show unwritable-cache
Description Shows the percentage of unwritable data in the system. This data cannot be written to disk because it is
associated with a volume that no longer exists or whose disks are not online. If the data is needed,
the volume’s disks must be brought online. If the data is not needed it can be cleared, in which case
it will be lost and data will differ between the host and disk.
