Changeset 3432 in MondoRescue

Timestamp:

Aug 28, 2015, 2:34:47 AM (10 years ago)

Author:

Message:

• Change analyze-my-lvm in order to generate percentage of Extents of a VG to use to create the LV instead of a fixed size. Should improve bugs when creating LVM on a disk of different size greatly.
