NFSv4 Robustness testing

There are 3 tools used to test NFSv4 robustness. This tools are used to tests core filesystems functions : read/write/create ... in various configurations.

• fsstress : random sequence of FS operations performed by concurent processes.
• fsx
• ffsb

Each time a NFSv4 is able to complete one test sequence, this test should be conserved for non regression testing.

List of tests tools that should be usefull to test NFSv4.

Main results

Last kernel tested is Linux 2.6.12-rc3 more patches CITI_NFS4_ALL-4.

NFS v4 is able to complete this testes:

• fsx
• fsstress running 5 days in this configuration
  • 10 threads
  • 100 operation list lenght
• FFSB running 5hours with this profile:
  • num_files=1200000
  • num_dirs=100
  • max_filesize=4096
  • min_filesize=4096
  • num_threads=10
  • read_weight=3
  • write_weight=1
  • append_weight=1
  • write_random=1
  • write_size=4096
  • write_blocksize=4096
  • read_size=4096
  • read_blocksize=4096
