Does anybody here have experience with clustering on WBEL/RHES/AS?
I have a web-based application hosted on WBEL/PostgreSQL and am looking for
the best way to provide even higher uptimes. (So far, 30 minutes of unplanned
downtime in over a year)
I'm having some difficulty fully understanding what GFS is actually all about.
Is my understanding of GFS such that I could have two machines, each with
their own HDD, and have it set up with GFS as a sort of cross-machine RAID1?
If I could save data like this, and then replicate the PostgreSQL database
with Slony, I *think* I'd have a good solution for redundant servers at the
colo with minimal downtime in the event of a failure of either system... Am I
Ideas/thoughts/pointers? Has anybody here set up stuff like that?
Currently, we have two servers, a "live" server, and a hot backup which
synchronizes its filesystems periodically to the live server with rsync. This
gives a good "worst case scenario" recovery plan, but doesn't give much
support for lighter-grade failures.
