Hi all
I have a drbd backed mysql server which has the following resources:
drbd0 -> lvm_data -> mount_data
drbd1 -> lvm_logs -> mount_logs
mysqld
floatingip
I would like the drbd based filesystems to start up in parallel. Once
they have started, start mysql and the ip address. Obviously the reverse
should happen on standby or shutdown.
I currently have the following configured
colocation IP_with_mysql inf: FloatingIP group_mysql
colocation all_drbd inf: ms_drbd1:Master ms_drbd0:Master
colocation colo-data inf: group_mysql group_logs
colocation colo-logs inf: group_mysql group_data
colocation mysql_on_drbd0 inf: group_data ms_drbd0:Master
colocation mysql_on_drbd1 inf: group_logs ms_drbd1:Master
order order_data_0 inf: ms_drbd0:promote group_data:start
order order_data_1 inf: group_data:start group_mysql:start
order order_data_2 inf: group_data:start FloatingIP:start
order order_logs_0 inf: ms_drbd1:promote group_logs:start
order order_logs_1 inf: group_logs:start group_mysql:start
order order_logs_2 inf: group_logs:start FloatingIP:start
This works fine on startup and shutdown, but if I do a crm resource
migrate MySQL, the active node shuts down the MySQL resource, but never
releases the drbd masters or dependant resources

Is there a better/more concise/more correct way of specifying the
colocations and orderings?
