[Linux-HA] Trying to understand: resource cant run anywhere

[Dave Augustus]

Hello all,

I setup my cluster (2 nodes) with 15 ip addresses and one application
resource (sshd). I went home and all was fine. I came in this morning
and the sshd had errored on both hosts and neither host was running any
resources. Of course, my logging told me that each resource *can't run
anywhere* . 
So today I cleaned up the erorrs with:

crm_resource -C -r resource_sshd -H mynode1
crm_resource -C -r resource_sshd -H mynode2

and all the resources came online including the ssh resource.

Now, I am trying to grasp what occurred. Is the following true?

-sshd errored out at least once on both nodes and so ALL the resources
went offline permanently until I cleaned them up.

If my understanding is correct, how do I correct this problem?
What log tells me more details about WHY the sshd resource failed?

Thanks,
Dave
