Lustre 1.6 Operations Manual

There are only two test types:
–-ping
–-brw
There are no private parameters for the ping test.
The brw test can have several options:
read | write
size=# | #K | #M
Read or write. The default is read.
I/O size can be bytes, KB or MB (i.e., size=1024, size=4K,
size=1M. The default is 4K bytes.
check=full | simple
A data validation check (checksum of data). The default is nocheck.
As an example:
$ lst add_group clients 192.168.1.[10-17]@tcp
$ lst add_group servers 192.168.10.[100-103]@tcp
$ lst add_batch bulkperf
$ lst add_test --batch bulkperf --loop 100 \
--concurrency 4 --distribute 4:2 --from clients \
brw WRITE size=16K
// add brw (WRITE, 16 KB) test to batch bulkperf, \
the test will run in 4 workitem, each
// 192.168.1.[10-13] will write to
192.168.10.[100,101]
// 192.168.1.[14-17] will write to
192.168.10.[102,103]
list_batch [NAME] [--test INDEX] [--active] [--invalid] [--server]
Lists batches in the current session or lists client|server nodes in a batch or a test.
–-test INDEX
Lists tests in a batch. If no option is used, all tests in the batch are listed. If
the option is used, only specified tests in the batch are listed.
$ lst list_batch

$ lst list_batch bulkperf
