Thanks, Patrick! I do realize I'm off in development territory here and
that is the mandate of my project so we're expecting a little "see what
happens". I decided it would be better to try our luck on Lustre-dev on a
newer, 3.x kernel, than go back to 2.6.x and try to run i.e. MD with older,
perhaps more stable, Lustre. I had some unpleasant experiences with MD RAID
back on 2.6.x and I'm not eager to see if it acts any differently on CentOS
versus Ubuntu! :O I will give that a try and I'll report back to the list
if I encounter anything strange or something that smells like a potential
bug.
Best,
Sean

Sean,
Just a heads up first: Remember you're installing an unreleased
development version. It has not seen the testing and finalization of a
release version. You're basically signing up to experience some extra bugs
that wouldn't be in a release version.
That said, if you're going to run that version, you want to run the latest
e2fsprogs, which you linked at the end. They install over the top.

Subject: [HPDD-discuss] Which e2fsprogs on Centos 7 with most recent
Lustre 2.7.x build from Git?
Hi all, quick question; I got all my packages built and I'm going through
installing and now I'm looking at section 30.4.1; it steers me to this URL:
https://wiki.hpdd.intel.com/display/PUB/Lustre+Releases
At that URL, regarding e2fsprogs, it just has the somewhat cryptic note:
"Users are encouraged to always run the latest version of e2fsprogs on
their servers."
Does this mean there is no longer a separately maintained e2fsprogs for
Lustre ... I can just use the stock package in CentOS 7?
If I go to the slightly different URL:
https://wiki.hpdd.intel.com/display/PUB/Lustre+Tools
It's telling me to go to the Whamcloud site and download what they have
... but the revision on this page is 2012, so maybe that's stale
information?
Or ... I see there are actually packages available using CentOS/RHEL 7
available here:
https://downloads.hpdd.intel.com/public/e2fsprogs/latest/el7/
Install those over the stock e2fsprogs that comes with CentOS 7?
Thanks,
Sean
