Review of actions from last meeting
======================

ACTION 2011-03-01 Xyratex to explore whether any existing Xyratex 2.x patches are appropriate for inclusion in the 2.1 release
-Still no progress on testing of LU145 patch ONGOING
ACTION 2011-03-01 ALL to contribute to 2.1 testing
-No progress on 2.1 testing at Terascala due to customer priorities ONGOING
ACTION 2011-04-26 LLNL to advise when RHEL6 testing is available on Hyperion
-Working through problems with software raid on MDS ONGOING


Testing update
==============

-TACC Testing with 1.8.5 clients seems good but hit one issue; LLNL suggested using a more current tag to avoid this issue
-ORNL Testing bottlenecks in metadata performance
-LLNL Unable to reproduce IOR error (LU437) with higher debug level; seeing some fragmentation but unclear if this is due to Lustre; will be testing powerpc soon
-Cray no progress this week
-Whamcloud focusing on adjusting to vm environment for review autotest this week

Blocker update
==============

-LU221\LU479\LU464\LU481\LU482\LU346 all due to switch in autotest system; several already have test script revisions undergoing testing and inspections already

-LU437 Trying to gather more info but less does not repro with higher debug level

-LU456 Patch waiting for autotest; Oleg does not think that this should be a blocker but it should land soon anyway

-LU468 Trying to reproduce this issue at TACC; still not able to even on RHEL6 which suggests something is missing in reproduction attempts

-LU477 RHEL5 version of 128TB LUN support landed; RHEL6 version needed; Whamcloud unable to test RHEL6 128TB LUNs at present so would welcome site to volunteer who could do so

AOB
