Yes, this is a problem.
We have worked on Lustre storage using Linux-HA, and I've come across
this problem.

You need to patch the /usr/lib/ocf/resource.d/heartbeat  script and
add 'lustre' into the list of filesystems which contains ext3 xfs etc.

I don't have the exact patch to hand (sorry)
Please could you try that and report back what the result is when you do
it?

Adding 'lustre' to this list of filesystems says "don't run an fsck on
me before mounting"
