Right, That is what I had assumed...
I'm just wondering why it is generating such errors from an install of a RPM I
downloaded directly from Intel.

Ldiskfs is the default on disk file system for Lustre, used to format the disk volumes and
actually store the data, on the MDT, OSTs, and MGT. It's EXT4 derived.
It's possible to mount individual Lustre targets as ldiskfs, and is occasionally
necessary for troubleshooting. (So, it's a critical server component.)

Ahh,
modprobe does work for those, so I suppose it is ok. So what role does that package
play in the lustre file system? If it isn't necessary for the mds/mdt or the ost
systems then I'll pull it.

Kurt,
The ll_* errors, at least, are normal. The install order is such that
some symbols are undefined at install time for particular KOs, but are
defined in KOs that are installed later.
I am not familiar with the ldiskfs unknown symbol errors, but I haven't
installed the exact RPMs you're installing either.
If you can modprobe ldiskfs and fsfilt-ldiskfs after completing the
install, then these are probably the same as the ll_* - Undefined at
install time, but defined by later KOs.
