Dear 9fans,
I am booting my Raspberry Pi 4B off the 9legacy SD card image
(http://www.9legacy.org/download.html) and it boots fine with the default
config.txt, but there is a 48-pixel wide black border on the screen.

Yes ping works and I can also make nslookups for hosts that don't match the
wildcard.
$ nslookup server.local

Address: 10.0.0.1
$ nslookup other.local

How did you used disk/prep?
I ran 'disk/prep -bw -a^(9fat nvram fossil swap) /dev/sdE1/plan9'.
When I ran it, my old disk was sdE0 and the new was sdE1. Now I notice
the layout prep created is identical on both disks!
su# disk/prep /dev/sdE0/plan9 # old
9fat0 204800
unicode codepoints (runes) are abstract. we need to deal with encodings.
the encoding utf-8 uses is not a single byte for anything above 0x7f.
so essentially the encoding phase would be name[i] = (uchar)r. the decoding
phase
would be r = (Rune)name[i].
Thank you. I modified trfs.c and
I began consolidating files with great joy from external ext2 disks to
the new 2 TB fossil drive using trfs.latin1. After only 300 or so
gigabytes I saw this on the console:
fossil: diskWriteRaw failed: /dev/sdE0/fossil: score 0x016d1415: data
Sun Oct 16 09:37:58 EDT 2011
part=data block
i've also had trouble with usb disks.
The errors come from sdE0 which is connected to sata port on the
motherboard. Even when there are no usb disks attached at all.

dd -if /dev/sdE0/fossil -of /dev/null -bs 512k # or whatever partition.
No errors, but I noticed it stopped just before 200 gigabytes. The
total size of the plan9 partition is 1.81 terabytes.
A related question: how should I interpret /dev/sdE0/fossil file size?
# ls -l /dev/sdE0/fossil
No errors, but I noticed it stopped just before 200 gigabytes.
I kept reading the disk and got several read errors. Here is the first one:
fossil: diskReadRaw failed: /dev/sdE0/fossil: score 0x016d1389:
part=data block 23925641: eof reading disk
Bad sector or something else?
to me that looks like a mismatch between fossil's expectations for the
partition and that actual partition size. i think you're just reading past
the end of the partition.
Indeed!

I have some files on an external ext2 drive that have whitespace and
umlauts (ä, ö) in them. trfs took care of the whitespace. But ext2srv
presents umlauts as a question mark symbol (�) and won't let me access
the file (error: file does not exist).
Where is the problem? These files show correctly
if you know what the charset on disk is, you could probablly hack ext2fs
into translating names. or (less hacky) you could write a transliterating fs,
or add this to trfs' duties.
Thank you. So now I know ext2srv is not doing any file name conversion. Good.
Say I wanted to add the following
latin-1 bytes 00-FF turn into unicode runes 00-FF.
Then why doesn't it Just Work? Now I am confused (again).
fossil/conf /dev/sdE0/fossil fossil.conf
fossil/conf -w /dev/sdE0/fossil fossil.conf
This was exactly what I needed. Thank you! My migration from old to
new drive is now complete.
you're not the first person to make this mistake, so i should
have remembered this problem. sorry.
Please don't apologize. You are the one guiding the blind.
you need to mount both new and old afresh in /n/ and copy
using your destination as /n/new and source as /n/old. using
/ as your
snarf-paste error. the command was:
su# disk/mkfs -s /n/old -d /n/new -U -r {echo +}
Now let's see if it boots.
Almost there. I took out the old drive and made the new one sdE0. It
started booting, until:
fossil(#S/sdE0/fossil)... fsOpen: can't find /dev/sdE1/fossil ... panic
Does fossil store the device name somewhere on the disk? (The drive
was sdE1 when I formatted it.) How
that's a good question. if you just want to copy everything, i use the shell
idiom
disk/mkfs {echo +}
I ran this in /usr/bootes/ as bootes:
su# disk/mkfs -a -s / {echo +} arch
processing /fd/7
mkfs: /fd/7:1: can't open //dev/consctl: '//dev/consctl' permission denied
mkfs:
i think disk/mkfs is nearly idea for this, and isn't very dangerous. since
your
new fossil will start empty, you can't overwrite anything in the old fs.
How do I generate the proto file? Do I have to go through an archive?
Thank you for your patience.

Do you use Fossil with or without Venti?
There is many way to do it.
Without Venti, you could use replica(1) to copy your file system
from the old Fossil to the new Fossil.
Fossil without Venti.
Work has kept me busy but now I finally managed to attach the new
drive to the system. Plan9
I am about to upgrade the disk on my cpu/disk server to a bigger one,
and I want to maintain all the data. What is the most elegant way to
do this? The new disk is blank.
The wiki says The Plan 9 updates page contains an ANSI/POSIX port of
aux/vga that is useful only for dumping registers on various systems.
I am having trouble finding this tool. Any pointers?

disk is connected to the first SATA port on the motherboard.
Any insight would be greatly appreciated.
