Package: fai-setup-storage Version: 5.8.4 Severity: normal Tags: upstream TLDR: setup-storage fails to remove existing RAID device if a LVM volume is active on it. I have a machine with 2 hard drives (vda and vdb) I use the following setup-storage configuration file: disk_config disk1 bootable:1 disklabel:gpt-bios primary - 0- - - disk_config disk2 sameas:disk1 # disk_config raid fstabkey:label raid1 - disk1.1,disk2.1 - - # disk_config lvm fstabkey:label vg vg0 md0 # vg0-root / 0- xfs rw createopts="-f -L SYSTEM" which create a raid device using both drives and create a LVM root partition. and it works well on blank drives: Starting setup-storage 2.2 Using config file: raid+lvm.conf Parted could not read a disk label (new disk?) Executing: parted -s /dev/vda mklabel gpt Parted could not read a disk label (new disk?) Executing: parted -s /dev/vdb mklabel gpt No volume groups found.

Did I miss something? TIA
