Tuesday January 14th, 2024 NCLUG Meeting

[Evelyn Mitchell]

Thanks for the recap Bob!

To clarify, my issue was related to ZFS + LUKS. I didn't save, or wasn't
offered the opportunity to save the ZFS recovery password in plain text,
when I set up my laptop, years ago. Then when I needed to do a recovery, I
was quickly in the weeds.

So, if you are running ZFS+LUKS, check to see if you have the ZFS rpool key
file in plain text.

Note, this is a very unusual setup, so I doubt there are more than a
handful of people running with both ZFS encryption and LUKS encryption.

I used my LUKS password daily, so I never forgot it, but had no idea there
was even a separate ZFS encryption key, let alone that I didn't have a
plaintext recovery file, until it was too late.

Entirely self inflicted, by being on the cutting edge of tech in open
source.

I hope this helps,
Evelyn
