Description Raghavendra Bhat 2011-10-03 01:46:48 EDT
4 peer cluster. a replicate volume with 2 bricks (i.e. replica count 2).

volume status <volname> command on the peers which have bricks running crahes one of the glusterd's if the volume status command is issued alternatively on those peers.

This is the backtrace.

Core was generated by `glusterd -LDEBUG'.
Program terminated with signal 6, Aborted.
