In some cases when OSD metadata disks are reused and redeployed,
lvcreate can fail to create a DB or WAL volume because it overlaps
an old, deleted volume on the same disk whose signature still
exists at the offsets that trigger detection and abort the LV
creation process when the user is asked whether or not to wipe to
old signature. Adding a --yes argument to the lvcreate command
automatically answers yes to the wipe question and allows lvcreate
to wipe the old signature.
