I’ve defined a disk like that and do not want it to be wiped/the partition table to be recreated – I just want to use and mount it:
variant: fcos version: 1.3.0 storage: disks: - device: /dev/disk/by-id/usb-[…]:0 wipe_table: false partitions: - size_mib: 0 start_mib: 0 label: external
As I had to discover it seems to be somewhat of an oldish disk, which is still MBR-partitioned (Gparted shows this as
When the Ignition file runs, however, the log tells me one error:
“/dev/disk/by-id/usb-[…]:0” is not a gpt disk
Okay so? In the current Butane spec I also did not find any way to specify that it is a MBR disk, so… uhm… can CoreOS support such a legacy stuff?
Otherwise, the only other way forward for me would be to try the potentially destructive idea of converting the disk from MBR to GPT…
