nfstest_pnfs ā€” 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.

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

Examples

The only required option is --server
$ nfstest_pnfs --server 192.168.0.11

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.
