Thomas, Ok, this is helpful. I found this blog : https://terrydactyl10.wordpress.com/2015/11/04/centos-7-with-mdadm-software-raid-and-uefi-boot/
So here is my resulting disk_config file now : # example of new config file for setup-storage # # <type> <mountpoint> <size> <fs type> <mount options> <misc options> disk_config disk1 disklabel:gpt fstabkey:uuid bootable:1 primary - 500 - - primary /boot/efi 1G vfat rw createopts="-F32" primary swap 2G swap sw,pri=1 primary - 0- - - #disk_config disk2 sameas:disk1 disk_config disk2 disklabel:gpt fstabkey:uuid primary - 500 - - primary /boot/efi2 1G vfat rw createopts="-F32" primary swap 2G swap sw,pri=1 primary - 0- - - disk_config raid disklabel:gpt fstabkey:uuid raid1 /boot disk1.1,disk2.1 ext4 rw,noatime,errors=remount-ro raid1 - disk1.4,disk2.4 - - disk_config lvm fstabkey:uuid vg vg_system md1 vg_system-root / 40G-200G ext4 rw,noatime vg_system-tmp /tmp 20G-50G ext4 rw,noatime,nosuid,nodev vg_system-scratch /scratch 30%- ext2 rw,noatime ##vg_system-home /home 30%- ext4 rw,noatime,nosuid,nodev Maybe I can try it now.
