order mysql_after_drbd inf: ms_drbd_mysql:promote mysql:start
is committed ok, but it doesn't show right in the configuration:
primitive fs_mysql ocf:heartbeat:Filesystem \
params device="/dev/drbd0" directory="/service/" fstype="ext3"
primitive ip_mysql ocf:heartbeat:IPaddr2 \
params ip="192.168.1.72" nic="eth2:0"
primitive mysqld lsb:mysql
primitive apache lsb:apache2
primitive drbd_mysql ocf:linbit:drbd \
params drbd_resource="r0" \
operations $id="drbd_mysql-ops" \
op monitor interval="15s"
group mysql fs_mysql ip_mysql mysqld apache
ms ms_drbd_mysql drbd_mysql \
meta master-max="1" master-node-max="1" clone-max="2"
clone-node-max="1" notify="true"
colocation mysql_on_drbd INFINITY: mysql ms_drbd_mysql:Master
order mysql_after_drbd INFINITY:
property $id="cib-bootstrap-options" \
dc-version="1.0.1-node: 27be064e090742359bbdd1914f9d7dd363c8e0d8" \
no-quorum-policy="ignore" \
stonith-enabled="false" \
default-resource-stickiness="1000"
And if i exit crm and enter again i get:
alpha:/ # crm
crm(live)# configure
ERROR: syntax : order mysql_after_drbd INFINITY:
crm(live)configure# show
ERROR: object mysql_after_drbd cannot be represented in the CLI notation
crm(live)configure#
I'm attaching my log.
Thanks.
