Hi. > 1) - First of all is the LVM on DRBD is really fiable in production mode ? Yes. Definitely. > 2) - In case of DRBD crash on primary is it tools to recovery the > filesystem and what about the secondary ? I'm not familiar with any use cases. DRBD does not make it a habit to destroy your filesystems as far as I know. If things really go awry, I can picture both your Primary and Secondary dying. Never heard of anything like that actually occuring, though. > 3) - To migrate to the new setup I have to configure the secondary > machine with only one machine as primary to create the logical volume > and install the vservers.

You can also scrap and replace your slave at any time, new slaves will seemlessly sync themselves to your Primary. Cheers, Felix
