|
* librados::Rados::pool_create_async() and librados::Rados::pool_delete_async()
|
|
don't drop a reference to the completion object on error, caller needs to take
|
|
care of that. This has never really worked correctly and we were leaking an
|
|
object
|
|
|
|
* 'ceph osd crush set <id> <weight> <loc..>' no longer adds the osd to the
|
|
specified location, as that's a job for 'ceph osd crush add'. It will
|
|
however continue to work just the same as long as the osd already exists
|
|
in the crush map.
|
|
|
|
* The OSD now enforces that class write methods cannot both mutate an
|
|
object and return data. The rbd.assign_bid method, the lone
|
|
offender, has been removed. This breaks compatibility with
|
|
pre-bobtail librbd clients by preventing them from creating new
|
|
images.
|
|
|
|
* librados now returns on commit instead of ack for synchronous calls.
|
|
This is a bit safer in the case where both OSDs and the client crash, and
|
|
is probably how it should have been acting from the beginning. Users are
|
|
unlikely to notice but it could result in lower performance in some
|
|
circumstances. Those who care should switch to using the async interfaces,
|
|
which let you specify safety semantics precisely.
|
|
|
|
* The C++ librados AioComplete::get_version() method was incorrectly
|
|
returning an int (usually 32-bits). To avoid breaking library
|
|
compatibility, a get_version64() method is added that returns the
|
|
full-width value. The old method is deprecated and will be removed
|
|
in a future release. Users of the C++ librados API that make use of
|
|
the get_version() method should modify their code to avoid getting a
|
|
value that is truncated from 64 to to 32 bits.

v0.71
|
|
~~~~~
|
|
|
|
* The MDS now disallows snapshots by default as they are not
|
|
considered stable. The command 'ceph mds set allow_snaps' will
|
|
enable them.
|
|
|
|
* For clusters that were created before v0.44 (pre-argonaut, Spring
|
|
2012) and store radosgw data, the auto-upgrade from TMAP to OMAP
|
|
objects has been disabled. Before upgrading, make sure that any
|
|
buckets created on pre-argonaut releases have been modified (e.g.,
|
|
by PUTing and then DELETEing an object from each bucket). Any
|
|
cluster created with argonaut (v0.48) or a later release or not
|
|
using radosgw never relied on the automatic conversion and is not
|
|
affected by this change.
|
|
|
|
* Any direct users of the 'tmap' portion of the librados API should be
|
|
aware that the automatic tmap -> omap conversion functionality has
|
|
been removed.
|
|
|
|
* Most output that used K or KB (e.g., for kilobyte) now uses a
|
|
lower-case k to match the official SI convention. Any scripts that
|
|
parse output and check for an upper-case K will need to be modified.
