NAME
       cache_metadata_size  -  Estimate the size of the metadata device needed
       for a given configuration.

SYNOPSIS
       cache_metadata_size [options]

DESCRIPTION
       cache_metadata_size estimates the size of the metadata.
	      Either --nr-blocks, or --block-size and  --device-size  must  be
	      specified.

OPTIONS
       --nr-blocks {natural}
	      Specify the number of cache blocks.

       --block-size {sectors}
	      Specify the size of each cache block in 512 byte sectors.

       --device-size {sectors}
	      Specify total size of the fast device used in the cache.	In 512
	      byte sectors.

       --max-hint-width {nr bytes}
	      Specify hint width.

	   Cache policies use a per block 'hint' to record extra info (for instance
	   hit counts).	 At the moment all policies use a 4 byte hint
	   width.  If you want to use a different hint width specify it with this
	   switch.

EXAMPLE
       $ cache_metadata_size --nr-blocks 10240

       $ cache_metadata_size --block-size 128 --device-size 1024000
