David, thanks for your answer!
I'll try to migrate to corosync.

Hi, list!
I have configured cluster for voip application.
Here my configuration:
# crm configure show
node $id="552f91eb-e70a-40a5-ac43-cb16e063fdba" freeswitch1 \
attributes standby="off"
Ah... right here is your problem. You are using freeswitch instead of Asterisk
:P
node $id="c86ab64d-26c4-4595-aa32-bf9d18f714e7" freeswitch2 \
attributes standby="off"
primitive FailoverIP1 ocf:heartbeat:IPaddr2 \
params iflabel="FoIP1" ip="91.211.219.142" cidr_netmask="30"

When 1-st node was crashed, then 2-nd node become active. During this
process in ha-debug file I found lines:
...

After "Starting pengine", only thru 4 seconds occured next action.
What happens at this time? Is it possible to reduce this time?
I seem to remember seeing something related to this in the code at one point.
I believe it is limited only to the use of heartbeat as the messaging layer.
After starting the pengine, the crmd sleeps waiting for the pengine to start
before contacting it. The sleep is just a guess at how long it will take
before the pengine will be up and ready to accept a connection though. That's
why it is so long... so the gap will hopefully be large enough that no one will
ever run into any problems with it (I am not a big fan of this type of logic at
all) I'd recommend moving to corosync and seeing if this delay goes away.

Thanks in advance.
