Hi all,
I'm having problems with the drbd resync after a node failure. This is
what I do:
- Make sure the master and slave are in sync
- pull the power
- Write some data to the slave that's became active
- shutdown the slave
- start the master. The master is waiting till the slave becomes online
- start the slave
Since I wrote data on the slave I expect the slave will sync to the
master. However that's not the case. Then slave thinks, as far as I can
see in the logs, that no blocks need to be sync. Anybody an idea what's
going wrong:
The (relevant) logs from the master:
