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 were 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 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.
