problem with installing lustre and ofed
...es too, so I used this method to ensure OFED compiled against the correct kernel. This is on centos 6.3.
1. download all lustre rpms from whamcloud
2. install kernel, kernel-firmware, kernel-headers, and kernel-devel
* in this case, it''s the rpm files with "2.6.32-279.14.1.el6_lustre.x86_64" in their name
3. reboot into this lustre kernel
4. install the remaining rpms
5. download ofed from mellanox "MLNX_OFED_LINUX-1.5.3-3.1.0-rhel6.3-x86_64.iso"
* build mellanox ofed bits using the lustre kernel and kernel-devel info
* install mellanox ofed

Loop device performance
...0m5.430s
There are 5406 files that meet the filetype criteria.
When I run the script on the mounted loop device I get :
real 2m30.177s
user 0m2.290s
sys 0m4.880s
And immediate re-run gives me :
real 0m7.810s
user 0m2.187s
sys 0m5.360s
I`m usig lustre-2.4.0-2.6.32_358.6.2.el6_lustre.g230b174.x86_64_gd3f91c4.
Also set all of "small files" optimizations like, no striping for the dirs
containing the small files, max_dirty_mb=256, max_rpcs_in_flight=32,
staahead=8192 and lnet.debug=0.
Is it normal to get two times slower access times with the mounted loop
device ??
