------
|
|
|
|
* *CephFS*:
|
|
|
|
* Several "ceph mds" commands have been obsoleted and replaced
|
|
by equivalent "ceph fs" commands:
|
|
- mds dump -> fs dump
|
|
- mds getmap -> fs dump
|
|
- mds stop -> mds deactivate
|
|
- mds set_max_mds -> fs set max_mds
|
|
- mds set -> fs set
|
|
- mds cluster_down -> fs set cluster_down true
|
|
- mds cluster_up -> fs set cluster_down false
|
|
- mds add_data_pool -> fs add_data_pool
|
|
- mds remove_data_pool -> fs rm_data_pool
|
|
- mds rm_data_pool -> fs rm_data_pool
|
|
|
|
* New CephFS file system attributes session_timeout and session_autoclose
|
|
are configurable via `ceph fs set`. The MDS config options
|
|
mds_session_timeout, mds_session_autoclose, and mds_max_file_size are now
|
|
obsolete.
|
|
|
|
* *RBD*
|
|
|
|
* The RBD C API's rbd_discard method now enforces a maximum length of
|
|
2GB to match the C++ API's Image::discard method. This restriction
|
|
prevents overflow of the result code.
|
|
|
|
* The rbd CLI's "lock list" JSON and XML output has changed.
|
|
|
|
* The rbd CLI's "showmapped" JSON and XML output has changed.
|
|
|
|
* RBD now optionally supports simplified image clone semantics where
|
|
non-protected snapshots can be cloned; and snapshots with linked clones
|
|
can be removed and the space automatically reclaimed once all remaining
|
|
linked clones are detached. This feature is enabled by default if
|
|
the OSD "require-min-compat-client" flag is set to mimic or later; or can be
|
|
overridden via the "rbd_default_clone_format" configuration option.
|
|
|
|
* The sample ``crush-location-hook`` script has been removed. Its output is
|
|
equivalent to the built-in default behavior, so it has been replaced with an
|
|
example in the CRUSH documentation.
|
|
|
|
* The "rcceph" script (systemd/ceph in the source code tree, shipped as
|
|
/usr/sbin/rcceph in the ceph-base package for CentOS and SUSE) has been
|
|
dropped. This script was used to perform admin operations (start, stop,
|
|
restart, etc.) on all OSD and/or MON daemons running on a given machine.
|
|
This functionality is provided by the systemd target units (ceph-osd.target,
|
|
ceph-mon.target, etc.).
|
|
|
|
* The python-ceph-compat package is declared deprecated, and will be dropped
|
|
when all supported distros have completed the move to Python 3. It has
|
|
already been dropped from those supported distros where Python 3 is standard
|
|
and Python 2 is optional (currently only SUSE).
|
|
|
|
>= 12.2.2
|
|
---------
|
|
|
|
- *CephFS*:
|
|
|
|
* The CephFS client now catches failures to clear dentries during startup
|
|
and refuses to start as consistency and untrimmable cache issues may
|
|
develop. The new option client_die_on_failed_dentry_invalidate (default:
|
|
true) may be turned off to allow the client to proceed (dangerous!).
