- -r, -ratio <r1>[,<r2>] - Specifies that how much percentage of the cache
- space will be dedicated to writing cache.
- <r1> is the ratio value for the level-1 cache,
- and <r2> is the value for the level-2 cache.
- Possible values are numbers from 0 to 100, or
- 255 which means the whole cache space is shared
- by reading and writing.
- The default values are 255 (shared) for level-1
- cache and 0 (read-only) for level-2 cache.
- Example: -r 80,60 means that 80 of L1 cache
- will be used for writing and 20 for reading,
- while 60 of L2 cache will be used for writing
- and 40 for reading.

- -x, -voladv <spec> - By default, all volumes within a cache task
- follow the task's cache settings. This option
- can specify individual settings and turn off
- some unwanted functions for each volume.
- <spec> states a volume and its settings. It
- has the following format, where "v" represents
- the volume index and each "x" represents a
- setting value which is a decimal number.
- v-xxxx
- The settings represented by "x", from left to
- right, are Strategy, L2 Cache, Defer-Write and
- Prefetch. The following table lists their
- possible values.
- Strategy:
- 0 Default
- 2 Read-Only
- 3 Write-Only
- L2 Cache/Defer-Write/Prefetch:
- 0 Default
- 2 Disabled
- (Default - Follows the cache task setting)
- For example, "-x 4-3220" specifies individual
- settings for the volume #4 as below: Write-Only
- strategy, L2 Cache disabled, Defer-Write
- disabled, while Prefetch is not specified,
- using the cache task setting.
- Trailing zeros in the "xxxx" format can be
- ignored. So above example equals to "-x 4-322".
- Two or more <spec> are separated by ",". For
- example, "-x 4-3220,1-0222" sets the settings
- for the volume #4 and #1.
