i don't think you can put your configuration in the
same place you put your fs.

i think the superblock's tag is getting written to the
configuration area.

you can use my fs tree from sources which supports
a cec console.  you should be able to capture output
with it.

// i don't think you can put your configuration in the

That's at least not globally true, although maybe it
depends what you mean by "your fs". I have:
	config w4
	filsys main cw4[w<0-3>]
and it works fine. I've not checked to see if the cache
device leaves space that the (pseudo-)worm doesn't.

Certainly it's worth trying sticking the config
elsewhere, and getting a remote, loggable console is
a huge win.

And this should be obvious, but bears repeating given
the consequences: when you say you're looking to
recover an old setup, you know not to ream disks with
data you care about, right?

[9fans] Can't ream fs. Panic: config io

[g.pavelcak]

Hi,

I've been trying to recreate a plan9 file server I had expecting to eventually recover the old setup; however, I can't get past reaming a single disk.

Config goes like

service pinky
config w0
filsys main w0
ream main
end

I don't have anything set up to capture output, but I hope I can give you enough here. It looks something like

drive w0
   35885393 blocks at 512 bytes each
    2242834 logical blocks at 8192 bytes each
    16 multiplier
    tag = 0/0; expected 0/10 not flushed

stack trace of 2
...
panic: config io
cpu 0 halted


Any thoughts??

Thanks.

Greg
