5, el7.6, ubuntu1604, ubuntu1804, sles12sp3, etc. (The distribution specified must have been built for the patch being tested. The distros built can be seen on the patch's build page in Jenkins.)

# specify the client to use el7 and all servers sles12sp3

The version of Lustre to use for the specified node type.

Version cannot be specified with job and build.

If a distro is not specified in the test parameters, Autotest will use the highest el version available for the specified version.

Valid values: For a list of valid versions see the Versions section.

# specify patch level versions
clientversion=2.10.3 serverversion=2.11.0

# specify minor versions which uses the highest patch level version
