Hey, That seems like some issue in parsing the format and so far what we found out is that it could happen when CephFS cloning is used , are you using that ? And pools page is failing because its polling /summary API - fetching progress internally. You can try clearing progress and then refresh - "ceph progress clear". Its just clears the display events and does not stop operations. - Afreen On Thu, Aug 6, 2026 at 6:42 PM Salatiel Filho via ceph-users < ceph-users@ceph.io> wrote:
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 pins
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
were the
".nvmeof" metadata pool if it does not already exist. Gateway-group state files are stored in this pool unless the user specifies another 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.
