Wow what a confusing error message, I'm sorry about this!
This seems to be caused by the fact that both disks in the curtin config
have the same wwn:
- {ptable: gpt, serial: Corsair_Force_GS_13207907000097410026, wwn:
'0x0000000000000000',
path: /dev/sda, preserve: true, name: '', grub_device: true, type: disk,
id: disk-sda}
- {ptable: gpt, serial: Corsair_Force_GS_1320790700009741003D, wwn:
'0x0000000000000000',
path: /dev/sdb, preserve: true, name: '', grub_device: true, type: disk,
id: disk-sdb}
This seems to come straight from the udev database:
P: /devices/pci0000:00/0000:00:1f.2/ata1/host0/target0:0:0/0:0:0:0/block/sda
...
E: ID_WWN=0x0000000000000000
E: ID_WWN_WITH_EXTENSION=0x0000000000000000
(and same for sdb). This in turn seems to be because
SCSI_IDENT_LUN_NAA_LOCAL is 0000000000000000 (from 55-scsi-sg3_id.rules)
for both drives and I'm fairly sure that's something sg_inq --export
spits out but now we're really running into the limits of my knowledge
I'm afraid. There's a bug somewhere, maybe in your drives firmware or
maybe in sg3-utils...
