[root@platform test]# gluster volume info

I see that Brick1 is NULL not sure why it is null since i have entries. 

[root@platform test]# ls -l /etc/glusterd/vols/test/

This bug is the result of not raising errors when retrieving the glusterd-store for the brick is corrupted. Ideally if there are errors in retrieving the glusterd-store, glusterd should exit giving the error, which is done as part of 2066. This corruption happened because of the bugs in glusterd-store which is fixed as part of 1754. So closing this bug
