[Ceph-announce] v14.2.17 Nautilus released

Body: We're happy to announce the 17th backport release in the Nautilus 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/releases/v14-2-17-nautilus-released Notable Changes --------------- * $pid expansion in config paths like `admin_socket` will now properly expand to the daemon pid for commands like `ceph-mds` or `ceph-osd`. Previously only `ceph-fuse`/`rbd-nbd` expanded `$pid` with the actual daemon pid. * RADOS: PG removal has been optimized in this release. * RADOS: Memory allocations are tracked in finer detail in BlueStore and displayed as a part of the ``dump_mempools`` command. * cephfs: clients which acquire capabilities too quickly are throttled to prevent instability. See new config option ``mds_session_cap_acquisition_throttle`` to control this behavior. Getting Ceph ------------ * Git at git://github.com/ceph/ceph.git * Tarball at http://download.ceph.com/tarballs/ceph-14.2.17.tar.gz * For packages, see http://docs.ceph.com/docs/master/install/get-packages/ * Release git sha1: 2e95b5d99e0dec516803c8a1b57fbd2c8f45fd63
