Closing Today - Lustre Usage Survey
by OpenSFS Administration
Hello Lustre Community,
There are still a few hours remaining to submit your response to the Lustre
Usage Survey! Since the survey closes today, February 28th, we hope you'll
take a few minutes to provide your feedback in order to help us identify
Lustre usage trends and assist with future planning on releases.
The survey only takes a few minutes to complete and can be accessed at
https://www.surveymonkey.com/r/ZVZ2663. Note that all questions are
optional, so it is ok to submit a partially completed survey if you prefer
not to disclose some information. The results of the survey will be shared
at LUG 2018.
Thanks for your participation,
OpenSFS Administration

Since I have real experience as a Lustre admin, I turned to google, and it
looks like it might be that the file-locking daemon died (if Lustre has a
separate file-lock daemon), or somehow file-locking was recently disabled.
If that is possible, how do I check this, and restart or re-enable if
necessary? I skimmed the user manual, and could not find anything on
either of these issues.
Any and all help will be greatly appreciated.

Load Lustre modules during bootup
by Dzmitryj Jakavuk
Hello
I am looking for a proper way of booting RHEL 7 and ability to load lustre modules
My config is the following
options lnet networks=“o2ib0(ib0),tcp0(bond0)”
Lustre on ZFS
I have tried to load lustre modules using systemd-modules-load.service. It inserts zfs modules,ksocklnd and ko2iblnd but does not load lustre module with the “Network Down” error and the following error description
"Cant query IPoIB interface ib0: it’s down”
later on I have changed the boot order of systemd-modules-load.service to start after network service but still unavailable to load lustre module during startup
After logging to the shell I can ping other IPoIB interfaces
Can you please help with the proper config to have lustre module load during boot?
thank you
