NAME¶
flashcache_load - load an existing writeback cache volume
DESCRIPTION¶
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.
SYNOPSIS¶
flashcache_load
cache_devname [cachedev_name]
EXAMPLE¶
- 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.
