Hi all,
Well, looks like DragonDisk (http://www.dragondisk.com/) deal with RRDNS well, it just run with both RGWs ;)
But what actually I need to know now is why RGW not start at boot time with "Initialization timeout, failed to initialize" error in logs. It run successful by hands after that.

difference between that and load balancing is that one server serves the
clients until it dies, then another takes over. With load balancing, all
servers get a share of the requests. It can be configured to do HA: set
"main" server's share to 100%, then the backup will get no requests as
long as the main is up.
RRDNS is a load balancing solution. Dep. on the implementation it can
simply return a list of IPs instead of a single IP for the host name,
then it's up to the client to pick one. A simple stupid client may
always pick the first one. A simple stupid server may always return the
list in the same order. That could be how all your clients always pick
the same server.
