I didn't. --clip-- Btrfs is in so early development that I don't know yet what to say about it, but the fact of ZFS's being incompatible with GPL might be mitigated by this. --clip-- > I have adminned a half-dozen UNIX variants professionally but > keep running into admins who only do ONE and for whom every > problem is solved with "how can I do this with one OS only?" So have I. But in the current Cyrus installation, I'm stuck with Linux, so I concentrated on what's available on Linux. Moreover, I don't want to use non-free operating systems - if anything, I've become more ideological with age...

Really? Btrfs /does/ appear promising to me. I might be wrong, though. > So far ZFS ticking along with no problems and low iostat numbers > with everything in one big pool.
