|
|
|
|
* The *_kb perf counters on the monitor have been removed. These are
|
|
replaced with a new set of *_bytes counters (e.g., cluster_osd_kb is
|
|
replaced by cluster_osd_bytes).
|
|
|
|
* The rd_kb and wr_kb fields in the JSON dumps for pool stats (accessed via
|
|
the 'ceph df detail -f json-pretty' and related commands) have been replaced
|
|
with corresponding *_bytes fields. Similarly, the 'total_space', 'total_used',
|
|
and 'total_avail' fields are replaced with 'total_bytes', 'total_used_bytes',
|
|
and 'total_avail_bytes' fields.
|
|
|
|
* The 'rados df --format=json' output 'read_bytes' and 'write_bytes'
|
|
fields were incorrectly reporting ops; this is now fixed.
|
|
|
|
* The 'rados df --format=json' output previously included 'read_kb' and
|
|
'write_kb' fields; these have been removed. Please use 'read_bytes' and
|
|
'write_bytes' instead (and divide by 1024 if appropriate).

|
|
|
* The client-side caching for librbd is now enabled by default (rbd
|
|
cache = true). A safety option (rbd cache writethrough until flush
|
|
= true) is also enabled so that writeback caching is not used until
|
|
the library observes a 'flush' command, indicating that the librbd
|
|
users is passing that operation through from the guest VM. This
|
|
avoids potential data loss when used with older versions of qemu
|
|
that do not support flush.
