Ocfs users - Mar 2004 - OCFS install trouble w/ new kernel - unresolved symbols

I successfully have OCFS running in a two-node RAC environment using RHAS
3 (2.4.21-4.EL) using Qlogic 2310 cards.  IO performance, however, was
terrible with the combination of OCFS and the Qlogic cards.  After
extensive testing, OCFS did fine on its own, as did the fibre cards.  Put
the two together, and everything literally ran twice as slow.

Support at Qlogic pointed me to
http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=104633, where there is
a test kernel that might resolve the problem (2.4.21-9.EL.noaffine2BOOT).
I installed the kernel and re-installed OCFS.  Though I tried the OCFS
RPMs, building OCFS from the source RPMs, and compiling from source code,
doing a ?load_ocfs? gets me a mismatched kernel messages, followd by a
long list of unresolved symbols.
(proc_mkdir_Rab0b93e0, find_or_create_page, etc).  I?ve tried using
ocfs-2.4.21-EL-1.0.10-1.i686.rpm, ocfs-2.4.21-EL-1.0.11-1.i686.rpm,
ocfs-2.4.21-EL-1.0.9-12.src.rpm, and ocfs-1.0.10.tar.gz.tar.

Any suggestions/ideas?

Many thanks,

Last I heard, Redhat had desupported the drivers for
QLogic 2310 on RHEL3.

The unresolved symbol issue can be resolved by
rebuilding ocfs with the patched kernel.
1. untar ocfs.
2. ./autogen --with-kernel=<path to the kernel>
3. make KVER=[up, smp]

Mind you, this (as in the personally built modules)
is not officially supported by Oracle.
