"TypedDict" is new to standard python in 3.8 so I imagine this is a python version thing On Wed, Nov 19, 2025 at 12:28 PM Neha Ojha <nojha@redhat.com> wrote:

Hi,
on one of my test clusters the upgrade from 19.2.3 to 20.2.0 failed, I didn't look too deep into that since it's a single node cluster. So I decided to bootstrap a fresh cluster:
soc9-ceph:~ # cephadm --image quay.io/ceph/ceph:v20.2.0 bootstrap --mon-ip 192.168.124.186 --single-host-defaults --allow-mismatched-release --skip-firewalld --allow-overwrite --skip-monitoring
There's no error in the terminal output, the bootstrap command finishes successfully (including adding hosts). But when I tried to add OSDs, I noticed that the host is not present:
soc9-ceph:~ # ceph orch host label add soc9-ceph osd host soc9-ceph does not exist

Maybe this doesn't work because of python3.6 or something, I don't really have the time to check right now, but the bootstrap itself should abort and show an error when some of the steps failed. Should I create a tracker for this?
yes, please (cc: Adam King)
Thanks, Neha

Zitat von Yuri Weinstein <yweinste@redhat.com>:
We're very happy to announce the first stable release of the Tentacle series.
We express our gratitude to all members of the Ceph community who contributed by proposing pull requests, testing this release, providing feedback, and offering valuable suggestions.
We would like to especially thank some of our community members who
us test upgrades for the pre-released version of 20.2.0. Your feedback and effort are greatly appreciated!
Note from the Ceph Infrastructure Team:
Part of our Standard Operating Procedure for Ceph releases is typically to upgrade the Ceph cluster in the Ceph lab to the latest version before announcing the release. This is a production cluster, which we colloquially call the Long Running Cluster (LRC), as it has existed and been updated for the past decade or even longer. For this release, we have decided to hold off on updating the LRC until we have migrated some of the labs from Red Hat data centers to IBM. We plan to update the LRC to Tentacle in the next calendar year. We believe this decision should not be viewed as a reflection of our confidence in the project, but rather as an attempt to focus on other priorities before
helped the
migration.
---Highlights---
CephFS
* Directories may now be configured with case-insensitive or normalized directory entry names. * Modifying the FS setting variable ``max_mds`` when a cluster is unhealthy now requires users to pass the confirmation flag (``--yes-i-really-mean-it``). * ``EOPNOTSUPP`` (Operation not supported) is now returned by the CephFS FUSE client for ``fallocate`` for the default case (i.e. ``mode == 0``).
Crimson
* SeaStore Tech Preview: SeaStore object store is now deployable alongside Crimson-OSD, mainly for early testing and experimentation. Community feedback is encouraged to help with future improvements.
Dashboard
* Support has been added for NVMe/TCP gateway groups and multiple namespaces, multi-cluster management, OAuth 2.0 integration, and enhanced RGW/SMB features including multi-site automation, tiering, policies, lifecycles, notifications, and granular replication.
Integrated SMB support
* Ceph clusters now offer an SMB Manager module that works like the existing NFS subsystem. The new SMB support allows the Ceph cluster to automatically create Samba-backed SMB file shares connected to CephFS. The ``smb`` module can configure both basic Active Directory domain or standalone user authentication. The Ceph cluster can host one or more virtual SMB clusters which can be truly clustered using Samba's CTDB technology. The ``smb`` module requires a cephadm-enabled Ceph cluster and deploys container images provided by the ``samba-container`` project. The Ceph dashboard can be used to configure SMB clusters and shares. A new ``cephfs-proxy`` daemon is automatically deployed to improve scalability and memory usage when connecting Samba to CephFS.
MGR
* Users now have the ability to force-disable always-on modules. * The ``restful`` and ``zabbix`` modules (deprecated since 2020) have been officially removed.
RADOS
* FastEC: Long-anticipated performance and space amplification optimizations are added for erasure-coded pools. * BlueStore: Improved compression and a new, faster WAL (write-ahead-log). * Data Availability Score: Users can now track a data availability score for each pool in their cluster. * OMAP: All components have been switched to the faster OMAP iteration interface, which improves RGW bucket listing and scrub operations.
RBD
* New live migration features: RBD images can now be instantly imported from another Ceph cluster (native format) or from a wide variety of external sources/formats. * There is now support for RBD namespace remapping while mirroring between Ceph clusters. * Several commands related to group and group snap info were added or improved, and ``rbd device map`` command now defaults to ``msgr2``.
RGW
* Added support for S3 ``GetObjectAttributes``. * For compatibility with AWS S3, ``LastModified`` timestamps are now truncated to the second. Note that during upgrade, users may observe these timestamps moving backwards as a result. * Bucket resharding now does most of its processing before it starts to block write operations. This should significantly reduce the client-visible impact of resharding on large buckets. * The User Account feature introduced in Squid provides first-class support for IAM APIs and policy. Our preliminary STS support was based on tenants, and exposed some IAM APIs to admins only. This tenant-level IAM functionality is now deprecated in favor of accounts. While we'll continue to support the tenant feature itself for namespace isolation, the following features will be removed no sooner than the V release: - Tenant-level IAM APIs including CreateRole, PutRolePolicy and PutUserPolicy, - Use of tenant names instead of accounts in IAM policy documents, - Interpretation of IAM policy without cross-account policy evaluation, - S3 API support for cross-tenant names such as `Bucket='tenant:bucketname'` - STS Lite and `sts:GetSessionToken`.
