Yes! If you use the drbddisk RA, then drbd needs to be launched by init and already running, when you start heartbeat. > Then I'm using drbd to synchronise the data of a web service (let's say > apache). > > On my first node, I mount the data /dev/drbd0 on /var/www/ for example, and > I want, if the node goes down, that the node2 takes the main hand, meaning > the service IPaddr, the drbd data AND the mount point to be done, so the web > server can start on the new node. I reviewed your CIB and there are some errors: Your group contains 3 resources in this order: IP, apache2, drbddisk That means at first the IP is startet, then apache and after that the drbd-volume is made primary on that node. I think the better (right?) order would be: 1. make drbd primary on that node (drbddisk-RA) 2. mount the filesystem (Filesystem-OCF-RA) 3. start the IP (IPaddr) 4. start apache2 > and finally, I want to be sure that if the heartbeat link goes down, the > dopd (drbd outdated peer daemon) to be sure it's working.
