Why is the addition of bricks to a Gluster volume failing?
Issue
During a standard operation to add a new set of bricks, the command fails with a generic error:
gluster volume add-brick test-vol replica 3 arbiter 1 host1:/gluster_bricks/brick1/brick host2:/gluster_bricks/brick2/brick host3:/gluster_bricks/brick1/arbiter FAILED : Commit failed on localhost. Please check log file for details.
