Hi,

I recently tried to increase the swap space on a hp9000/340 cluster and ran
into a few problems.

	I did a backup, increased the swap and reloaded the system from tape.
This was great, I thought I was ahead of the game.  But I made 2 drastic
mistakes, the second much more severe.  First, I forgot to convert the new file
system to long filenames before I restored the file systems from the tape. 
(Not too bad, didn't lose anything important)  But I also forgot to convert
the system to a cluster environment before restoring the system.  (Makeing the
normal file system into a '3D' file system)  Consequently, I couldn't restore
the cluster, just the root server.  

	Not bad I thought, I'll just add them in by hand.  So I did, and then
I tried to do a 'ps' on one of the cnodes.  It keeps getting an error trying
to read the namelist.  But when I tell ps explicitly to look to /hp-ux 
(with the -n option to ps) ps works fine, no comlaints, it returns what should
be running on cnode.  

	When I first added the cnodes, it thought it was already a cluster, and
didn't try to convert it.  (The presence of the /etc/clusterconf file) So I 
mv'ed it and It still wouldn't create a cluster.  Since then I've restored all
the '3D' files (I believe) but still nothing from ps.


	My question, if you some to accept this mission, is what does 'ps'
depend on. (I thought it was just the /etc/ioctl.syscon file, but thats been 
restored and still nothing).  Thanks for any help/suggestions you can provide.
