interface, ceph-fuse needs be mounted as root on at least some systems. See
|

issues #9997, #10277, and #10542 for details.

-----
|

|

* The experiemental 'keyvaluestore-dev' OSD backend has been renamed
|
||||
'keyvaluestore' (for simplicity) and marked as experimental. To
|
||||
enable this untested feature and acknowledge that you understand
|
||||
that it is untested and may destroy data, you need to add the
|
||||
following to your ceph.conf::
|
||||
|
||||
enable experimental unrecoverable data corrupting featuers = keyvaluestore
|
||||
|
||||
* The following librados C API function calls take a 'flags' argument whose value
|
||||
is now correctly interpreted:
|
||||
|
||||
rados_write_op_operate()
|
||||
rados_aio_write_op_operate()
|
||||
rados_read_op_operate()
|
||||
rados_aio_read_op_operate()
|
||||
|
||||
The flags were not correctly being translated from the librados constants to the
|
||||
internal values. Now they are. Any code that is passing flags to these methods
|
||||
should be audited to ensure that they are using the correct LIBRADOS_OP_FLAG_*
|
||||
constants.

Release Notes
|
||||
===============
|
||||
|
||||
v0.92
|
||||
=====
|
||||
|
||||
This is the second-to-last chunk of new stuff before Hammer. Big items
|
||||
include additional checksums on OSD objects, proxied reads in the
|
||||
cache tier, image locking in RBD, optimized OSD Transaction and
|
||||
replication messages, and a big pile of RGW and MDS bug fixes.
|
||||
|
||||
Upgrading
|
||||
---------
|
||||
|
||||
* The experimental 'keyvaluestore-dev' OSD backend has been renamed
|
||||
'keyvaluestore' (for simplicity) and marked as experimental. To
|
||||
enable this untested feature and acknowledge that you understand
|
||||
that it is untested and may destroy data, you need to add the
|
||||
following to your ceph.conf::
|
||||
|
||||
enable experimental unrecoverable data corrupting featuers = keyvaluestore
|
||||
|
||||
* The following librados C API function calls take a 'flags' argument whose value
|
||||
is now correctly interpreted:
|
||||
|
||||
rados_write_op_operate()
|
||||
rados_aio_write_op_operate()
|
||||
rados_read_op_operate()
|
||||
rados_aio_read_op_operate()
|
||||
|
||||
The flags were not correctly being translated from the librados constants to the
|
||||
internal values. Now they are. Any code that is passing flags to these methods
|
||||
should be audited to ensure that they are using the correct LIBRADOS_OP_FLAG_*
|
||||
constants.
|
||||
|
||||
* The 'rados' CLI 'copy' and 'cppool' commands now use the copy-from operation,
|
||||
which means the latest CLI cannot run these commands against pre-firefly OSDs.
|
||||
|
||||
* The librados watch/notify API now includes a watch_flush() operation to flush
|
||||
the async queue of notify operations. This should be called by any watch/notify
|
||||
user prior to rados_shutdown().
|
||||
