Description krishnan parthasarathi 2011-08-03 11:35:03 UTC

This bug tracks the following changes,

- removal of glusterd's local cli lock and use the cluster wide lock to serialize
  concurrent cli requests to the same glusterd.

- improve glusterd's internal cluster-wide locking mechanism when multiple clients request operations via multiple glusterds.

Its fixed now. Checked with glusterfs-3.3.0qa10. Now parallel cli operations will make only one of them succeed, and glusterd wont crash.
