[SOLVED] Not a valid LUKS device

zeta0307 · 2023-04-01 17:54:23

I had a 256G SSD (/dev/sda) and a 1T HDD (/dev/sdb) on my laptop, and created a LVM on LUKS2 configuration is as follows (this is from my installation log):

$ sudo lsblk

Everything works well until I was trying to replace my 256G SSD (/dev/sda) with a new 1T SSD and do a fresh install on the new SSD.
After I replaced the old SSD with the new one and pluged in a usb installation stick I found the usb stick wasn't working, I couldn't boot from the system on the usb stick.
So I changed back to the old SSD, but then I found I could't boot from the system on the old SSD (boot entry disappered on grub menu).
Later I got a working usb arch installation stick and repaired the bootloader on /dev/sda1, successfully booted from the system on the old SSD, but only to found that I couldn't open /dev/sdb1 (lvm on luks too) any more (/dev/sdb2 is not on lvm on luks and works well).

I'm wondering if the partition header is corrupted. If it's not, how can I fix it? Can anyone help me?

commands output:

$ sudo cryptsetup open /dev/sdb1 cryptdata
Device /dev/sdb1 is not a valid LUKS device.

That looks like a LUKS2 header but the primary header JSON metadata is missing

instead there is crap that should not be there (b.o.o.t c.r.y.p.t)

is the secondary header still around? starts at offset 0x4000, not covered by your hexdump

Finally there is key material (only one copy) which is ~250KB of random data per keyslot starting at offset 0x8000 (more specifically, offset and size as stated in the JSON header - which can differ from default after luksChangeKey etc.)

... ~250KB of random data follows ...

You need an intact header (primary or secondary) as well as intact key material.

There is 'cryptsetup repair' and here an example how to use it: https://unix.stackexchange.com/question … 071#706071

But your case looks more severe so it might not help.

I tried the method you linked, unfortunately it didn't work, 'cryptsetup repair' says isn't a valid LUKS device. There is JSON metadata at the secondary header, but magic byte signatures are missing. Key material seems also be there.
I've upload first 16M data of /dev/sdb1 to: https://filetransfer.io/data-package/ub8cVHmI#link.

$ sudo hexdump -s 0x0000 -n 0x8200 -C /dev/sdb1
