If you'll refer to my previous reply, 24007 (and maybe 24008) are the 
management daemon (glusterd) ports. The glusterfs client calls the 
management daemon for the volume configuration. Once retrieved, the 
client then connects to all of the bricks (glusterfsd) defined in that 
configuration. The brick ports vary depending on how many volumes exist 
and how many bricks but are within the range I specified previously.
