|
- *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

12.2.1
|
|
------
|
|
|
|
- *RGW*
|
|
|
|
* dynamic resharding is now enabled by default, RGW will now automatically
|
|
reshard the bucket index once the index grows beyond `rgw_max_objs_per_shard`
|
|
|
|
- *CephFS*:
|
|
|
|
* Limiting MDS cache via a memory limit is now supported using the new
|
|
mds_cache_memory_limit config option (1GB by default). A cache reservation
|
|
can also be specified using mds_cache_reservation as a percentage of the
|
|
limit (5% by default). Limits by inode count are still supported using
|
|
mds_cache_size. Setting mds_cache_size to 0 (the default) disables the
|
|
inode limit.
|
|
|
|
* The maximum number of PGs per OSD before the monitor issues a
|
|
warning has been reduced from 300 to 200 PGs. 200 is still twice
|
|
the generally recommended target of 100 PGs per OSD. This limit can
|
|
be adjusted via the ``mon_max_pg_per_osd`` option on the
|
|
monitors. The older ``mon_pg_warn_max_per_osd`` option has been removed.
|
|
|
|
* Creating pools or adjusting pg_num will now fail if the change would
|
|
make the number of PGs per OSD exceed the configured
|
|
``mon_max_pg_per_osd`` limit. The option can be adjusted if it
|
|
is really necessary to create a pool with more PGs.
|
|
|
|
* There was a bug in the PG mapping behavior of the new *upmap*
|
|
feature. If you made use of this feature (e.g., via the `ceph osd
|
|
pg-upmap-items` command), we recommend that all mappings be removed (via
|
|
the `ceph osd rm-pg-upmap-items` command) before upgrading to this
|
|
point release.
|
|
|
|
13.0.0
|
|
------
|
|
|
|
* 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.
