flashcache_load8

Usage

Overview

Attach a previously created flashcache volume to the system. The loaded volume will appear as as /dev/mapper/cachedevname.

This command is useful in writeback mode only. For the writethrough and writearound* the flashcache_load** command is not needed; Instead flashcache_create(8) should be used each time. See the flashcache_create(8) for a description of supported cache mods.

Examples

flashcache_load cachedev /dev/sdc

Load the existing writeback cache on /dev/sdc, using the virtual cachedev_name from when the device was created. When upgrading from an older flashcache device format that didn't store the cachedev name internally, or the cachedev name shall be changed, the new cachedev name can be supplied as a second argument to flashcache_load.
