I hope this is the right list as there are several that seem related. If not,
please excuse this and direct me to the correct list.
I am attempting to setup an active/passive NFS cluster with DRBD and OpenAIS.
The two nodes are nfsserver1 and nfsserver2 and I have everything setup. The
problem I'm having is it seems that
only nfsserver2 functions properly. If I take nfsserver2 offline, (crm node
standby, or just shutdown or whatever) I get failures attempting to to export
the filesystems.
The odd thing is, it says nfsserver2 that is failing (rather than nfsserver1
which it should be mounting on) and sets the export as (unmanaged). Bringing
nfsserver2 back online does not fix it. I have to run "crm_resource -r
p_exportfs_nfsshares -C -H nfsserver2" to correct the problem and get things
running on nfsserver2 again.
I am running these servers on Fedora 14.
This is my config:

This is what it looks like when nfsserver2 is functioning:

Is there something I have mis-configured?
