When you 'rebase' there is no relay file on either side. Thats the whole 
point of doing a rebase from scratch. Essentially, you'd do something 
like this on the master :

Service mysqld stop; cd /var/lib/mysql/ ; rm -f mysqld-bin.* ; rm 
master.info; rm relay*.info ; lvcreate -s -n mysql-snap -L 10G 
/dev/VolGroup00/LogVol00 ; service mysqld start; mkdir /mnt/mysql-snap; 
mount /dev/VolGroup00/mysql-snap /mnt/mysql-snap; ssh root at replica 
/sbin/service mysqld stop; rsync --delete -Pvar /mnt/mysql-snap/* 
root at replica:/var/lib/mysql/ ; ssh root at replica /sbin/service mysqld start

If you still use the old legacy way of specifying the replica param's on 
the replica machine, things should just work from there. if you specify 
them on the cli, then login to the replica mysql, and 'change master to
master_host...' make sure you set position to '0' since the master would 
have started writing new binlogs.

Also, dont top post, and trim your posts.
