.SH EXAMPLES
Convert a linear LV to a two-way mirror LV:
.br
.B lvconvert \-\-type mirror \-\-mirrors 1 vg/lvol1
Convert a linear LV to a two-way RAID1 LV:
.br
.B lvconvert \-\-type raid1 \-\-mirrors 1 vg/lvol1
Convert a mirror LV to use an in\-memory log:
.br
.B lvconvert \-\-mirrorlog core vg/lvol1
Convert a mirror LV to use a disk log:
.br
.B lvconvert \-\-mirrorlog disk vg/lvol1
Convert a mirror or raid1 LV to a linear LV:
.br
.B lvconvert --type linear vg/lvol1
Convert a mirror LV to a raid1 LV with the same number of images:
.br
.B lvconvert \-\-type raid1 vg/lvol1
Convert a linear LV to a two-way mirror LV, allocating new extents from specific
PV ranges:
.br
.B lvconvert \-\-mirrors 1 vg/lvol1 /dev/sda:0\-15 /dev/sdb:0\-15
Convert a mirror LV to a linear LV, freeing physical extents from a specific PV:
.br
.B lvconvert \-\-type linear vg/lvol1 /dev/sda
Split one image from a mirror or raid1 LV, making it a new LV:
.br
.B lvconvert \-\-splitmirrors 1 \-\-name lv_split vg/lvol1
Split one image from a raid1 LV, and track changes made to the raid1 LV
while the split image remains detached:
.br
.B lvconvert \-\-splitmirrors 1 \-\-trackchanges vg/lvol1
Merge an image (that was previously created with \-\-splitmirrors and
\-\-trackchanges) back into the original raid1 LV:
.br
.B lvconvert \-\-mergemirrors vg/lvol1_rimage_1
Replace PV /dev/sdb1 with PV /dev/sdf1 in a raid1/4/5/6/10 LV:
.br
.B lvconvert \-\-replace /dev/sdb1 vg/lvol1 /dev/sdf1
Replace 3 PVs /dev/sd[b-d]1 with PVs /dev/sd[f-h]1 in a raid1 LV:
.br
.B lvconvert \-\-replace /dev/sdb1 \-\-replace /dev/sdc1 \-\-replace /dev/sdd1
.RS
.B vg/lvol1 /dev/sd[fgh]1
.RE

.br
.B lvconvert \-\-replace /dev/sdb1 \-\-replace /dev/sdc1 vg/lvol1 /dev/sd[gh]1
Convert an LV into a thin LV in the specified thin pool. The existing LV
is used as an external read\-only origin for the new thin LV.
.br
.B lvconvert \-\-type thin \-\-thinpool vg/tpool1 vg/lvol1
Convert an LV into a thin LV in the specified thin pool. The existing LV
is used as an external read\-only origin for the new thin LV, and is
renamed "external":
.br
.B lvconvert \-\-type thin \-\-thinpool vg/tpool1
.RS
.B \-\-originname external vg/lvol1
.RE
Convert an LV to a cache pool LV using another specified LV for cache pool
metadata:
.br
.B lvconvert \-\-type cache-pool \-\-poolmetadata vg/poolmeta1 vg/lvol1
Convert an LV to a cache LV using the specified cache pool and chunk size:
.br
.B lvconvert \-\-type cache \-\-cachepool vg/cpool1 \-c 128 vg/lvol1
Detach and keep the cache pool from a cache LV:
.br
.B lvconvert \-\-splitcache vg/lvol1
Detach and remove the cache pool from a cache LV:
.br
.B lvconvert \-\-uncache vg/lvol1
