| LVCONVERT(8) | LVCONVERT(8) |
| -m, --mirrors Mirrors | Specifies the degree of the mirror you wish to create. For example, "-m 1" would convert the original logical volume to a mirror volume with 2-sides; that is, a linear volume plus one copy. |
| --mirrorlog {disk|core} | Specifies the type of log to use. The default is disk, which is persistent and requires a small amount of storage space, usually on a separate device from the data being mirrored. Core may be useful for short-lived mirrors: It means the mirror is regenerated by copying the data from the first device again every time the device is activated - perhaps, for example, after every reboot. |
| --corelog | The optional argument "--corelog" is the same as specifying "--mirrorlog core". |
| -R, --regionsize MirrorLogRegionSize | A mirror is divided into regions of this size (in MB), and the mirror log uses this granularity to track which regions are in sync. |
| -b, --background | Run the daemon in the background. |
| -i, --interval Seconds |
Report progress as a percentage at regular intervals. |
| -s, --snapshot | Create a snapshot from existing logical volume using another existing logical volume as its origin. |
| -c, --chunksize ChunkSize | Power of 2 chunk size for the snapshot logical volume between 4k and 512k. |
| -Z, --zero y|n |
Controls zeroing of the first KB of data in the snapshot. If the volume is read-only the snapshot will not be zeroed. |
