it might save some other folks a bit of time if you added this to you installation instructions as something to look out for
thanks for all your work and help

rray,

Because you are booting with a really old u-boot, you have this loading problem.

U-Boot 2012.07-rc1 (Jul 27 2012 - 10:07:17)
ZyXEL NSA320 2-Bay Power Media Server

OK

At serial console, change the load initrd address above to 0x02100000. If you're not sure how, get the envs listing, and I'll help modifying it.

printenv

=============

Once you booted into Debian again, consider upgrading u-boot to avoid this problem in the future:

Ah. That should be easy to solve. It explains why the rootfs was not found. Let me look at the log.

i have 2 drives. on both drives partition 1 is boot, 2 is root, 3 is swap, and 4 is data. they are raid 1 and encrypted. md2_crypt is root, md3_crypt is swap, and md4_crypt is data. for some reason dur'n the upgrade from wheezy to stretch the system decided to make the first raid md125 and the second raid md126 but they still get mapped as md2 and md3.
md2_crypt will only be created after i am prompted for a password to decrypt the raid filesystem. i never get a password prompt. i attached a good boot log.

When you said reset everything, what did you do? can you see this device before reboot?

/dev/mapper/md2_crypt

rray,

Do you have serial console? if you do, please post the entire serial boot log.

i set up my nsa320 in 2013 with an encrypted root on the hard drives use'n kernel 3.4.4 and debian wheezy. it has served well for many years. i thought i would bring it up to date so i upgraded to stretch. still use'n the 3.4.4 kernel everything works ok. i thought i would push my luck and upgrade the kernel. i followed the instructions at

for the 5.7.1 kernel. the ramdisk runs ok and it finds all of the disk devices but never prompts for a password to decrypt the devices. it returns
