hi,
After read the non-usage of uv's replication around the world I change
the technology.
I start to use DRBD (www.drbd.org) Data Replication by Device - "RAID-1
on LAN".
I'll publish a white paper about it with Universe when done.
Thanks for all of your comments.
If you're going to be setting up an HA cluster that syncs over a LAN
connection, you might also want to look into a stonith (shoot the other
node in the head) device. This is what we're using:
http://www.wti.com/rps-mcl.htm
It enables the backup node to kill the power to the primary node if the
two lose communication over the LAN. This prevents any users who may
have still had an active process on the primary from continuing to
update data once the backup becomes live. Additional info can be found
here:
