If that is the case, then is it safe to assume that fs_sb_format will
always be bytes 0x1001a and 0x100b on a gfs logical volume, and that that 
is the only location on the lv that it is stored?  I see 
#define GFS_FORMAT_FS (1309) /* Filesystem (all-encompassing) */
and that is the location that where I see 0x051d (1309) stored.
