Message: 3 Date: Thu, 16 Sep 2021 15:48:42 -0400 From: David Galloway <dgallowa@xxxxxxxxxx> Subject: v16.2.6 Pacific released To: ceph-announce@xxxxxxx, ceph-users@xxxxxxx, dev@xxxxxxx, ceph-maintainers@xxxxxxx Message-ID: <1d402d62-5b3e-b62e-c68c-3fb2b30f1a02@xxxxxxxxxx> Content-Type: text/plain; charset=utf-8 We're happy to announce the 6th backport release in the Pacific series. We recommend users to update to this release. For a detailed release notes with links & changelog please refer to the official blog entry at https://ceph.io/en/news/blog/2021/v16-2-6-pacific-released Notable Changes --------------- * MGR: The pg_autoscaler has a new default 'scale-down' profile which provides more performance from the start for new pools (for newly created clusters). Existing clusters will retain the old behavior, now called the 'scale-up' profile. For more details, see: https://docs.ceph.com/en/latest/rados/operations/placement-groups/ * CephFS: the upgrade procedure for CephFS is now simpler. It is no longer necessary to stop all MDS before upgrading the sole active MDS. After disabling standby-replay, reducing max_mds to 1, and waiting for the file systems to become stable (each fs with 1 active and 0 stopping daemons), a rolling upgrade of all MDS daemons can be performed. * Dashboard: now allows users to set up and display a custom message (MOTD, warning, etc.) in a sticky banner at the top of the page. For more details, see: https://docs.ceph.com/en/pacific/mgr/dashboard/#message-of-the-day-motd * Several fixes in BlueStore, including a fix for the deferred write regression, which led to excessive RocksDB flushes and compactions. Previously, when bluestore_prefer_deferred_size_hdd was equal to or more than bluestore_max_blob_size_hdd (both set to 64K), all the data was deferred, which led to increased consumption of the column family used to store deferred writes in RocksDB. Now, the bluestore_prefer_deferred_size parameter independently controls deferred writes, and only writes smaller than this size use the deferred write path. * The default value of osd_client_message_cap has been set to 256, to provide better flow control by limiting maximum number of in-flight client requests. * PGs no longer show a active+clean+scrubbing+deep+repair state when osd_scrub_auto_repair is set to true, for regular deep-scrubs with no repair required. * ceph-mgr-modules-core debian package does not recommend ceph-mgr-rook anymore. As the latter depends on python3-numpy which cannot be imported in different Python sub-interpreters multi-times if the version of python3-numpy is older than 1.19. Since apt-get installs the Recommends packages by default, ceph-mgr-rook was always installed along with ceph-mgr debian package as an indirect dependency. If your workflow depends on this behavior, you might want to install ceph-mgr-rook separately. * This is the first release built for Debian Bullseye. Getting Ceph ------------ * Git at git://github.com/ceph/ceph.git * Tarball at https://download.ceph.com/tarballs/ceph-16.2.6.tar.gz * Containers at https://hub.docker.com/r/ceph/ceph/tags?name=v16.2.6 * For packages, see https://docs.ceph.com/docs/master/install/get-packages/ * Release git sha1: ee28fb57e47e9f88813e24bbf4c14496ca299d31 ------------------------------
