The commit was tagged for MFC, so if there are no stopper issues I am going to commit it to stable/8 in 2 months from today. Here is a short summary of what we gained with this update: 1. Stability - more mature ZFS code, comparable to Solaris 10 update 8 with latest bugfixes 2. Compatibility - Solaris 10 update 8 default ZFS pools can now be imported into FreeBSD 3. Features - user and group quotas (ZFS-internal) are very useful for intranet fileservers that want to use ZFS 4. Speed - my real-world benchmarks give a 15-20% RPS yield in PHP webserver workloads with codebase on ZFS I would like to thank everybody who helped testing the upgrade before it got commited. For the future, it would be very nice to reply not only to my e-mail but to the mailing list, too, so we can share the experience with others. For people interested in running this on 8.1 I will provide patches for releng/8.1 and stable/8 as soon as 8.1 gets released. Feel free to test everything and don't forget to report any bugs found. Cheers, mm
