Re: [HPDD-discuss] Lustre 2.6.0 vs 2.5.3 on production systems
Hi Bob
I know that you are really looking for responses directly from sites
running the releases in production but a couple of things that you might
be helpful for you to know:
1) The recent OpenSFS survey 10 out of the 89 respondents said that they
were using 2.6 in production
2) Lustre 2.7 is expected to be released quite soon and will be more
current in kernel version, zfs version and bug fixes.
Regards
Peter

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
