Is there a way for DRBD to first compare the local and remote mirror partitions to verify which one is newer before a sync is done?
Basically what happens is that I was running Partition 1 for a week with Partition 2 off. Then I turned Partition 1 off and turned Partition 2 on. When I turned Partition 1 on while Partition 2 was on, it synced Partition 2 to Partition overwriting files generated during the week that Partition 1 was on.
I may be misunderstanding the syncing process of DRBD. But I was hoping there's a way that DRBD would through up a warning when it sees a big difference between the mirror partition and ask the Admin to choose which partition to make primary.
Any guidance would be appreciated.
