[NTLUG:Discuss] Which filesystem & partitioning for a 9Terabyte volume?

[Richard]

OK.. so I have a situation where I'll be needing to setup a 9 terabyte 
RAID-5 array to host filespace for some OSX/Mac files.  The last time I 
did something similar I was unable to partition the 4.1T volume and 
wound up using LVM  to create a ReiserFS on the device -- NOT PARTITION.

The issue I've had doing it that way is that to the untrained person 
there is all this unallocated space!  No partitions...just lots of 
unallocated space!   Of course that's not true as one can put a 
filesystem on /dev/sdb as easily as /dev/sdb1.

So what should I do now with eight 1.5TB drives and an 8-port 3ware 
controller (and either Slackware 12.2 or OpenSuse 11.1)?
