This assumes that if the mon does not explicitly specify the kv type that it is leveldb. No prior version of Ceph has had non-experimental rocksdb, so this is relatively safe. It's also necessary because the default is now 'rocksdb' and we shouldn't assume those old mons are rocksdb. This will break for users to explicitly specified rocksdb for the mon despite it being experimental. Signed-off-by: Sage Weil <sage@redhat.com>

|
|
|
* 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
|
|
}.
|
|
|
|
* If your monitors are configured to use the experimental rocksdb
|
|
backend, you may need to manually adjust the store before upgraded.
|
|
Monitors now explicitly record what keyvalue backend type they use. If
|
|
the kv_backend file is missing from the mon_data directory (normally
|
|
/var/lib/ceph/mon/$cluster-$name/kv_backend) it is now assumed to be leveldb.
|
|
If you had manually configured the mon to use rocksdb, this file should
|
|
be created and filled with the string "rocksdb" (newline optional).
|
|
|

|
|
------
|
|
|
|
* 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'.
