.SH NAME
.PP
flashcache_load \- load an existing writeback cache volume
.SH DESCRIPTION
.PP
Attach a previously created flashcache volume to the system.
The loaded volume will appear as as \f[I]/dev/mapper/cachedevname\f[].
.PP
This command is useful in \f[I]writeback\f[] mode only.
For the \f[B]writethrough\f[] and \f[B]writearound* the
\f[]flashcache_load** command is not needed; Instead
\f[B]flashcache_create\f[](8) should be used each time.
See the \f[B]flashcache_create\f[](8) for a description of supported
cache mods.
.SH SYNOPSIS
.PP
flashcache_load \f[I]cache_devname\f[] \f[I][cachedev_name]\f[]
.SH EXAMPLE
.TP
.B 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\[aq]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.
