Hi John,
Thanks for this info. Drobo says no ext4: http://support.drobo.com/app/answers/detail/a_id/165/~/how-do-i-use-my-drobo...
I will look up XFS.
Jason

here's my parted recipe for making very large volumes... this will fill the disk, reserving 512K up front to be on a reasonable stripe boundary

I would under NO conditions make a EXT3 volume anywheres NEAR as big as you're talking about. my preference for large volumes is XFS.
VG=vg_$(hostname -s)_data vgcreate $VG /dev/sdb1 lvcreate --size 8T --name lv_data $VG mkfs.xfs /dev/$VG/lv_data mount /dev/$VG/lv_data /dataif your storage device presents the storage as a block device, then there's no 'support' issues I'm aware of for file systems, its just sectors as far as the storage device is concerned, the file system is strictly up to your OS.
