Hey all, is it possible to setup a second server with only -mysql (as slave configuration) - postfix with same mysql_virtual* + (my.cnf) - Apache and use glusterfs for redundant /var/vmail/* /var/www/* + Heartbeat for IP Service all other services are not needed. on slave. the slave server sql DB is read only (mysql) or could occour any Problems ? and one more Question: i had to restore an Backup from an ISPConfig 3 Server, by the mysql files, i had to remove all the Systemusers by my self. Is there a way to write a dump without the systemusers, to that i can import it on a "fresh installed new isp3 Server" ? the whole process took longer than 4 hours to restore the whole Server.. Thanks all!
