[9fans] 9front nvram setup

I am setting up a CPU server on 9front, and have been getting the following
errors that I just can't seem to work around.
can't write to nvram: i/o error

I have set my nvram in plan9.ini to

nvram=#S/sdE2/nvram
nvroff=0
nvrlen=0

for reference, not reading the documentation and assuming you can just set things like nvrlen to 0, might be the start of issues. What is the appopriate value for that? I set it to 256 and it worked.

To the kind person who called and made sure I was all set, what was your
name again? Thank you, kind human!

You can break into rc shell at the bootargs prompt by typing !rc

then you can inspect the state of the sata drive.

cd /dev/sdE2
ls
cat ctl

Check if the nvram partition is here.

I'm curious as it complains only on write?

It was that nvrlen setting. Apparently that needs to be something like 256
or it gets mad. It didnt like 0.

Sent from my phone. Please excuse the fact that I can't type on these
things to save my life.

all right! good catch :D

iirc these are optional, i usually just set nvram= and nothing else.
nvr is fixed size anyway.
