2.6.17-rc2-CITI_NFS4_ALL-1 regression tests

Tests performed

We are now testing the kernel and CITI patch: linux-2.6.17-rc2-CITI_NFS4_ALL-1
with the following tools:

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 : 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 50000 iterations (From LTP configuration)

Test #4 : Iozone

Run iozone -ace -U mountpoint

Test #5 : locks testing

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

Test #6 : 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

To Be Done

Core linux-2.6.17-rc2-CITI_NFS4_ALL-1 functions should be considered as stable. It fixes bugs found at Connectathon 2006 and Oops there were in 2.6.15-CITI_NFS4_ALL-3 and 2.6.16-CITI_NFS4_ALL-2. It integrates now the security flavors krb5, krb5i, krb5p (krb5p was missing in 2.6.16-CITI_NFS4_ALL-2)

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
kerberos MIT
fsstress -d /mnt/benchs_nfs/tmp/ -n <operation_sequence_lenght> -p <number_of_process>
