Hi everyone.
I have a small question / problem about using drbd and heartbeat.
First, it seems that drbd launch is needed to start heartbeat correctly.
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.
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dopd (drbd outdated peer daemon) to be sure it's working. I think I'm
needing some help, but I dunno where to start :(
And then, last thing, I have a problem of drbddisk unmanaged resource on the
node1, does anybody know this ?
Thanks in advance,
Thibaut Perrin
