- Convert a linear logical volume to RAID1 (add one mirror: two copies total):
`lvconvert --type raid1 {{[-m|--mirrors]}} 1 {{/dev/vg_name/lv_name}}`
`sudo 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}}`
`sudo 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}}`
`sudo lvconvert --merge {{/dev/vg_name/snapshot_lv}}`
- Repair a degraded RAID logical volume:
`lvconvert --repair {{/dev/vg_name/lv_name}}`
`sudo 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}}`
`sudo lvconvert --type thin-pool --poolmetadata {{/dev/vg_name/pool_metadata_lv}} {{/dev/vg_name/pool_lv}}`
