v16.2.5 Pacific released

We're happy to announce the 5th 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/v16-2-5-pacific-released Notable Changes --------------- * `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. * mgr/nfs: `nfs` module is moved out of volumes plugin. Prior using the `ceph nfs` commands, `nfs` mgr module must be enabled. * volumes/nfs: The `cephfs` cluster type has been removed from the `nfs cluster create` subcommand. Clusters deployed by cephadm can support an NFS export of both `rgw` and `cephfs` from a single NFS cluster instance. * The `nfs cluster update` command has been removed. You can modify the placement of an existing NFS service (and/or its associated ingress service) using `orch ls --export` and `orch apply -i ...`. * The `orch apply nfs` command no longer requires a pool or namespace argument. We strongly encourage users to use the defaults so that the `nfs cluster ls` and related commands will work properly. * The `nfs cluster delete` and `nfs export delete` commands are deprecated and will be removed in a future release. Please use `nfs cluster rm` and `nfs export rm` instead. * A long-standing bug that prevented 32-bit and 64-bit client/server interoperability under msgr v2 has been fixed. In particular, mixing armv7l (armhf) and x86_64 or aarch64 servers in the same cluster now works.
