Kilo
⑉ 45 volume drivers with CI
⑉ 25 volume drivers removed with no CI
⑉ 75 blueprints done
⑉ 353 bug fixes done
⑉ Release note items include documentation
for new features! Check it out!
http://bit.ly/1ejTj6Y
Liberty So Far...
⑉ 19 new volume drivers all with CI’s!
⑉ 29 blueprints done
⑉ 134 bug fixes done
Nested Quotas
⑉ Hierarchy Quotas
⑉ Have project admins manage quota of
descendant projects.
⑉ Read full spec at http://bit.ly/1LTVR74
Worked on by: Vilobh Meshram
Force Detach
⑉ A solution to “my volume is stuck in the
attaching state”, FINALLY.
⑉ Operators and end users can safely detach
stuck volumes.
⑉ No fussing with the database!
⑉ Read full spec at http://bit.ly/1T4uStG
Worked on by: Scott DAngelo
Generic Image Cache
⑉ Popular images are cached, not copied over
the network like today.
⑉ Volumes created faster from images!
⑉ All volume drivers can take advantage of
this!
⑉ Read full spec at http://bit.ly/1BWJSFD
Worked on by: Patrick East
Rolling Upgrade pt 2
⑉ From Kilo onwards, we allow schema
upgrades to be independent of services.
⑉ Cross project initiative in OSLO.
⑉ In Liberty, we will have RPC compatibility.
⑉ Upgrade your Cinder services in any order
like you just don’t care!
⑉ Read full spec at http://bit.ly/1ei8RZ3
Worked on by: Thang Pham
Capabilities
⑉ Cinder client can tell you what your storage
backend can do!
⑉ Clients like Horizon can use this information
to provide what you can put in an extra spec.
Less error prone!
⑉ Read full spec at http://bit.ly/1LCeRct
Worked on by: Mike Perez
Improving migrations
⑉ Today, operators migrate an available volume from
backend to backend, or same backend pool to pool.
⑉ Sometimes it’ll take a while. Progress status
coming soon!
⑉ Operator can force migrate. Marks a volume in
maintenance state and can’t be used by end user.
⑉ Read full spec at http://bit.ly/1Jw9xYG
Worked on by: Vincent Hou
Etc...
⑉ Improvements with Nova’s use of Cinder’s
API and error handling.
⑉ Python 3 ready.
Thank you!
