Method for logical volume conversions |
摘要 |
A logical volume is converted from a first format on a first physical volume to a second format on a second physical volume while the logical volume remains available to applications and users. The online conversion is made possible by allowing a temporary mirroring of the existing physical volume(s) with the new physical volumes, using different characteristics on the two physical volumes.
