This change makes additions to the ZFS test suite that allows the performance tests to run over NFS. The test is run and performance data collected from the server side, while IO is generated on the NFS client. This has been tested with Linux and illumos NFS clients.

DESCRIPTION:
|
|
ZFS Test Suite launch script
|
|
|
|
OPTIONS:
|
|
-h Show this message
|
|
-v Verbose zfs-tests.sh output
|
|
-q Quiet test-runner output
|
|
-x Remove all testpools, dm, lo, and files (unsafe)
|
|
-k Disable cleanup after test failure
|
|
-f Use files only, disables block device tests
|
|
-S Enable stack tracer (negative performance impact)
|
|
-c Only create and populate constrained path
|
|
-n NFSFILE Use the nfsfile to determine the NFS configuration
|
|
-I NUM Number of iterations
|
|
-d DIR Use DIR for files and loopback devices
|
|
-s SIZE Use vdevs of SIZE (default: 4G)
|
|
-r RUNFILE Run tests in RUNFILE (default: linux.run)
|
|
-t PATH Run single test at PATH relative to test suite
|
|
-T TAGS Comma separated list of tags (default: 'functional')
|
|
-u USER Run single test as USER (default: root)

|
|
|
EXAMPLES:
|
|
# Run the default (linux) suite of tests and output the configuration used.
