[DRBD-user] drbdmanage hangs frequently

I have a small cluster used for Openstack (Newton on centos 7 nodes). I have 2 
main storage nodes, 1 openstack controller node and 5 'diskless' hypervisors. 
It's configured with the hypervisors as satellite nodes and the 3 remaining 
servers as management nodes with the management volume, though only the 2 
storage nodes actually hold the rest of the user data.

I'm finding that drbdmanage hangs frequently trying to communicate with the 
service. Even 'drbdmanage ping' will timeout. Examining the service process I 
see it apparently busy connecting to another host which is itself hung.

Any ideas what's wrong or what troubleshooting steps I should be taking here?


drbdmanage version 0.99.14
kernel driver version 9.0.9
drbd-utils version 9.1.1
all built from source tarballs
