Hello Developers¶

I am curious to know if there is something missing from the code for Ceph pool values.

As mentioned in the documentation there are several pool values that we can set and get for any pool.

http://ceph.com/docs/master/rados/operations/pools/#set-pool-values

Here is my observation :

• I am able to set pool values like cache_target_dirty_ratio , target_max_bytes , cache_min_flush_age etc. But unable to get it.
• ceph osd pool get ? -- Does not contain these values in the help. The values that are mentioned in the help are only gettable.

Below is the output from my Ceph setup , if you think this needs to be fixed , you can take necessary actions , else you can close this issue.
