We are getting errors when trying to checkout b1_8_1 this morning. We get a ''no such tag b1_8_1'' error when checking out. Does someone have some pointers as to what we are doing wrong? We issued ./lustrecvs b1_8_1 We reterived the lustresvc script from cvs.lustre.org.

Robert 1.8.1 is not scheduled to be released until the end of July. Why do you expect such a tag to exist? What specifically are you trying to access?

We got the first Nehalem system last week, and it''s not very happy with our 2.6.22.19 patched kernel for Lustre. For our installation, based on Debian, a 1.8.1 supporting higher vanilla kernels would be big move forward.

Ralf Work to support 2.6.30 is taking place under bug 19808. It does not look like this will be ready in time for 1.8.1 but should make 1.8.2 Regards PJones Ralf Utermann wrote:> Peter Jones wrote: > >> Robert >> >> 1.8.1 is not scheduled to be released until the end of July.

As for server support, 2.6.30 won''t indeed be available before 1.8.2, although 1.8.1 introduces sles11 server support (and drops 2.6.22). Johann

Our question would be, whether 1.8.1 supports a 2.6.27 patched kernel. We did tests with patchless clients and were not very happy with the performance. And we need it for the serverside anyway.

And we need it for the serverside anyway.What kernel did you use to compare the performance? FYI, we removed the intent patches (used on the client side) for kernels >= 2.6.16. Basically, this means that patchless client is the default now, even if you use the patched kernel. Johann

I pulled out some test data from our internal wiki to http://www.physik.uni-augsburg.de/~ralfu/LustreTest/ where the data for unpatched and patched kernel are compared. Storage backend are two Sun 6140 systems, all OSTs either 4 or 8 data disks. As we were happy with the patched kernel results, we just did not look further into the obvious problems there. We might have to do this now ...
