[ClusterLabs] Upgrade corosync problem

Hi Christine,

Thanks for reply. Let me add few details. When I run the corosync service I se the corosync process running. If I stop it and run:

corosync -f 

I see three warnings:
warning [MAIN  ] interface section bindnetaddr is used together with nodelist. Nodelist one is going to be used.
warning [MAIN  ] Please migrate config file to nodelist.
warning [MAIN  ] Could not set SCHED_RR at priority 99: Operation not permitted (1)
warning [MAIN  ] Could not set priority -2147483648: Permission denied (13)

but I see node joined.

My corosync.conf file is below.

With service corosync up and running I have the following output:
corosync-cfgtool -s
Printing ring status.
Local node ID 1
RING ID 0
	id	= 10.0.0.11
	status	= ring 0 active with no faults
RING ID 1
	id	= 192.168.0.11
	status	= ring 1 active with no faults

corosync-cmapctl  | grep members
runtime.totem.pg.mrp.srp.members.1.config_version (u64) = 0
runtime.totem.pg.mrp.srp.members.1.ip (str) = r(0) ip(10.0.0.11) r(1) ip(192.168.0.11) 
runtime.totem.pg.mrp.srp.members.1.join_count (u32) = 1
runtime.totem.pg.mrp.srp.members.1.status (str) = joined
runtime.totem.pg.mrp.srp.members.2.config_version (u64) = 0
runtime.totem.pg.mrp.srp.members.2.ip (str) = r(0) ip(10.0.0.12) r(1) ip(192.168.0.12) 
runtime.totem.pg.mrp.srp.members.2.join_count (u32) = 1
runtime.totem.pg.mrp.srp.members.2.status (str) = joined

For the moment I have two nodes in my cluster (third node and some issues and at the moment I did crm node standby on it).

Here the dependency I have installed for corosync (that works fine with pacemaker 1.1.14 and corosync 2.3.5):
     libnspr4-dev_2%253a4.10.10-0ubuntu0.14.04.1_amd64.deb
     libnspr4_2%253a4.10.10-0ubuntu0.14.04.1_amd64.deb

     libnss3_2%253a3.19.2.1-0ubuntu0.14.04.2_amd64.deb
     libqb-dev_0.16.0.real-1ubuntu4_amd64.deb
