I had the same issue. I could not find/get an answer, posted to this
same list about 1mo ago. I ended up down-grading to the same zfs I had
previously used, ie, 0.6.3.1 with Lustre 2.7.0
Maybe an answer has come round in the intervening month? But, it would
appear that if you use zfs, you are very heavily tied to the version of
Lustre built with that zfs.

Hello,
I recently encountered an issue with zfs on linux that required me to
upgrade to a newer version. Now I'm trying to patch my oss systems. I've got
a new oss (has never had its osts mounted) that I'm using to test the upgrade
process, but now that I've installed the new zfs modules it won't mount the
osts...
I'm running CentOS 6.5

When I do a /etc/init.d/lustre start it says that the lustre modules are not
loaded... and when I examine the /var/log/messages I see the following for each

So I tried reinstalling all the lustre rpms (including the kernel) but it still
gives the above message.
