# lvconvert

> Convert or modify the type, redundancy, or state of logical volumes.
> More information: <https://manned.org/lvconvert>.

- Convert a linear logical volume to RAID1 (add one mirror: two copies total):

`lvconvert --type raid1 {{[-m|--mirrors]}} 1 {{/dev/vg_name/lv_name}}`

- Remove mirroring and convert back to a linear logical volume:

`lvconvert {{[-m|--mirrors]}} 0 {{/dev/vg_name/lv_name}}`

- Merge a snapshot back into its origin logical volume (applies on next activation):

`lvconvert --merge {{/dev/vg_name/snapshot_lv}}`

- Repair a degraded RAID logical volume:

`lvconvert --repair {{/dev/vg_name/lv_name}}`

- Convert an existing logical volume into a thin pool with a separate metadata LV:

`lvconvert --type thin-pool --poolmetadata {{/dev/vg_name/pool_metadata_lv}} {{/dev/vg_name/pool_lv}}`
