List Pools
==========
-To list your cluster's pools, run the following command:
+There are multiple ways to get the list of pools in your cluster.
+
+To list just your cluster's pool names (good for scripting), execute:
+
+.. prompt:: bash $
+
+ ceph osd pool ls
+
+::
+
+ .rgw.root
+ default.rgw.log
+ default.rgw.control
+ default.rgw.meta
+
+To list your cluster's pools with the pool number, run the following command:
.. prompt:: bash $
ceph osd lspools
+::
+
+ 1 .rgw.root
+ 2 default.rgw.log
+ 3 default.rgw.control
+ 4 default.rgw.meta
+
+To list your cluster's pools with additional information, execute:
+
+.. prompt:: bash $
+
+ ceph osd pool ls detail
+
+::
+
+ pool 1 '.rgw.root' replicated size 3 min_size 1 crush_rule 0 object_hash rjenkins pg_num 1 pgp_num 1 autoscale_mode on last_change 19 flags hashpspool stripe_width 0 application rgw read_balance_score 4.00
+ pool 2 'default.rgw.log' replicated size 3 min_size 1 crush_rule 0 object_hash rjenkins pg_num 1 pgp_num 1 autoscale_mode on last_change 21 flags hashpspool stripe_width 0 application rgw read_balance_score 4.00
+ pool 3 'default.rgw.control' replicated size 3 min_size 1 crush_rule 0 object_hash rjenkins pg_num 1 pgp_num 1 autoscale_mode on last_change 23 flags hashpspool stripe_width 0 application rgw read_balance_score 4.00
+ pool 4 'default.rgw.meta' replicated size 3 min_size 1 crush_rule 0 object_hash rjenkins pg_num 1 pgp_num 1 autoscale_mode on last_change 25 flags hashpspool stripe_width 0 pg_autoscale_bias 4 application rgw read_balance_score 4.00
+
+To get even more information, you can execute this command with the ``--format`` (or ``-f``) option and the ``json``, ``json-pretty``, ``xml`` or ``xml-pretty`` value.

Creating a Pool
:Type: Integer
:Valid Range: ``1`` sets flag, ``0`` unsets flag
-.. _hit_set_type:
-
-.. describe:: hit_set_type
-
- :Description: Enables HitSet tracking for cache pools.
- For additional information, see `Bloom Filter`_.
- :Type: String
- :Valid Settings: ``bloom``, ``explicit_hash``, ``explicit_object``
- :Default: ``bloom``. Other values are for testing.
-
-.. _hit_set_count:
-
-.. describe:: hit_set_count
-
- :Description: Determines the number of HitSets to store for cache pools. The
- higher the value, the more RAM is consumed by the ``ceph-osd``
- daemon.
- :Type: Integer
- :Valid Range: ``1``. Agent doesn't handle > ``1`` yet.
-
-.. _hit_set_period:
-
-.. describe:: hit_set_period
-
- :Description: Determines the duration of a HitSet period (in seconds) for
- cache pools. The higher the value, the more RAM is consumed
- by the ``ceph-osd`` daemon.
- :Type: Integer
- :Example: ``3600`` (3600 seconds: one hour)
-
-.. _hit_set_fpp:
-
-.. describe:: hit_set_fpp
-
- :Description: Determines the probability of false positives for the
- ``bloom`` HitSet type. For additional information, see `Bloom
- Filter`_.
- :Type: Double
- :Valid Range: ``0.0`` - ``1.0``
- :Default: ``0.05``
-
-.. _cache_target_dirty_ratio:
-
-.. describe:: cache_target_dirty_ratio
-
- :Description: Sets a flush threshold for the percentage of the cache pool
- containing modified (dirty) objects. When this threshold is
- reached, the cache-tiering agent will flush these objects to
- the backing storage pool.
- :Type: Double
- :Default: ``.4``
-
-.. _cache_target_dirty_high_ratio:
-
-.. describe:: cache_target_dirty_high_ratio
-
- :Description: Sets a flush threshold for the percentage of the cache pool
- containing modified (dirty) objects. When this threshold is
- reached, the cache-tiering agent will flush these objects to
- the backing storage pool with a higher speed (as compared with
- ``cache_target_dirty_ratio``).
- :Type: Double
- :Default: ``.6``
-
-.. _cache_target_full_ratio:
-
-.. describe:: cache_target_full_ratio
-
- :Description: Sets an eviction threshold for the percentage of the cache
- pool containing unmodified (clean) objects. When this
- threshold is reached, the cache-tiering agent will evict
- these objects from the cache pool.
-
- :Type: Double
- :Default: ``.8``
-
.. _target_max_bytes:
.. describe:: target_max_bytes
:Type: Integer
:Example: ``1000000`` #1M objects

-.. describe:: hit_set_grade_decay_rate
-
- :Description: Sets the temperature decay rate between two successive
- HitSets.
- :Type: Integer
- :Valid Range: 0 - 100
- :Default: ``20``
-
-.. describe:: hit_set_search_last_n
-
- :Description: Count at most N appearances in HitSets. Used for temperature
- calculation.

- :Default: ``1``
-
-.. _cache_min_flush_age:
-
-.. describe:: cache_min_flush_age
-
- :Description: Sets the time (in seconds) before the cache-tiering agent
- flushes an object from the cache pool to the storage pool.
- :Type: Integer
- :Example: ``600`` (600 seconds: ten minutes)
-
-.. _cache_min_evict_age:
-
-.. describe:: cache_min_evict_age
-
- :Description: Sets the time (in seconds) before the cache-tiering agent
- evicts an object from the cache pool.
- :Type: Integer
- :Example: ``1800`` (1800 seconds: thirty minutes)
