Hello,<br>
I'm trying to configure DRBD & Pacemaker & Corosync &
RabbitMQ and I need some help in the following areas:<br>
<br>
1) Is it possible to configure to use a file containing a filesystem
in DRBD ( filesystem within another filesystem file) ?<br>
2) Pacemaker automatically mounts the drdb device on the master node
(the cluster contains a primary-secondary nodes) while the slave
doesn't have access in order not to corrupt the data, right?<br>
<br>
I have the following configuration and the filesystem was not
mounted for some reason (although DRBD management console displays
that drbd:r0 block device is synchronized and configured as
primary-secodary):<br>
<br>
$crm configure show<br>
node ha-node1
<br>
node ha-node2
<br>
primitive bunny ocf:rabbitmq:rabbitmq-server \
<br>

<br>

<br>
primitive drbd_fs ocf:heartbeat:Filesystem \
