Thanks to everyone who participated, and apologies for the delay in getting this posted.
video recording: https://youtu.be/6zb6AxL26d8 notes (thanks Serapheim): - Corrective Recv PR <https://github.com/openzfs/zfs/pull/9372> (Alek) - The functionality introduced here is for being able to “heal” a corrupted dataset from a send file (instead of deleting and recreating it). An interesting details is that this feature works regardless of the differences in the configuration of the target machine and the machine that generated the test file (e.g. compression or other properties). - Current status is that most of the tests are passing except a couple from the redacted send-receive tests in FreeBSD which cause a panic. - John Kennedy and Paul Dagnelie can help with this - Besides fixing the panic - the PR needs reviews. - Add Blake3 Checksum (PR <https://github.com/openzfs/zfs/pull/11897>) (Tino) - Currently experiencing problems with supporting this on FreeBSD. The complications seem specific to the code organization and getting the right directives in autoconf/automake and make to work. - Besides just adding this new checksump algorithm, the community would like to see how this algorithm compares to existing ones, running on a sufficiently modern CPU under different blocksizes. - Should I add sha_ni (x86) and maybe also aarch64 sha2 hardware support? - There is probably some low-hanging fruit for performance improvements, especially for our choice of CPU instructions. - Some support for this in FreeBSD has started being worked on: https://github.com/freebsd/freebsd-src/compare/main...allanjude:zfssha - Interface for /proc/spl/kstat/zfs/hashing_bench ? echo blake3-sse2 > hashing .. - ZFS and Linux Containers (LXD) (Allan Jude) - The idea here is jailing a dataset (group of datasets) to a user namespace in LXD. - In terms of code, this would mean at least implementing the IS_GLOBAL_ZONE() macro that currently in Linux always returns true. - Do people have interesting use/test cases? - If you do, please do reach out to Allan. - What makes sense for extending the ZTS to cover containers? - Besides the actual ZTS-specific additions, we’ll need to look at what we can reasonably add to our automated testing bots in Github to run those tests. - Cross-platform compatible xattr support (Alexander Motin - amotin) - Current status: There is progress but we’d love it if more people are able to look at the code and/or bring alternative solutions/ideas to the discussion. - ZFS on Object Storage - Currently an experiment within Delphix - The idea is to run ZFS on top of an object store like S3 or MinIO. - The focus is on performance for small record sizes. - There are currently two brand-new components being introduced: - A userland agent that facilitates the interaction between ZFS and the object store - A new block-based local cache introduced as a vdev type to improve the performance of the overall design of this project. - The L2ARC was briefly considered but it doesn’t satisfy the requirements for the current use-case as its memory requirements are high. - More technical details on the upcoming OpenZFS Summit. - Until then, while the technical requirements are still being designed we’d love any feedback on the administrative/user interface of this project. - Currently we just provide a couple of user properties just to test the design (e.g. a property for the s3 URL, credentials file, etc..). Eventually if we are to start supporting other protocols we’ll need to have a user interface and workflow that works for all of them.
