since lustre version 2.10.1 intel build server has server rpms for el6.9 with in kernel ofed (but not on download server).
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 with patchless server (zfs or patchless ldiskfs ost).

It can be simpler path for us too  to upgrade existing lustre 2.5 system on el6.x to minimize downtime and to have rollback option - upgrade zfs and lustre; keep OS or do minor OS upgrade.
On new system we about to go live with 2.10.3 on slf 7.4.

Peter, Andreas,
do you test el6.x server to any extent? Is it worth trying to use it on test system?

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??
Depending on when they installed their system that may not be such a 'small' change, our 2.8 is running on CentOS 6.8 so an upgrade to 2.10 requires us to also upgrade the OS from 6.x to 7.x and though I very much want to do that that is a more intensive process that so far I have not had the time for and I can imagine others have the same issue.
