do a master and slave server have to be physically identical? i have 2 dl380 servers, both running 4gb ram. At the minute thats where the similarity ends as number 2 isnt configured its an empty brain. the first (server1) is all set up and running from your tutorials (thankyou falko) it has 4 146gb disks running 3 in raid5 and 1 spare. would server number 2 have to be setup with the same configuration? would i be able to use the server back up guide ghost4linux to copy all the info from server 1 to server 2 then change the name server1.myhost.com:192.168.101 to server2.myhost.com:192.168.102 and then follow the load balancer how to's?
