|
|
|
* The RGW "num_rados_handles" has been removed.
|
|
* If you were using a value of "num_rados_handles" greater than 1
|
|
multiply your current "objecter_inflight_ops" and
|
|
"objecter_inflight_op_bytes" paramaeters by the old
|
|
"num_rados_handles" to get the same throttle behavior.
|
|
|
|
* Ceph now packages python bindings for python3.6 instead of
|
|
python3.4, because EPEL7 recently switched from python3.4 to
|
|
python3.6 as the native python3. see the `announcement <https://lists.fedoraproject.org/archives/list/epel-announce@lists.fedoraproject.org/message/EGUMKAIMPK2UD5VSHXM53BH2MBDGDWMO/>_`
|
|
for more details on the background of this change.
|
|
|
|
* librbd now uses a write-around cache policy be default,
|
|
replacing the previous write-back cache policy default.
|
|
This cache policy allows librbd to immediately complete
|
|
write IOs while they are still in-flight to the OSDs.
|
|
Subsequent flush requests will ensure all in-flight
|
|
write IOs are completed prior to completing. The
|
|
librbd cache policy can be controlled via a new
|
|
"rbd_cache_policy" configuration option.
|
|
|
|
* librbd now includes a simple IO scheduler which attempts to
|
|
batch together multiple IOs against the same backing RBD
|
|
data block object. The librbd IO scheduler policy can be
|
|
controlled via a new "rbd_io_scheduler" configuration
|
|
option.
