Re: [HPDD-discuss] Lustre 2.6.0 vs 2.5.3 on production systems
Thank you, Peter. That is helpful information. We are currently
leaning towards 2.6, but if the upgrade path from there to 2.7 is
simple, and can work with OST/MDT created under 2.6, then that may be
the path that we'll follow. We need to bring the new system online
quite soon.
Regards,
bob

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
