Hi Thoralf, which FAI version are you using? Do you do PXE installation or boot from USB stick? Which ISO are you using? There was a bug when mixing old FAI configs with a new FAI version that no disks are detected if the block device does not belong to the group disk. On my machine this looks like that:
$ ls -l /dev/nvme0n1 brw-rw---- 1 root disk 259, 0 Oct 20 19:50 /dev/nvme0n1 How does it look in your FAI environment? -- best regards Thomas
