If I umount the /dev/LVM-1/POSTFIX-2 ans restart DRBD I got:

And I can't promote it as primary because it's not UpToDate !
But /dev/LVM-1/POSTFIX-2 is *NOT* a raw partition but *ext3* !
Sam.
I think you are fundamentally misunderstanding how DRBD works.
I think too !
First and foremost; If you have anything valuable on this array, hire
someone in your area to help you.
Assuming you don't;
You should have:
- Raw device (/dev/sdXY or /dev/mdX)
- This device is set in /etc/drbd.conf or /etc/drbd.d/<resource>.res
- When you start DRBD, this will be used to create /dev/drbdX
- On top of /dev/drbdX, you create your partitions.
Ok, I thought it should be possible to sync/replicate a LVM as my
/dev/LVM-1/POSTFIX-2 is between 2 machine with DRBD.
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.
