[TriLUG] Linux Clustering (high availability) and file systems

[Tarus Balog]

Gang:

Okay, I want to make a particular file system highly available.

For example, suppose, just suppose, I had a directory called  
"/var/opennms" that I wanted multiple machines to be able to write to.  
So if I had two active machines writing to that file system, and one  
died, I'd have a third machine that could come on-line and pick up  
where the failed machine left off.

It has to be fast and reliable (so nothing like NFS). Has anyone worked  
with SAN equipment where we could dual attach two or more machines over  
SCSI or Fiber Channel?

How do Linux Clusters handle making data highly available.

Relevant links and RTFM suggestions welcome.
