* '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. |
