The brick directory will have some xattrs while being part of the volume.
So you will have to remove the xattrs from the directory before adding the
brick to the volume again. You can simply delete the directory and
re-create it again.

Since you have replica 2 volume, you should add/remove at least 2 bricks at
a time. You can try the following (after you delete and re-create
gwgfs02:/data/brick1/vol01)
gluster volume add-brick vol01 gwgfs02:/data/brick1/vol01
gwgfs03:/data/brick1/vol01
