All this programs are provided under the GPL, excepted SpecSFS. This tools
are mainly issued from two projects :
L.S.E : Linux Scalability Effort
L.T.P : Linux Tests Projects
| Non Reg capability | Performance evaluation | Robustness evaluation | NFSv3/v4 support | IPv4/IPv6 | POSIX conformance | Interoperability evaluation | RFC 3530 conformance | |

Nota :
All tests are interoperability evaluation capable, by testing all
NFSv4 clients/servers combinations.
To support NFSv4 and IPv6 the SpecSFS tool must be updated. According
to a first sizing, 11 month may be necessary.
A classical performances evaluation tool tests. The main
program tests database type access to a single file (or a set of files
if you wish to test more than 1G of storage), and it tests creation, reading,
and deleting of small files which can simulate the usage of programs such
as Squid, INN, or Maildir format email.
Dbench was written to allow independents developers to debug and test SAMBA.
It is heavily inspired of the original SAMBA tool : NetBench.
(LSE)
As NetBench it allow to:
But it does not need as many hardware resources as NetBench to run.
Performances tests suites. POSIX and 64 bits compliant. This tests is the
file system test from the L.S.E.
Main features:
This tool allow to set up a user specified amount of CPU, Disks IO, RAM
and HDD load, and then to launch the test suite. Any error is detected
and reported. It may be used to evaluate how well their systems will scale,
by kernel programmers to evaluate perceived performance characteristics,
and by systems programmers to expose the classes of bugs which only or
more frequently manifest themselves when the system is under heavy load.
A very flexible tool designed to evaluate NFS performances. fstress exports
control over several dimensions in both data set and workload, enabling
a wide range of tests for fundamental evaluation of file service scalability,
sizing, configuration, and other factors.
Fstress includes several important "canned" workloads.
This tool is an industry standard designed to test a NFS server by emulating
the NFS client and verifying the correctness of the result. Since the low
level protocol is verified, the tool is protocol dependent and must be
adapted to the NFSv4 and IPv6 support.
Dbench, fstress and SpecSFS are directly designed and used to test networks file systems.
OpenPOSIX is a tool designed to test the POSIX conformance. Currently,
the test allow to test pthread, timers and ipc related functions. However,
a few filesystems functions can be tested (open, close).
This test suite is the official suite of the connectathon to test clients/servers
interoperability.
PyNFS is the tool used to debug the Linux NFSv4 server. It maybe adapted
to verify the RFC compliance.
Mongo is the filesystem suite from the Reiser4 filesystem project. It is
a set of the programs to test linux filesystems for performance and functionality.
The main program is mongo.pl script which creates the set of statistics
for the file system variations specified by special mongo options. The
mongo_parser.pl script parses those statistics and creates for them comparative
html-table.
PostMark was designed to create a large pool of continually changing files
and to measure the transaction rates for a workload approximating a large
Internet electronic mail server. It generates an initial pool of random
text files ranging in size from a configurable low bound to a configurable
high bound. This file pool is of configurable size and can be located on
any accessible file system.
Once the pool has been created (also producing statistics on continuous
small file creation performance), a specified number of transactions occurs.
Each transaction consists of a pair of smaller transactions:
The Flexible Filesystem Benchmark (FFSB) is a cross-platform filesystem performance measurement tool. It uses customizable profiles to measure of different workloads, and it supports multiple groups of threads across multiple filesystems. Depending on the profile It can be used for robustness and stress testing as well as performances testing.
NFSx is the nfs vrsion of fsx. That is the fs torture suite used by the
LTP
to test the linux filesystem robustness. Initialisations scripts from the
ltp are yet modified to support the NFSv4 style syntax.
