-module: lvol_cache
-short_description: Configure Cache LVM logical volumes
-description:
-  - This module creates, removes or resizes, converts cache logical volumes.
-options:
-  vg:
-    description:
-    - The volume group this logical volume is part of.
-    required: true
-  lv:
-    description:
-    - The name of the logical volume.
-    required: true
-  size:
-    description:
-    - The size of the logical volume, by
-      default in megabytes or optionally with one of [bBsSkKmMgGtTpPeE] units; or
-      as a percentage of [VG|PVS|FREE]; +size is not implemented, as it is by
-      design not indempodent
-      Float values must begin with a digit.
-  state:
-    choices: [ "present", "absent" ]
-    default: present
-    description:
-    - Control if the logical volume exists. If C(present) the C(size) option
-      is required.
-    required: false
-  force:
-    choices: [ "yes", "no" ]
-    default: "no"
-    description:
-    - Shrink/extend/remove/conversion operations of volumes requires this switch. Ensures that
-      that filesystems get never corrupted/destroyed by mistake.
-    required: false
-  opts:
-    description:
-    - Free-form options to be passed to the lvcreate command
-  pvs:
-    description:
-    - Comma separated list of physical volumes /dev/sda,/dev/sdc
-  type:
-    choices: ["cache", "cache-pool", "normal"]
-    default: normal
-    description:
-    - Type of logical volume, cache is cached lvol, cache-pool is cache pool
-      supplying cached lvol, normal is lvol without any type. To create cache
-      lvol, cache pool must already exist
-  mode:
-    choices: ["writeback", "writethrough"]
-    default: writethrough
-    - This value is used when type is cache pool, specifies how data
-      are written to the lvol
-  pool:
-    description:
-    - This value is used when type is cache, specifies which cache pool will
-      be caching data for cache lvol. Must be in format vg/lv. Cache pool lvol
-      and cache lvol must be from same vg (this is restriction of lvm2).
-notes:
-  - Filesystems on top of the volume are not resized.
