[HPDD-discuss] Lustre 2.6.0 vs 2.5.3 on production systems

Hi, We are about to set up a new Lustre system here, and we are trying to decide between using 2.5.3 or 2.6.0 . Files in our older 2.1.6 system will simply be migrated over, and the old system tossed down the tubes. Is anyone using 2.6.0 in production? I found this on some 2.6.0 performance data, and it looks rather discouraging. https://jira.hpdd.intel.com/browse/LU-4841?filter=10828 I have also noticed that the 2.5.3 server rpms actually use a slightly newer kernel than the 2.6.0 set. By and large, we will use zfs underlying the OST. So, I will gladly accept any advice on which way we should turn as we set this up. Thanks, bob
