NAME
nfstest_pnfs - Basic pNFS functional tests
SYNOPSIS
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.
read_write
Verify basic pNFS functionality on a couple of files opened for
reading 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
Verify traffic for file opened for read and write: writing file first.
one_ds
Verify client only connects to the DS with I/O.
rsize
Verify traffic for file using pNFS when mount option rsize < 4096.
wsize
Verify traffic for file using pNFS when mount option wsize < 4096.
rwsize
Verify traffic for file using pNFS when mount option rsize < 4096 and wsize < 4096.
nfsvers
Verify file created with pNFS is read correctly from different versions
of NFS. Also, verify files created with different versions of NFS are
read correctly from pNFS
all
Run all tests: read, write, read_write, write_read, read_lock,
write_lock, setattr, setattr_lock, rw_read, rw_write, one_ds, rsize,

NOTES
The user id in the local host must have access to run commands as root using the 'sudo'
command without the need for a password.
