[DRBD-user] DRBD & Pacemaker

[Lucian Torje]

Hello,
I'm trying to configure DRBD & Pacemaker & Corosync & RabbitMQ and I need
some help in the following areas:

1) Is it possible to configure to use a file containing a filesystem in DRBD
( filesystem within another filesystem file) ?
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?

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):

$crm configure show
node ha-node1
node ha-node2
primitive bunny ocf:rabbitmq:rabbitmq-server \
    params mnesia_base="/mnt/drbd1"
primitive drbd ocf:linbit:drbd \
    params drbd_resource="drbd1" \
    op monitor interval="60s" \
    meta is-managed="true"
primitive drbd_fs ocf:heartbeat:Filesystem \
    params device="/dev/drbd0" directory="/mnt/drbd1" fstype="ext3"
ms drbd_ms drbd \
    meta master-max="1" master-node-max="1" clone-max="2" clone-node-max="1"
notify="true"
colocation bunny_on_fs inf: bunny drbd_fs
colocation fs_on_drbd inf: drbd_fs drbd_ms:Master

3) How can I mount a shared folder instead of DRDB just to test the rest of
configuration?

Thank you
