How to make a DRBD node start itself as a primary node automatically?

pyruby · 01-28-2010, 11:57 PM

Hello. I've set up DRBD on 2 machines, 1 of them is the master, another is the slave.

After each bootup, I need to run the following on the master machine:

Code:

drbdadm -- --overwrite-data-of-peer primary all

Do we need to specify which machine should be the primary node every time? Is there any method to make the machine "know" it's itself the primary node? Thank you for your help.

You should specify in the DRBD configuration file (maybe /etc/drbd.conf for you) which node is the master and which node is the slave.
