Fine, thank you. Why is it not detected as EFI like SDA1 ?
That's just the way parted describes things.
Model: Generic Flash Disk (scsi)
Disk /dev/sda: 124GB
Sector size (logical/physical): 2048B/512B
Partition Table: mac
Disk Flags:
Number Start End Size File system Name Flags
1 2048B 6143B 4096B Apple
2 1925kB 2351kB 426kB EFI
I'm slightly worried by that "Apple" partition on sda - is this a Mac?
No !! I think it is mistake of parted. It is a flash usb key, filled by dd
if=debian-9.1.0-amd64-netinst.iso
Really? (checks) Wow, OK - parted is on serious crack there. fdisk is
more sane, and on the same image will show:
# fdisk -l /dev/sdc

What does fdisk show on sdb for you?
Normal results :
root@nous:/# fdisk -l /dev/sdb
Disk /dev/sdb: 1.8 TiB, 2000398934016 bytes, 3907029168 sectors

/dev/sdb2 1953792 3907028991 3905075200 1.8T 83 Linux
and.... on sda the same results you get on your sdc !!
What do you think an "EFP" is?? ESP is the normal name.
yes sorry (I am a bit lost).
OK.
Now, I think I need to install grub on sdb1, but it refuses :
root@nous:/# grub-install /dev/sdb1
Installing for i386-pc platform.
grub-install: warning: File system `fat' doesn't support embedding.
grub-install: error: filesystem `btrfs' doesn't support blocklists.
Right. Either you're not booted in EFI mode, or /sys is not
mounted. Grub is assuming you're on a normal BIOS-boot machine. Make
sure that you have /sys mounted, and /dev/sdb1 mounted on /boot/efi,
then run
# grub-install --target x86_64-efi
and see what it does.
root@nous:/# mount /dev/sdb1 /boot/efi
root@nous:/# mount /dev/sdb1 /boot/efi
mount: /dev/sdb1 is already mounted or /boot/efi busy
/dev/sdb1 is already mounted on /boot/efi
root@nous:/# grub-install --target x86_64-efi
grub-install: error: /usr/lib/grub/x86_64-efi/modinfo.sh doesn't exist.
Please specify --target or --directory.
root@nous:/# ls /usr/lib/grub
grub-mkconfig_lib i386-pc
I thank you very much of your help - and I am honoured - but I could
follow some hoto if find one, but I do not find one.
It is surprising, I suppose am not the first to try make a btrfs raid1...
