Description

I recently built lustre-2.3.0 client on sles11sp2. When I tried to load the libcfs module, it failed:

1. modprobe libcfs
   FATAL: Error inserting libcfs (/lib/modules/3.0.42-0.7.3.20121219-nasuv/updates/kernel/net/lustre/libcfs.ko): Operation not permitted

The /var/log/message said:

The sles11sp1 version of lustre client 2.3.0 worked fine for me. I have scraped the systems so comparison is not available at this point.

There must be an easy answer for this problem, but my searching for answer came out empty. Please help! My testing of lustre-client 2.3.0 on sles11sp2 stalls. Shoudn't a default value just work?

I thought I tested 2.3.0 on sles11sp2 before, but I was wrong. It was 2.3.0 on sles11sp1 that I tested.
