Hello,  
We have a cluster second node join problem.  
In log we se the following error:

Marking file as dirty: /etc/corosync/corosync.conf

As far as I see the main problem is:  
The hash size used in signature (32) is less than the expected (48)  
Please advice how to solve this problem.  
Thank you
