Re: [Linux-cluster] Achieving a stable cluster with a 2.6.21 kernel

We would like to achieve a stable GFS/GFS2 cluster configuration using
a non-Redhat distribution that is based on a 2.6.21 kernel.  Our first
attempt was to obtain the Fedora Core 7 source rpms for the various
components (cman, rgmanager, openais, etc.).  We were successful in
incorporating these packages into our distribution, and creating what
should be a working cluster configuration with multiple nodes sharing
a set of GFS2 file systems from an iSCSI SAN.

The problem is that it is all very unstable, takes forever to
start-up, and locks up under even small load.

Use GFS1. GFS2 still does that. FC6+ no longer ships with GFS1 support built in as standard. If you're going to stick to the tried path, use RHEL5 (based) distributions. If you don't, you may well be better of just building the lot from source. It comes down to what your time is worth to you.
