Thanks for your help, I have to split my actual LVM physical partition but at this time I have: Device Boot Start End Blocks Id System /dev/sda1 1 25 200781 83 Linux <-- /boot /dev/sda2 26 2703 21511035 83 Linux <-- / /dev/sda3 2704 2965 2104515 82 Linux swap / Solaris /dev/sda4 2966 229467 1819377315 8e Linux LVM The / is for the Vserver host and vservers guests are on the LVM. My /dev/sda4 is 1.8To with a LV as Postfix machine (20Go), a LV as Zimbra server (500Go) and and the rest for LVM snapshot and testing partition. Does DRBD can work on extended partition ? If yes I will reconfigure my 2nd machine with a right DRBD config with 2 ressources, one for the Postfix machine and one for my Zimbra machine and then switch the apps on it and configure the 2nd machine as secondary. Thanks a lot for your explanation and your help, as well to all DRBD's users on this list. Sam.
