I'm happy Ubuntu is exploring other file sytsem choices.Both file sizes and volume sizes will be pressing issues sooner than later.It seems crazy that I'd ever consider 16TB for files and 1EB a legitimate limitation (as in ext4). But I can see it quickly becoming a issue.I'd never thought much about de-fragmentation, till I had file sytsems with hundred of thousands of files, many larger than two gigs.Or that I would have volumes I needed to resize, with the expectation of *NO* downtime.Or even having a file server that by default has eight or sixteen cores, And that I could/should/need to leverage them, to improve performance.
