Learn about configurations >

• db-devices | string

  DSL expression to match block devices used as RocksDB carrier devices for config-driven enrollment triggered by osd-devices.

  This option is ignored unless osd-devices is also set.

• db-size | string

  Requested RocksDB partition size for devices selected by db-devices.

  This option is ignored unless osd-devices is also set.

• default-pool-size | int

  Default: 3

  The default replication factor for pools. Note that changing this value only sets the default value; it doesn't change the replication factor for existing pools.

• device-add-flags | string

  Comma-separated list of flags controlling config-driven device addition with the osd-devices flow.

  Supported flags: wipe:osd - Wipe non-pristine OSD devices before enrollment encrypt:osd - Encrypt OSD devices wipe:wal - Wipe WAL carrier devices before use encrypt:wal - Encrypt WAL partitions/devices wipe:db - Wipe DB carrier devices before use encrypt:db - Encrypt DB partitions/devices

  Example: wipe:osd,encrypt:osd,wipe:wal,encrypt:db

  Note: WAL/DB config and these flags only apply to config-driven provisioning initiated by osd-devices. They are not in effect when using the add-osd action, which currently supports only device-level wipe and encryption parameters.

• enable-perf-metrics | boolean

  Include Ceph performance metrics in the prometheus endpoint.

• enable-rgw | string

  Supported values for this option are "*" - Enable RGW on all storage nodes "" - Disable RGW on all storage nodes

• namespace-projects | boolean

  Enable project namespacing. If project namespacing is enabled, keystone projects will be implicitly added to a matching project in radosgw, in addition to updating the catalog URL to allow radosgw to support publicly-readable containers and temporary URLS. This namespacing also allows multiple projects to create buckets with the same names, as the bucket names are namespaced into the project namespaces in the RADOS gateway.

  This configuration option will not be enabled on a charm upgrade, and cannot be toggled on in an existing installation as it will remove tenant access to existing buckets.

• osd-devices | string

  DSL expression to match block devices for config-driven OSD enrollment. The DSL uses functional syntax with predicates and variables.

  Supported predicates: and(), or(), not(), eq(), ne(), gt(), ge(), lt(), le(), in(), re() Supported variables: @type, @vendor, @model, @size, @devnode, @host

  Examples: eq(@type,'nvme') and(eq(@type,'ssd'), ge(@size,100GiB)) or(eq(@type,'ssd'), eq(@type,'nvme'))

  When set, the charm evaluates this expression against available block devices on each unit and enrolls matching devices as OSDs. This is additive to action-based and Juju storage-based OSDs.

• rbd-stats-pools | string

  Enable RBD IO statistics for specified rbd pools.

• region | string

  Default: RegionOne

  Name of the OpenStack region

• site-name | string

  The local site name. This should be unique amongst the connected remote microceph clusters.

• snap-channel | string

  Default: squid/stable

  The snap-channel option determines the MicroCeph snap that is being installed via charm. Change this option to perform an upgrade of MicroCeph. See https://charmhub.io/microceph for details on the upgrade process.

• wait-to-adopt | boolean

  Whether charm microceph should wait for an external ceph cluster to yield admin credentials using which microceph will adopt the external cluster rather than bootstrapping a new ceph cluster on microceph bootstrap.

• wal-devices | string

  DSL expression to match block devices used as WAL carrier devices for config-driven enrollment triggered by osd-devices.

  This option is ignored unless osd-devices is also set.

• wal-size | string

  Requested WAL partition size for devices selected by wal-devices.

  This option is ignored unless osd-devices is also set.
