Hi. I am having a problem whilst carrying out some preliminary
testing of DRBD with OpenAIS. My test setup was all working fine. I
have now introduced it to a simulated wide area network by changing the
subnet on each system, modifying the config files accordingly, adding
the relevant routes and gateway, and using an established Linux box that
we use for throttling bandwidth for such testing. The network config is
sound as I can ping to and from each node through the router system. I
also have full key authentication setup between them. Nothing else has
changed.
Now, the DRBD nodes are failing to sync. I am getting no obvious errors.
If I watch the /proc/drbd file, it goes through the motion of syncing,
and the progress bar briefly is seen. It then flips back.
Below is a typical output of cat /proc/drbd ran one after the other. It
just goes on and on like this, and never actually syncs.
Any ideas? I have pasted the relevant parts of my config files further
below.
Thanks
Gary
