Other than the usual putting all your eggs into one basket problem,
why should a lun over 2TB containing an ext3 file system, be any
more risky than those under 2TB, assuming all the partition table
issues are resolved? Are there performance, reliability,
compatibility, or other problems?

(I'm not saying you're wrong but I'm always suspicious of claims
like these without specific examples of why something is a bad
idea.)

Cordially,
