Redundant supervisors
« on: August 14, 2009, 05:06:07 PM »

We recently had a disk go bad on our supervisor causing us to go down. I am now trying to implement a failover system for the supervisor. Was looking to do something with ucarp amd mysql replication but I see a bunch of references to having multiple supervisors in the docs but nothing definite. Is it possible to have multiple redundant supervisors? I fired up a second supervisor and they appeared to be talking to each other but it was not clear what was actually going on.

Any ideas?

We would recommend keeping it simple as you describe -- use mysql and file replication to a secondary machine.  If the main Supervisor goes down, the new machine can then be brought up with the same hostname and put in its place.   

There has been some work on multiple supervisors, but it is not a recommended route at this time.
