[Ocfs-users] OCFS install trouble w/ new kernel - unresolved

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.

>(proc_mkdir_Rab0b93e0, find_or_create_page, etc). I’ve tried using
>ocfs-2.4.21-EL-1.0.9-12.src.rpm, and ocfs-1.0.10.tar.gz.tar.
