Landscape Ceph Cache Fix

Learn about configurations >

• auth-supported | string

  Default: cephx

  Which authentication flavour to use. . Valid options are "cephx" and "none". If "none" is specified, keys will still be created and deployed so that it can be enabled later.

• ephemeral-unmount | string

  Cloud instances provider ephermeral storage which is normally mounted on /mnt. . Providing this option will force an unmount of the ephemeral device so that it can be used as a OSD storage device. This is useful for testing purposes (cloud deployment is not a typical use case).

• fsid | string

  fsid of the ceph cluster. To generate a suitable value use `uuid` . This configuration element is mandatory and the service will fail on install if it is not provided.

• key | string

  Key ID to import to the apt keyring to support use with arbitary source configuration from outside of Launchpad archives or PPA's.

• monitor-count | int

  Default: 3

  How many nodes to wait for before trying to create the monitor cluster this number needs to be odd, and more than three is a waste except for very large clusters.

• monitor-secret | string

  This value will become the mon. key. To generate a suitable value use: . ceph-authtool /dev/stdout --name=mon. --gen-key . This configuration element is mandatory and the service will fail on install if it is not provided.

• osd-devices | string

  Default: /dev/vdb

  The devices to format and set up as osd volumes. . These devices are the range of devices that will be checked for and used across all service units. . For ceph >= 0.56.6 these can also be directories instead of devices - the charm assumes anything not starting with /dev is a directory instead.

• osd-format | string

  Default: xfs

  Format of filesystem to use for OSD devices; supported formats include: . xfs (Default >= 0.48.3) ext4 (Only option < 0.48.3) btrfs (experimental and not recommended) . Only supported with ceph >= 0.48.3.

• osd-journal | string

  The device to use as a shared journal drive for all OSD's. By default no journal device will be used. . Only supported with ceph >= 0.48.3.

• osd-journal-size | int

  Default: 1024

  Ceph osd journal size. The journal size should be at least twice the product of the expected drive speed multiplied by filestore max sync interval. However, the most common practice is to partition the journal drive (often an SSD), and mount it such that Ceph uses the entire partition for the journal. . Only supported with ceph >= 0.48.3.

• osd-reformat | string

  By default, the charm will not re-format a device that already looks as if it might be an OSD device. This is a safeguard to try to prevent data loss. . Specifying this option (any value) forces a reformat of any OSD devices found which are not already mounted.

• source | string

  Default: cloud:precise-updates/folsom

  Optional configuration to support use of additional sources such as: . - ppa:myteam/ppa - cloud:precise-proposed/folsom - http://my.archive.com/ubuntu main . The last option should be used in conjunction with the key configuration option. . Note that a minimum ceph version of 0.48.2 is required for use with this charm which is NOT provided by the packages in the main Ubuntu archive for precise but is provided in the Folsom cloud archive.

• use-syslog | boolean

  If set to True, supporting services will log to syslog.
