Bug#864145: mdadm will only start root device degraded

[Felix Koop]

Package: mdadm
Version: 3.4-4+b1
Severity: important

Dear Maintainer,

I have /dev/md2 as root device. This is a raid1 device constisting of 2
partitions (sdg1 and sdf1). When I decided to encrypt those partitions,
I started to encrypt one of them (sdg1). Now the array always starts
degraded with the encrypted sdg1 missing. I can after every boot run

mdadm /dev/md2 --add /dev/mapper/cryptorootg

and the device is working again until next reboot. An entry in
/etc/crypttab is created and the device is apparently unlocked as I
don't need to enter the password after the boot process.

What do I have to configure differently to have mdadm recognising the
second device during boot?

Hi Felix,

Do you still use this setup, and do you still have the issue?

What is in your /etc/crypttab? Do you perhaps need an offset to
preserve mdadm metadata? For example, I have 'offset=8' for an
encrypted swap partition, but it is not an mdadm device:

cryptswap /dev/mapper/optivg-swap /dev/urandom
swap,offset=8,cipher=aes-cbc-essiv:sha256,size=256,hash=ripemd160

The last suggestion is just a guess.

Kind regards
Felix Lechner

Hi,

this setup works (both when installing new with d-i and when later
migrating it manually to it). since there's a long time no answer here
and the system most likely has been resetup, I'm closing this bug.

Regards,
Daniel
