Description Rich Megginson 2023-07-19 18:36:02 UTC

raid volumes do not remove existing data from member disks as needed before creation
It should use self._blivet.devicetree.recursive_remove like BlivetPool._create_members does
By calling recursive_remove() on each device before creating the RAID volume, you can ensure that any existing data on the member disks is removed.
