I have a file server running Linux at home, with a normal ext3 file system
and a plan9port venti. I use this venti for vac backup of both the ext3
file system and other Linux boxes. However, the 2 TB ext3 is running out of
space, while the venti is roughly 50% full. I could just buy a bigger disk,

I use Sam mostly for the remote editing facility, but I should perhaps try
to add plumber rules to use a remote 'B' command to trigger opening the
files from the remote machine like James A. Robinson mentioned. Apart from
that, acme is my main command center. I usually have acme straddling two

This is great news. I am thinking of using the Pi3 to control a mobile
platform, and having wifi support without using an external wireless router
would simplify the hardware.

I think there was a port of gcc at one time. It should be possible to use
that to port later versions of gcc.
Go is already ported, AFAIK, but I have not yet found an excuse to try it
out.

Yes, I have been running a venti at home for some years, and a much smaller

I would be careful with running Venti on a SD card. Venti eats SD cards,
USB sticks and even SSD disks for breakfast, since the index is heavily
modified, and will rot after a while. Your actual data (arenas) will be
fine, though, so you can recover by rebuilding the index somewhere else.

Based on copy.c and readlist.c, I have cobbled together a venti client to

Hmm. On both my plan9port and on a 9front system I find printarenas.c, but
no script. Maybe you are thinking of the script for backup of individual
arenas to file? Yes, that could be a starting point.
Anyway, printarenas.c doesn't look too scary, basically a loop checking all
(or matching) arenas.
Thanks for the tip about mounting with 9fs. I have used vacfs on Linux ,
though.
But why so slow? Did you import a root with lots of backup versions? It was
partly because of that I made this client which can import venti blocks
without needing to traverse a file tree over and over again.

No printarenas there on my (9front) system, though. I'll have to see on a
proper plan9 system, maybe.

I can understand that it cannot fill up. What I do not understand is why
there are no safeguards in place to ensure that it doesn't. (And my inner
geek wants to know)
As you say, in reality it will not fill up unless you dump huge amounts of
data on it at once. Unfortunately, this is just what I in

Yes, you better have high-endurance SSD's. I put the venti index at work on
an ordinary SSD, and it lasted six months. The log itself was fine, of
course, so I only had to rebuild the index to recover. This was plan9port
on Solaris, btw.
Now this venti runs on an ordinary disk, the speed is less, b
Strictly speaking, isn't venti just content-addressable block storage, not
a file system? Anyway, I'm curious to know what you are going to use this
for.

I don't know either, but when I tried flfmt with a vac score as an

Here is a pointer to a discussion on comp.os.plan9, but I did not really
get a clear understanding of whether it was possible or not. It seems to me
that it was possible at some time, but based on my own findings, changes to
the format may have made vac and fossil incompatible.

The problem is the index. It is heavily updated, and I had a Fossil
installation that ate my SSD in about 6 months. The log was OK, so I could
rebuild the index on another disk.

Can't give a definitive answer, but it works fine on my Norwegian keyboard
which also has a rather different layout from the US keyboard. Unless the
key code is simply not handled, I can't imagine why you get nothing at all.

I think the text that is selected and sent by button 3 is hard-coded in
acme, so the square brackets acts as delimiters. If you click on the text
to the left of the brackets, the plumber will not see the brackets or

I think I agree. Besides, drawterm isn't that bad even over high-latency
VPN. I experimented a bit by running drawterm at work against a plan9

over X using the same connection. Of course, Emacs IS notoriously bad at
this...

We need to allow character devices as well, not just block devices:

I agree with you that using the existing tag mechanism to keep multiple

not readily supported by the higher level libraries, though.

Very interesting. In the past, I have resorted to using a combination of

On linux, you can run ctags -x and postprocess the file to append the line
number to the file name instead of having i as a separate field. That way,
you can locate the symbol in the tags file, and right-click on the
file:linenumber.
Also, on linux, we have acme-lsp, which in principle works with

I just stumbled across this thread, so I will repost something I wrote in
2017 about mirroring of venti. I had the need to create the union of two
venti servers, so I wrote a client that copies individual venti blocks,
given the scores. This you can do without worrying about what is on the
