Added automated ABI validation for public library interfaces.Renamed acltype=posixacl to acltype=posix, an alias was added for compatibility.Support for memory and CPU hotplugging.Updated arcstat with new L2ARC statistics and added -a (all) and -p (parsable) command line options.Updated vdev_id to support daisy-chained JBODs in multipath mode.Extensive modernization of the man pages.InfluxDB Support - Collect pool statistics with the zpool influxdb command in an InfluxDB time-series database for analysis and monitoring.This fine grained control makes it easy to create portable pools and maintain pool compatibility between OpenZFS versions and across platforms. I think I'll start playing with it in scratch pool environments but the failure modes worry me a bit. At smaller scale, traditional vdevs and spares remain as useful as they ever were. Compatibility Property - The new compatibility property lets administrators specify the set of features which should be enabled on the pool. Distributed RAID vdevs are mostly intended for large storage serversOpenZFS draid design and testing revolved largely around 90-disk systems.OpenZFS 2.1.1 has around ninety fixes in this point release making it a rather hearty update from the big v2.1 feature release. Full redundancy can be restored to the pool in a fraction of the time normally required to do a full disk replacement. OpenZFS 2.1.1 also has data integrity fixes, various ZTS fixes, persistent L2ARC fixes, various FreeBSD-specific issues, several different optimizations, and dozens of other random fixes. Distributed Spare RAID (dRAID) - Create pools using a new distributed variant of RAIDZ which enables dramatically faster resilver times using integrated hot spares.FreeBSD: compatible with releases starting from 12.2-RELEASE.Linux: compatible with 3.10 - 5.13 kernels.You can follow the GitHub link below to see the huge list of bug fixes or to download OpenZFS 2.1. As a side note, Linux kernel 5.17 will be a long-term support version, and it will be removing the ReiserFS file system. On disk, ZFS DVA offsets are stored as (512-byte) blocks, but tools like zdb. Phoronix Premium allows ad-free access to the site, multi-page articles on a single page, and other features while. OpenZFS 2.1.3 also brings compatibility fixes for Linux kernel 5.17, which will be released in March 2022. See OpenZFS Developer Summit 2021 for presentations and information about last years (virtual) conference. See section 2.1.) Update: This turns out to be wrong (or a misunderstanding).
The previous version of OpenZFS supports only up to Linux kernel 5.15. OpenZFS 2.1.3 supports Linux kernel versions from 3.10 to 5.16. The new version of the OpenZFS implementation brings many bug fixes related to Linux compatibility, $KERNEL_ environment variables, pushover notifications support for Zed functions, and many more. The new version of OpenZFS supports up to kernel 5.16 but brings some compatibility fixes for 5.17 as well OpenZFS project is a fork of the original ZFS, and it is an open-source solution being developed by Matthew Ahrens. It provides many functionalities such as snapshots. Friday afternoon, the OpenZFS project released version 2.1.0 of our perennial favorite 'it's complicated but it's worth it' filesystem. The OpenZFS project is ongoing after Oracle acquired SunMicrosystems, the Zettabyte File System developer, in 2010. ZFS is a modern filesystem originally developed for SOLARIS. OpenZFS 2.1 is outlet’s talk about its brand-new dRAID vdevs dRAID vdevs resilver very quickly, using spare capacity rather than spare disks.
