Bull GNU/Linux NFSv4 project

2.6.15-rc3 non-regression test

Tests performed

NFSv4 is tested using multiple tools on the same configuration but we are now using the linux 2.6.15-rc3-CITI_NFS4_ALL-1 kernel and CITI patch.

Test #1 : connectathon

• Client and server are running linux.

Test #2 : fstress:

• fsstress is run in various configurations and parameters

• Tests are done with various number of subprocess : 1, 2, 4, 8, 16, 32

• Tests are done with a various lenth of instructions lists: 1, 2, 4, 8, 16, 32, 64, 128

  Test #3 : fsx

• fsx is run with 5000 iterations (From LTP configuration)

Test #4 : locks testing

• Run Vincent's tests (integrated into the Linux Test Project) with 100 processes

Test #5 : ACL testing

• Client and server are running ACL CITI implementation

• The runned test suite runned is here

Results

Test #1 : connectathon

• Test run with success.

Test #2 : fstress:

• Test runs 2 hours without any failure.

Test #3: fsx

• Test run with success.

Test #4: locks

• Test run with success with 100 processes

Test #5: ACLs

• There is still a problem with long ACLs (longer than one page)

Core NFSv4 functions should be considered as stable. There is no regression with this kernel version.

Software configuration

•  Server:
• Export options are : /export         <world>(rw,wdelay,insecure,no_root_squash,no_subtree_check,fsid=0)
• mount options, NFSv4 : rsize=32768,wsize=32768,timeo=14,intr,noauto
• fsstress -l 0 -d /mnt/benchs_nfs/tmp/ -n <operation_sequence_lenght> -p <number_of_process> -r

Hardware configuration

Client and Server

• 2 processors : Intel(R)
• Xeon(TM) CPU 2.80GHz, cache 512 KB
• Total memory: 2Gb
• Ethernet: 1Gb/s link
• Distribution : modified Fedora Core 2
