I have a server setup with a RAID 5 using (3) 500GB drives, 1 as a spare so unused in the RAID. So in my mind i start out with 990GB with the RAID 5 in place. When looking at DF or the built in disk space utility i only see a total of about 882GB, how can i find where the 100+GB went? How can i get it back?
I've checked the RAID 5 BIOS and i see all the space.
I've tried looking manually and through terminal commands with no luck.

More info for you, i am now positive i am not getting all my GB's

After the above info i found through lvm and vgs, i already figured out that i have all my space accounted for
df -k
? TomTom's answer below is an excellent one, but there may be another factor or two in play.df
will do for me. But it would be useful to know what model drives they are.
