What exactly do you mean by CephFS cloning ? This cluster is used exclusively to provide RWX volumes to a k8s using cephcsi. Velero does backup though and creates volume snapshots , but I am not sure if that's what you mean. Any commands I can run to confirm if cloning is being used ?
[Afreen] Yes that confirms then . So this bugs is being fixed and it only happens with cephfs subvolums die to a wrong format internally used https://tracker.ceph.com/issues/75619

"ceph progress clear" did the trick to load the pools page in the
dashboard, but you said: "Its just clears the display events and does not stop operations." What operations are still running ? post-upgrade operations? why? Will them eventually finish ?
[Afreen] What I meant was that running that command was not harmful. And good to know it worked for you.
Thanks
Thanks!

Hey,
That seems like some issue in parsing the format and so far what we
And pools page is failing because its polling /summary API - fetching
found out is that it could happen when CephFS cloning is used , are you using that ? progress internally.
You can try clearing progress and then refresh - "ceph progress clear".
Its just clears the display events and does not stop operations.

After upgrading from 20.2.2 to 20.2.3, the dashboard is partially broken. List pools don't work. Error 500. Also get error 500 popup as soon as I login to the dashboard.

This is the third minor release in the Tentacle series. We recommend that all users update to this release.
Notable Changes ---------------
MDS (Metadata Server) ---------------------
* Fixed a crash and shutdown hang that could occur when ephemeral
active and max_mds was set to 0. * Session reclaim could miss blocklisting an old session; this is now handled correctly. * Fixed a case where scrub was unable to identify damage from an irreparable hard link.
OSD (Object Storage Daemon) ----------------------------
* BlueStore: Fixed a BlueFS WAL envelope-mode bug that caused write buffer misalignment. * Erasure Coding: Fixed truncate+write planning for EC shard sizes. * Fixed a condition that prevented rolling forward of PG log entries. * Prevented OSDMap::check_health() from asserting when new OSDs are found in a subtree. * Scrub: "repairing" scrubs are now allowed at all times.
RGW (RADOS Gateway) --------------------
* Added the ssl_ciphersuites option for the Beast front-end to support TLS 1.3 cipher customization. * Fixed PutObject's canned_acl comparison bug affecting BlockPublicAcls. * Fixed crashes occurring on realm reload. * Implemented CopyObject support for encrypted objects. * Added mTLS client-certificate authentication support for Kafka notifications. * Fixed removal of delete markers in lifecycle processing.
RADOS / librados / neorados ----------------------------
* neorados: Fixed an infinite trim loop on empty data log shards. * Fixed cancellation-slot cleanup in librados/asio's associated executor.
Dashboard -----------------
* Added a hardware-monitoring dashboard backed by node-proxy metrics. * Fixed a bind-address regression caused by CherryPy isolation. * Added support for adding hosts via CSV upload. * NVMeoF: multiple CLI and UI backports (EC pool support, IO statistics, role management). * Object: The global RGW Roles tab has been removed. Role management is now scoped under RGW Accounts, where roles can be listed, created, edited, and deleted for a selected account.
ceph-volume -----------
* Reworked OSD mapper lifecycle handling (LVM + raw) for activate. * Improved detection of rotational media under dm-crypt to bypass the workqueue correctly. * Fixed OSD re-deployment issues with disk-selection filters and DB devices. * Added retry handling for lvs when it returns an empty result or a "devices file is missing" error.
NVMe-oF -------
* Added configurable delayed failback (default 0, no delay) to accommodate initiators that recover paths with a delay. * Gateways in the DELETING state now ignore beacons and send empty maps instead of processing them. * rbd_with_crc32c is now enabled by default via cephadm. * Introduced a new NVMeoF mgr module. The module automatically creates the ".nvmeof" metadata pool if it does not already exist. Gateway-group state files are stored in this pool unless the user specifies another
ceph-users@ceph.io> wrote: pins were pool. The
module is enabled automatically on fresh installs; on upgrades from an older cluster, it must be enabled manually.
RBD ---
* Fixed a use-after-free bug releasing object map locks during deep copy. * Fixed memory leaks in PWL discard operations. * Obsolete primary mirror snapshots are now pruned after relocation.
We recommend users to update to this release. For detailed release notes with links & changelog please refer to the official blog entry at https://ceph.io/en/news/blog/2026/v20-2-3-tentacle-released/
