create single partition for 3.5 TB

[Carl Fischer]

Dave,
   Your configuration is nearly identical to our old one.  We started with
two partitions: an 80 GB install partition and a (3.5 TB - 80 GB =) 3.5 TB
ext3 partition.  EXT3 performs quite poorly on such large disks -- requiring
huge volumes of RAM for fsck.  We have 16 GB of RAM and it ran very slowly.
   When we expanded to a 16 GB partition (by adding some MD-1000's), I found
ext3 to be completely incapable.  ext3 resize worked, but things behaved
strange and 16 GB of RAM was insufficient to run fsck to correct it.  We've
since switched that partition to XFS and things have been just fine ever
since (with the unrelated exception of a firmware crash on the PERC 5E
during rebuild after a disk failed).
