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
