Because the device is in use, this mapping will fail.

After reviewing the output from the getinfo.sh script, I noticed that the partition type on two of my disks (sdc and sdd) is Linux "type 83" when they should be LVM "type 8e". I don't know how they would have been changed or if this could cause my issue, but I will investigate to see if I can change these safely with fdisk.System and Disk Info:Code: Select all== BEGIN uname -rmi ==
