nfstest_pnfs: Basic pNFS functional tests
NAME
nfstest_pnfs - Basic pNFS functional testsSYNOPSIS
nfstest_pnfs --server <server> [options]DESCRIPTION
Verify basic pNFS functionality for file (both READ and WRITE), including opening a second file within the same mount and having a lock on the file. Also, verify basic pNFS functionality for a file opened for both READ and WRITE while reading the file first and then writing to it or the other way around by writing to the file fist and then reading the file. These tests verify proper functionality of pNFS and NFSv4.1 as well.

TESTS
read
Verify basic pNFS functionality on a couple of files opened for reading within the same mount.
write
Verify basic pNFS functionality on a couple of files opened for writing and then re-opening the first file for writing within the same mount.
write_read
Verify basic pNFS functionality on a couple of files opened for writing and then re-opening the first file for reading within the same mount.
read_lock
Verify traffic for locked file opened for reading using pNFS.
write_lock
Verify traffic for locked file opened for writing using pNFS.
setattr
Verify setattr traffic for file using pNFS.
setattr_lock
Verify setattr traffic for locked file using pNFS.
rw_read
Verify traffic for file opened for read and write: reading file first.
rw_write

one_ds
Verify client only connects to the DS with I/O.
rsize
