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)

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.

# multiple definitions

Sets the file system type for all server nodes (MDS, MGS and OSS).

NOTE: fstype should not be used in combination with <mdt/mgt/ost>filesystemtype.

Valid values: ldiskfs, zfs

Configure the file system type to use on the MDTs.

NOTE: <mdt/mgt/ost>filesystemtype should not be used in combination with fstype.

Sets the size of the partition on the MGS in GB. This value is only applicable when the session is using a stand alone MGS.

Valid values: > 0 and must be an integer. When setting this value, take into consideration that most test nodes have ~90GB of disk space.

# configureset aall 2GBserver partitionnodes onto theuse MGSzfs
mgssizegbfstype=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 file system type to use on the MDTs.

NOTE: <mdt/mgt/ost>filesystemtype should not be used in combination with fstype

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

Valid values: > 0 and must be an integer. When setting this value, take into consideration your ostcount value and that most test nodes have ~90GB of disk space.

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-provisionconfigure nodes2GB afterpartitions a timeout

Marks the session as enforcing: is used to determine the verified value from Maloo.

Valid values

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)

Provisions a separate test node as the MGS. The MGS will be setup with the same parameters as the MDS unless they're overwritten.

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