[9fans] Partitioning the disk

[9fans] Partitioning the disk

[Szymon Olewniczak]

Hi,
As I cannot force plan 9 to use my sata disk, I've decided to buy a sata to usb convertor.
After compiling the usb tools on 9atom, I can find my disk under /dev/sdU1.0 and now is the time to 
prepare the disk partitions in order to install plan 9. Disk which I want to use isn't empty
(it contains some of ext4s and swap) but I want to format the entire disk. In 9atom doc's pages
I've found some example how to initialize the blank disk:

Initialize the blank disk /dev/sdC0/data.
	disk/mbr –m /386/mbr /dev/sdC0/data
disk/fdisk –baw /dev/sdC0/data
disk/prep –bw –a^(9fat nvram fossil cache swap) /dev/sdC0/plan9
disk/format –b /386/pbslba –d –r 2 /dev/sdC0/9fat \
	/386/9load /386/9pcf /tmp/plan9.ini

And my question is: is it enough to create partitons for plan 9 installation? What sizes would have
9fat, nvram, fossil, cache and swap partitons? What should I do next after partitoning disk in order
to install plan 9 on it?

BTW. If there is any method to compile all the 9atom sources at once(simpler that writting rc script)?

BR,
Szymon

unfortunately usb disk devices are not directly partitionable.
this can be solved on 9atom with sdloop

	addloop u /dev/sdU1.0/data

this will create /dev/sdu0/^(ctl data) which you can then partition
with diskparts.  (if using the standard distribution use diskparts(8) and
the file will be /dev/sdXX/data)

if you do a pull as glenda, or alternately

	mount /srv/boot /n/root &&
		9fs atom && 
		disk/mkfs -vkU -s /n/atom/plan9^`{pwd} -d . <{echo +}

you can then try "mkusbboot -p `{echo +}".  this may actually work.
let me know if it has not, as i haven't had a chance to test it.

> BTW. If there is any method to compile all the 9atom sources at once(simpler that writting rc script)?

cd /sys/src; mk install && mk clean

there is not enough room on the usb key to install all.

It seems to me like an issue with internet connection. Am I right?
One more question to this command. You've used pwd in it, so what directory should I be in, in
order to run command successfully? Why do I need to run this first mount command(the /n/root seems
to be used nowhere)?

> there is not enough room on the usb key to install all.
The other problem is that after compiling usb and all it dependences when I've rebooted
the plan 9 atom all programs disappeared and I've needed to compile them again. Is there any method to
make the changes to the disk persistent?

yes.  you can either run ndb/dns -r and ndb/cs and then try again, or replace
"9fs atom" with

	attaip=208.71.233.235
	nflag=-n
	srv $nflag -q tcp!$attaip atom &&
		mount $nflag /srv/atom /n/atom atom

changes to the disk are persistent.  i suspect the executables are
misplaced.  are you booting from the hard drive?

But my ethernet device probably is not recognised. When I run ip/ipconfig I get:
	ipconfig: /net/ipifc/clone: bind ether /net/ether0: '/net/ether0' cs: file does not exist

It looks to me like the need of ordering a new ethernet card. I will try to order 8169 as you've recomended
and try to connect to the internet again.

I'm booting from pendirve which I've setuped as you described earlier(using dd). Maybe it's happening becouse
I turn off my computer by pressing power button.
How can I turn off plan9 in a clear way?

yup. i'll bet you compiled on the hard drive, and that's where the
executables are.  try booting without the pen drive.

No sadly it isn't true. But my question is: do I need the Internet
connection in order to mount atom image or can I install plan9 on my USB
disk without it?

i think it's more likely that they're in an location you're not
expecting.  then again, i've never installed to a usb disk.
at a minimum, you'll need to edit plan9.ini by hand.

you do not need an internet connection.

So maybe I should try something diffirent. I come up into idea to boot
plan9 from the network disk. Wouldn't the Linux workstation with the 9p
be enough to store all the plan9 files?

Hi,
I've bought a new ethernet card and finally I've the internet connection working :)
However, I'm still having problems with disk partitoning. I'm trying to initalize blank disk
as I have mentioned before(following preg(8) example) , using loopback as the erick suggested.
But I don't have any files such as:
/386/mbr
/386/9pcf
Where can I find them?

BR,
Szymon

Re: [9fans] Partitioning the disk

[erik quanstrom]

> /386/mbr

for pcf "cd /sys/src/9/pc; mk 'CONF=pcf' install".

Re: [9fans] Partitioning the disk

[Szymon Olewniczak]

I've some more questions to partitoning process in Plan9, I hope that after
solving them I will finally manage to partiton my disk successfully:

1. After mounting usb disk with addloop, there is no file /dev/sdU1.0/plan9. How
can I create plan9 partion table?

2. What does diskparts(8), actually do? Does it create partitons on phisical disk?

3. Is the inst/textonly avalible in 9atom or is it obsolete?

4. This whole partiton process seems very strange to me. How can I determine partiton
sizes during partinoning? Which files go where(as I can see there are at least two partition
types: fossil and 9fat)?

5. Thank you very much erik for your help but could you give me a little descripton on what
does the commands you've provided me supose to do?

Sorry, if this questions are to obvious to you but as a newbie I don't understand plan9
fully. I can already feel its power but I'm sitll not able to use it.

BR,
Szymon

diskparts reads existing paritition information from the disk, it does not write anything.

amd it's just a short rc(1) script, that typically runs "disk/fdisk -p data>ctl",
 and "disk/prep -p plan9>ctl".  with this setup prep is subpartitioning the
plan 9 partition.

it's worth a read.

> 3. Is the inst/textonly avalible in 9atom or is it obsolete?

textonly is not available in the 9atom usb install, but that doesn't mean it's
obsolete.

both prep and fdisk take the "p" command which will print the current partition info.
prep(8) is a good reference.  btw, "fossil" and "9fat" are not partition types.  prep doesn't
use that concept.  they are partition names, and by convention they have the obvious use.
