`gluster volume set help`  lists many of the documented options. For the 
others (which  usually are not needed to be tweaked but its there if you 
still want to play with), each translator has a*struct volume_options 
options[]* in the source code (do agit grep "struct volume_options 
options" on the source code) which usually has a ".*description*" filed 
that gives a short description.

HTH,

Ravi
