That is plausible since I am using single-process client and server. Is there a way to tell on a running glfs cluster which node is the current lock master? The process creating the load was running on the first listed volume, so I would have expected this to be the primary lock server.

The rule for lock servers is:

Lock servers = {The first n subvolumes of replicate that are up}

where n is given by the options "data-lock-server-count", "metadata-lock-server-count",
and "entry-lock-server-count", which all default to 1.

All the n lock servers in this set will be identical in their state.
