Hello, We have an IA64 cluster with 64K kernel page size and we use lustre 1.4.8.1 and e2fsprogs-1.39cfs8. We meet the following problem : 1.

I''ve just set up a small lustre installation on mixed SLES10 32-bit and SLES10 SP1 64-bit. 32-bit would give ksym errors upon installation of modules rpm, while 64-bit SP1 it was only warnings. I did a little research on the ksym package and it seemed to me it was only needed if you were trying to install a module compiled for a different kernel version. Since CFS is providing a

I notice that raid6 is recommended in the manual. eg. "...RAID6 is a must." http://manual.lustre.org/manual/LustreManual16_HTML/DynamicHTML-11-1.html which I found a bit surprising given that in Dec ''06 Peter Braam said on this list "Some of our customers experienced data corruption in the RAID6 layer.", and recommending the CFS optimised md raid5 path through the

Hello CFS, I was wondering if the new SLES10 kernel will be part of the 1.6.4 release. It appears to be tracked by: https://bugzilla.lustre.org/show_bug.cgi?id=13874 As this contains a major security fix (privilege escalation), it is a mandatory upgrade in many places and it would be nice to not have to roll our own kernel. Thanks, Kit

We have MpiBlast-1.4.0-pio and lustre-1.6.3 and we are seeing some pretty poor performance with most of the mpiblast threads spending 20% to 50% of their time in disk wait. We have the genbank nt database split into 24 fragments (one for each of our OSTs, 3 per OSS). The individual fragments are not striped due to the

What is the process for integrating a Lustre+SAMFS solution into an existing customer environment. The plan is to have CRS build the Lustre component, but Lustre and SAMFS will need to configured and integrated into the customer computing environment. I am very familiar with the SAMFS integration, but not Lustre integration. Do we have resources in PS to provide the integration? Is this

I''m switching all my fulltext searching over to ferret using the acts_as_ferret plugin on windows (for development, will be deployed on linux). In my tests I have a setup method as follows to ensure the index is reset for each test: def setup Item.rebuild_index end This works fine for the initial few tests but then suddenly fails for the last few tests when it seems to be
