Hi Everyone, 

Is there any sort of ETA on 1.8.4?

Also,

I have attempted to build the OST/MDT rpms with the match mentioned by Chris previously against the current running lustre kernel src rpm (2.6.18.164-1.11.el5_lustre.1.8.2). When i install the RPMS lustre and lustre-modules that were built and attempt to remount the OST/MDT partitions i receive the following messages output for each partition. I've had to roll back to the rpms from the lustre website as they work.
