It is not heartbeat or corosync specific, but depends on support
in the init script (/etc/init.d/corosync). The init script should
read the sysconfig file and then invoke lrmadmin to set the max

Just a reminder, but systemd unit files cannot do this.

Hi All,
I am using pacemaker 1.0.11 + corosync 1.4.2 for a 2 node cluster
I have configured one Group, which is having 12 resources,
Ordered parameter is set to false but all 12 resource are not started
parallel.
At a time only four resource started parallel.
This is probably the lrmd limit.
Resource 1,2,3,4 starts then 5,6,7,8 starts, then 9,10,11,12
If 5 second sleep is their in Resource-Agent's start method.
Then All the resources will start in 15 second.
Please can you suggest how can I solve the same,
It seems, only four thread starts at a time for a group's resource,

The old cib.xml for Heartbeat based cluster had an option
ordered=true | false for group tag which supported starting of
resources in series or parallel.
this meta attribute is still available ... when in crm shell add:
meta ordered=false
to your group resource ... or you could also use a colocation set.

By default, resources in Resource Group start in serial order for
Pacemaker based clusters.
Is there a way to start multiple resources in parallel?
