I have two rhel 7 machines, each in a different data center connected by 10G ethernet.
I need to keep a folder in sync. Right now we have a cron job that does an rsync hourly. I'd like to do something more real time.
Unison might be an option but there's no official package for RHEL 7 nor is it in EPEL.
A distributed file system like GlusterFS probably wasn't really designed to span two data centers.
What would you use?
