[Linux-cluster] first look at the released GFS source code

http://sources.redhat.com/cluster/ has a link to
http://sources.redhat.com/ml/cluster-cvs/ which gives 404.  On the same
page, there is also a link to usage.txt from CVS, which references
ftp://sources.redhat.com/pub/cluster/, and that directory also doesn't
seem to exist.

It would be easier for people to test this stuff if there were
pre-built kernel RPMs for their favourite distribution.  I can look
into doing this for Fedora Core 2 if noone else is doing that yet.

It is generally unclear to me how CLVM works, and what kind of shared
storage gfs needs.  I found links in many places to the GFS HOWTO at
http://www.sistina.com/gfs/Pages/howto.html, but that just redirects
me to RH's GFS sales pitch.

There are various references to sistina still in the tree:
./ccs/daemon/ccsd.c:#define DEFAULT_CCSD_LOCKFILE "/var/run/sistina/ccsd.pid"
./ccs/daemon/ccsd.c:  if(!strncmp(lockfile, "/var/run/sistina/", 17)){
./ccs/daemon/ccsd.c:    if(stat("/var/run/sistina", &stat_buf)){
./ccs/daemon/ccsd.c:      if(mkdir("/var/run/sistina", S_IRWXU)){
./ccs/daemon/ccsd.c:      log_err("/var/run/sistina is not a directory.\n"
./cman/tests/qwait.c:  (c) 2002 Sistina Software Inc.
./fence/agents/baytech/Makefile:        ${top_srcdir}/scripts/define2var ${top_srcdir}/config/copyright.cf perl SISTINA_COPYRIGHT >> $(TARGET)
./fence/agents/baytech/fence_baytech.pl:  print "$SISTINA_COPYRIGHT\n" if ( $SISTINA_COPYRIGHT );

./gulm/man/lock_gulmd.8:\fBlock_gulmd\fP does not create the \fIsistina\fR directory in the
./gulm/src/config_ccs.c:                                        "/var/run/sistina") );
./gulm/src/config_main.c:   gf->lock_file = strdup("/var/run/sistina");

I'm happy to see a generic cluster manager in your package (looking
into it now.)  I really hope there will eventually be a standard cluster
framework out there that everybody will use.
