I'm setting up LVM over MD (raid1) for the first time .. we've previously used hardware RAID ... and running into a problem with setup-storage that I don't understand. It should be building a pair of RAIDs using /dev/sda and /dev/sdb, but it's also pulling in /dev/sdc and /dev/sdd for some reason. My config is very similar to the example in the man page, with only the LVM layout different.
Can anyone see what I'm getting wrong? I think I've been over all the relevant parts of the man page, but I'm not spotting my error. This is my disk_config file: disk_config disk1 disklabel:gpt-bios bootable:1 fstabkey:uuid primary - 350 - - primary swap 16G - - primary - 0- - - disk_config disk2 sameas:disk1 disk_config raid fstabkey:uuid raid1 /boot disk1.1,disk2.1 ext4 rw,noatime,errors=rmount-ro raid1 - disk1.3,disk2.3 - - disk_config lvm fstabkey:uuid vg vg_system md1 vg_system-root / 25G ext4 rw,noatime,errors=remount-ro vg_system-home /home 100G- ext4 rw,noatime,nosuid,nodev createopts="-L home -m 1" tuneopts="-c 0 -i 0" vg_system-usr /usr 100G ext4 rw,noatime And this is my format.log after it runs: Starting setup-storage 3.0 Using config file: /var/lib/fai/config/disk_config/srv03 Parted could not read a disk label (new disk?)
