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.
