The video and meeting notes are now available: https://www.youtube.com/watch?v=3DltIIDDq9qag&feature=3Dyoutu.be - ZoL + SIMD + Linux 5.0 (Matt) - Brian integrated some support for this already but he is currently on vacation - 5.0+ made some changes to the floating point registers that were used by ZoL for SIMD instructions - Brian reimplemented some of those in ZoL and now these instructions work again and will be backported in 0.8 - Needed for performant RAIDZ, Encryption, and some compression algorithms - Used only if the underlying CPU architecture actually supported (checked during runtime) - OpenZFS Developer Summit (Matt) - Announced: Nov 4-5. Same locations as last year in SF. - Registration and call for papers is open. Please submit a talk and tell us about the cool stuff you=E2=80=99re doing with ZFS - We appreciate people volunteering to help out with things for the conference. - Karyn will reach out to Rainbow about help with AV. - Ticket prices went up to $100. There are some discount tickets available, and let us know if the pricing is a hardship and we can tr= y to figure something out. - FreeBSD Foundation may have travel grants available if want to apply - Get all the details (including a link to the registration site) on the OpenZFS wiki page <http://open-zfs.org/wiki/OpenZFS_Developer_Summit_2019> - Property to track amount of queued TRIM/UNMAP (like =E2=80=9Cfreeing=E2= =80=9D for async destroy) (Allan) - Allan Jude: users may want to know how many trim/unmapped is left or in-progress before performing other actions instead of performing the= pool - Matt: Maybe a flag to zpool sync =E2=80=94trim that could wait for al= l trim activity to be done. Probably better than the existing proposal where= we have a property like freeing for it, which would jump up and down - `zpool wait` that is about to be upstreamed from Delphix and should be a good candidate to add this functionality. You can look at the Delphix repo if you want to see it before the PR. - RAIDZ removal issue <https://github.com/zfsonlinux/zfs/issues/9013> with design ideas (Igor) - RAIDZ expansion progress (Matt) - No progress to report since preview posted - The hope is to have takers to test it out - The functionality is there, there are on-disk format changes (so don't use it in production), a few race conditions being fixed and so= me more error handling for device failures. - Important to note that even though we can expand the RAIDZ we still can't remove devices (e.g. zpool remove) - ZoL PR exists <https://github.com/zfsonlinux/zfs/pull/8853> with design considerations for the feature - OpenZFS feature matrix <https://docs.google.com/spreadsheets/d/1CFapSYxA5QRFYy5k6ge3FutU7zbAWba= eGN2nKVXgxCI/edit?usp=3Dsharing> (everyone) - FreeBSD is hoping to catch up with ZoL through the ZoF work - NFSv4 ACL PR waiting for code review - should we consider tracking this in the feature Matrix? - Update: Added - Note: already on illumos On Mon, Jul 22, 2019 at 1:03 PM Matthew Ahrens <mahrens@delphix.com> wrote: > The next OpenZFS Leadership meeting will be held tomorrow, July 23, > 11am-noon Pacific time. > > Everyone is welcome to attend and participate, and we will try to keep th= e > meeting on agenda and on time.
