Hi Alex
I’m afraid that although the builders are still in place and the patch series
remains in the tree, EL6.x servers have not been actively tested or maintained
for a long time on master and it would take some testing and engineering effort
to ensure that it was in a usable state. It’s poss
Ah, it sounds like HDF is using file locking to keep *other* possible users
out, rather than for its own consistency requirements. It's only trying to use
flock on Lustre because configure detects it's on a platform (Linux) that
supports flocks. But Lustre doesn't necessarily. That makes sens
ok, you are right, localflock might be a problem on parallel access, but at
least our code is started to work after that.just for information the
thread from hdf is following:

Are you sure HDF only ever uses flocks between threads on the same node? That
seems extremely unlikely or maybe impossible for HDF
we had similar troubles with hdf1.10 vs hdf1.8.x. on the lustre

Eli,
since lustre version 2.10.1 intel build server has server rpms for el6.9 with

e.g. 2.10.3 GA

It means lustre 2.10.x at least builds on el6.9 and I guess it shall be easier

If the mount on the users clients had the various options enabled, and
those aren't present in fstab, you'd end up with such behavior. Also 2.8?
Can you upgrade to 2.10 LTS??

That change provides the Lustre changes necessary to provide the support but
you would need to be using a version of ZFS that provides this option. As it
happens this work just landed to ZFS for the upcoming 0.8 release and so when
that is GA it should be possible to use this feature.
Hello,
is Project quota supported on Lustre 2.10.3/ZFS.
Apparently LU-7991 adds it as a feature.
Anyone may confirm it does work ?
thank you
Riccardo

No. Several others have asked me the same thing, so that seems like it
might be the issue. The only problem with that solution is that the user
claimed his program worked just fine up until a couple of weeks ago, so
if that is the issue, I'll still be scratching my head trying to figure
out how
Version 2.8.0 on the clients. Not sure what's on the servers, since I
don't manage them, and I can't find the guy who does at the moment.

Do you have flock option in fstab for lustre mount or in command you use to
mount lustre on client?
Search for flock on lustre wiki

Hi Prentice,
Is it possible that the file system isn't mounted with the "flock" option?
We're running an older Lustre 2.5, but we have to mount it with the
options "user_xattr,flock" to ensure everything is working.

My question is, Is it advisable to have /home in Lustre since users data

certainly it works, but is not very pleasant
for metadata-intensive activity, such as compiling.
