Detailed Description

Cache attach configuration.

Field Documentation

force

bool force

Ignore warnings and initialize new cache instance.

If set to true, it will force initializing new cache despite the existing metadata from previous cache instance.

Note

This flag is not allowed when loading existing cache instance.

open_cores

bool open_cores

Automatically open core volumes when loading cache.

If set to false, cache load will not attempt to open core volumes, and so cores will be marked "inactive" unless their volumes were earlier added to the core pool. In such case user will be expected to add cores later using function ocf_mngt_cache_add_core().

Note

This option is meaningful only with ocf_mngt_cache_load(). When used with ocf_mngt_cache_attach() it's ignored.
