Re: [PLUG] 3-way data mirror?

Might an OpenAFS file system (http://openafs.org) be an option? ÂPerhaps with SELinux used to disable updates at COLO that are not replicated from Lab1 and Lab2?

What I think I'd like to do is have:

   ÂLab1 <--> COLO <--> Lab2

The problem is that lab1 and lab2 are both read-write, so there is a real possibility of stepping on changes. ÂCOLO is read-only.

I'd try to just relay through the COLO, but that's also where the backup will happen. ÂAnd I can't get the FW rules changed.

Any better ideas?

Any suggestions on tools? ÂI'd strongly prefer something already in the CentOS-5 or EPEL repos.
