>= 11.0.0
------
* The list of monitor hosts/addresses for building the monmap can now be
obtained from DNS SRV records. The service name used in when querying the DNS
is defined in the "mon_dns_srv_name" config option, which defaults to
"ceph-mon".
* The 'osd class load list' config option is a list of object class names that
the OSD is permitted to load (or '*' for all classes). By default it
contains all existing in-tree classes for backwards compatibility.
* The 'osd class default list' config option is a list of object class names
(or '*' for all classes) that clients may invoke having only the '*', 'x',
'class-read', or 'class-write' capabilities. By default it contains all
existing in-tree classes for backwards compatibility. Invoking classes not
listed in 'osd class default list' requires a capability naming the class
(e.g. 'allow class foo').
* The 'rgw rest getusage op compat' config option allows you to dump the description of user stats
or not in s3 GetUsage API. This config option is of bool type and defaults to false.
If the value is true, the reponse data of s3 GetUsage like below:
"stats": {
"TotalBytes": 516,
"TotalBytesRounded": 1024,
"TotalEntries": 1
}
Or if the value is false, the reponse of s3 GetUsage like below and as it does before we add this config option:
{
516,
1024,
1
}.
11.0.0
------
* If you have manually specified the monitor user rocksdb via the
``mon keyvaluedb = rocksdb`` option, you will need to manually add a file
to the mon data directory to preserve this option::
echo rocksdb > /var/lib/ceph/mon/ceph-`hostname`/kv_backend
New monitors will now use rocksdb by default, but if that file is
not present, existing monitors will use leveldb. The ``mon keyvaluedb`` option
now only affects the backend chosen when a monitor is created.
* The 'osd crush initial weight' option allows you to specify a CRUSH
weight for a newly added OSD. Previously a value of 0 (the default)
meant that we should use the size of the OSD's store to weight the
new OSD. Now, a value of 0 means it should have a weight of 0, and
a negative value (the new default) means we should automatically
weight the OSD based on its size. If your configuration file
explicitly specifies a value of 0 for this option you will need to
change it to a negative value (e.g., -1) to preserve the current
behavior.
* The `osd crush location` config option is no longer supported. Please
update your ceph.conf to use the `crush location` option instead.
* The static libraries are not included by the debian development packages
(lib*-dev) any more. As it is not required per debian packaging policy.
And their shared versions are packaged as before.
* The libtool pseudo-libraries (.la files) are not included by the debian
development packages (lib*-dev) any more. As it is unneeded, and per
https://wiki.debian.org/ReleaseGoals/LAFileRemoval and
https://www.debian.org/doc/manuals/maint-guide/advanced.en.html,
we should remove them.
* The jerasure and shec plugins can now detect SIMD instruction at runtime
and no longer need to be built for different processors. The following
plugins are now deprecated: jerasure_generic, jerasure_sse3, jerasure_sse4,
jerasure_neon, shec_generic, shec_sse3, shec_sse4, and shec_neon. If you use any
of these plugins directly you will see a warning in the mon log file.
Please switch to using just 'jerasure' or 'shec'.
