[Csync2] Csync2 feature request

[Dan Brown]

csync2 is a push technology.  If you want a younger file on web2 to be
transferred to web1, you'll need to be running csync2 -xv to be running on
web2.  Since you cannot (so as I've encountered) have both hosts running
csync2 -xv at the exact same time (one will drop out), running it every
other minute alternately on each host will work (although syncing will be a
max of 2 minutes lag rather than 1).  Depending on whehter or not your synch
will take longer than a minute, you may want to create a script which
creates lock files which are checked for via methods such as rsync so that
the other host does not interrupt a sync in progress.

Your other option (if you cannot or choose not to afford DA-SCSI, file
servers, etc) would be to abandon csync2 and use DRBD 8 + GFS(2)/OCFS in a
primary/primary role.

My feature request for this would be to allow csync2 to be run exactly at
the same time on two different hosts.
