So is btrfs ready for production -- all the tools work, etc. to the level that the ext2/3/4 work? Also, what kernel do you need for this to function -- and last question, how to convert an lvm volume to btrfs, or do you just have to make some space somewhere and copy the files? So far, I have liked lvm, what's the advantage of btrfs over lvm? -- Your life is like a penny. You're going to lose it. The question is: How do you spend it? John Covici cov...@ccs.covici.com
