This is blocking TT-120 ... We can't provision test nodes with OFA IB until this is fixed. I'll try provisioning an EL6 node and see if there are conflicts there, too.

Comment by Brian Murrell (Inactive) [ 03/Jun/11 ]

I think the path of least resistance here is to try to operate the OFED 1.5.x kernel space with RHEL5's 1.4.x userspace tools and libraries. In order to do this, the OFED 1.5.x kernel-ib RPM spec will need to be modified to remove the conflicts with RH's openib RPM as the previous comment demonstrates.

There is a build in lustre-reviews #799 which should fix this. If somebody gets to testing it before I do please report here on whether it resolves the issue or not.

Comment by Brian Murrell (Inactive) [ 06/Jun/11 ]

The previous build did not run a depmod for the kernel-ib modules after they were installed. A subsequent new build is in lustre-reviews (building as I write this) under build number 817. That one should install on rhel5/x86_64 (at least) and work with lnet. You can install it with loadjenkins, but of course change the -j and -b arguments accordingly.

If you get a chance to test it before me, please let me know how it goes. Otherwise I will be testing it in about 12 hours from now (assuming I can get nodes).

The build works:

loadjenkinsbuild -o -j lustre-reviews -b 817 -t server -d el5 -a x86_64 -i ofa -p test -r -n fat-amd-2

[root@fat-amd-2-ib ~]# rpm -qa | grep kernel

kernel-2.6.18-238.9.1.el5_lustre.20110525141730

The build works:

Great. Can you add a "+1 Verified" to the patch at review.whamcloud.com then? In general, if you verify that a particular patch that's in review works, it's helpful to set the verified flag on the review tool. Since there is comment space available when you add the +1 Verified, it's probably useful to point to the collateral that proves the verification, if any is available. In this case you could include the maloo link you have in your previous comment.

Thanx and cheers!
