Seriously start looking at FCP storage, at least for data partitions. While I really like the ability to manage minidisks, you need to be able to hand out bigger chunks, and LVM is just too much of a PITA long term to use to assemble really large chunks of disk (> a few hundred G).
In the interim, set up LVM groups of mod 54s and stripe across them. Find a (small, medium,large) increment and offer the ability to hand out increments of the "standard" unit (50-100G is probably a good number in most cases). ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to lists...@vm.marist.edu with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
