Am I correct in this setup process:
Server A exists
Server B to be built
Stop Server A, take snapshot, record Master info.
Start Server A
Setup server B, Install snapshot from A
Set B up as a master
Set B up as a slave to A
Set A up as a slave to B, no need for binlog file or
position info as
it will start at the default 001 and pos 4
Circular replication is now running...
Did I mis anything?
Thanks,

If you are using InnoDB, then you do not need to stop server
A to take a
snapshot. (see http://dev.mysql.com/doc/mysql/en/mysqldump.html)
"The simultaneous use of --master-data and
--single-transaction works as
of MySQL 4.1.8. It provides a convenient way to make an
online backup
suitable for point-in-time recovery if tables are stored in
the InnoDB
storage engine."
As far as setting up the replication, that looks ok. Each
server needs
to have binary logging enabled, and needs to have the other
server as
it's master.

Nope, all tables are MyISAM.
There shouldn't be a problem if:
server A is ver 4.0.x
server B is ver 4.1.x
should there?
Thanks,
jeff
There could be problems with that.
