NAMEnfstest_pnfs - Basic pNFS functional tests
SYNOPSISnfstest_pnfs --server <server> [options]
DESCRIPTIONVerify 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.
OPTIONS--version show program's version number and exit -h, --help show this help message and exit -f FILE, --file=FILE File where options are specified besides the system wide file /etc/nfstest, user wide file $HOME/.nfstest or in the current directory .nfstest file

Test options:--runtest=RUNTEST Comma separated list of tests to run, if list starts with a '^' then all tests are run except the ones listed [default: 'all']
TESTS
readVerify basic pNFS functionality on a couple of files opened for reading within the same mount.
writeVerify 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_readVerify 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_lockVerify traffic for locked file opened for reading using pNFS.
write_lockVerify traffic for locked file opened for writing using pNFS.
setattrVerify setattr traffic for file using pNFS.
setattr_lockVerify setattr traffic for locked file using pNFS.
rw_readVerify traffic for file opened for read and write: reading file first.
rw_writeVerify traffic for file opened for read and write: writing file first.
one_dsVerify client only connects to the DS with I/O.
rsizeVerify traffic for file using pNFS when mount option rsize < 4096.
wsizeVerify traffic for file using pNFS when mount option wsize < 4096.
rwsizeVerify traffic for file using pNFS when mount option rsize < 4096 and wsize < 4096.
nfsversVerify 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
EXAMPLESThe only required option is --server
$ nfstest_pnfs --server 192.168.0.11
NOTESThe user id in the local host must have access to run commands as root using the 'sudo' command without the need for a password.
