This is in fact a 120 TB (not GB) filesystem that I am trying to build.

What I am attempting to do is to take 80 1.6 TB arrays ((8 x 250 GB Raid
5 arrays) 10 arrays from 8 seperate SAN's). Use LVM to make one large
volume, then use xfs to format and mount this as a single filesystem.

Any advice - or gotcha's would be appreciated.
