strange, it get to about 2% and then has hundreds on no file found errors. When I run the script again and choose official PPA it takes me straight back to the main menu, the PVR PPA seems to work though (spoke too soon as after entering additional pacakes and xbmc password screen it downloads something for about 10secs and then bck to main screen again)

The log contains lots of permission errors:

hmm strange, I'll look into that. think the process aborted somewhere while running and didn't umount properly.

could you pastebin the log up till the errors please?

before trying again, do this:

Code:
sudo umount /var/lib/xbmc-diskless/target/sys

sudo umount /var/lib/xbmc-diskless/target/proc

sudo umount /var/lib/xbmc-diskless/target/dev

sudo rm -rf /var/lib/xbmc-diskless/target

thanks for reporting this issue.

opdenkamp · 2010-10-29, 19:25

found a bug that prevents /target/dev from umounting sometimes. I'll add some more checks in the next version.

opdenkamp · 2010-10-30, 19:49

a new version has been published

fixes:

added some more checks
improved error handling
improved logging
the "installation gauge" is more precise now
fixed mount checks
limit rm with --one-filesystem so /dev can't be removed accidently
some cleanups

opdenkamp · 2010-10-30, 19:51

@Anastrophe:
please try again with this package and pastebin the log if it still fails.

harryzimm · 2010-10-30, 20:07

This is great. Thanks for sharing Smile

Im going to give it a go tonight. I'll let you know how i get on.

cheers

opdenkamp · 2010-11-02, 01:09

Little bug: the provisioning files are going to the wrong directory (/var/lib/xbmc-diskless/overlay instead of /var/lib/xbmc-diskless/overlay/provision).

bugfix build will be online within an hour

Awesome idea and thanks for your work to say first, i tried to get this up and running but I'm no advanced linux user. I set up the whole thing on my lucid server with the dnsmasq script posted here, the clients recognize the server but times out it seems, the daemon.log shows me this

I guess i have to adjust some permissions to the tftpd? Can someone point me in the right direction?

I removed the quiet and splash from the /var/lib/tftpboot/pxelinux.0
to see whats going on, it looks like its start loading the kernel and get's a 'connection refused on ndb mount' maybe this helps a little more debuging this.

vikjon0 · 2010-11-07, 23:15

Quote:the clients recognize the server but times out it seems, the daemon.log

Not sure what the problem is or if there are any specific requirements in this setup.
Generally I have noticed that dnsmasq is a bit sensitive how the menu is setup:

Quote:pxe-service=X86PC, "Boot from network", pxelinux

etc.

If you edited that, start over with the sample.

mason · 2010-11-07, 23:43

I guess I'm a step further, It's stopping with a 'connection refused' when the nbd is trying to mount the root fs....

opdenkamp · 2010-11-07, 23:46

what does "xbmc-diskless.sh check" say?

mason · (This post was last modified: 2010-11-08, 00:01 by mason.)

everything looks good

xbmc-diskless.sh check
Loading the default configuration
Checking your configuration:
image present: yes
inetd running: yes
tftpd running: yes
tftpd (69) listening: yes
nfsd running: yes
mountd running: yes
statd running: yes
portmap running: yes
/etc/exports has overlay: yes
portmap (111) listening: yes
nfs (2049) listening: yes

I tried telneting into port 2000 from the nbd... working

Oh wait, just noticed somehow it tries to connect to 192.168.1.1 which is my router, i guess this have something to do with the dnsmasq... I'll see if I could add the host somehow to the config !?

opdenkamp · 2010-11-08, 00:09

this is also wrong:

Code:
Nov  7 21:49:43 GATE dnsmasq-dhcp[3370]: 791112278 bootfile name: /var/lib/tftpboot/pxelinux.0

by default, xbmc-diskless pxe boot files are installed in /var/lib/tftpboot/xbmc-netboot. you're probably serving the wrong file. you should change that in the dnsmasq config too.

edit:
nvm that, they're not installed there anymore. I removed that from the global config a while ago Smile

mason · 2010-11-08, 00:21

I guess i wouldn't be able to boot anything if the pxelinux.0 file wasn't found.

I don't get it...

opdenkamp · 2010-11-08, 01:11

I'll make it a bit more verbose, let it tell where it's connecting to.

try this in the meantime and see if you can connect:
add "break=Xnbd" to the kernel parameters and reboot your diskless box.
it'll break the booting process just before mounting the nbd root

type this in the console:

Code:
mkdir /rofs

nbd-client xxx.xxx.xxx.xxx 2000 /dev/nbd0

mount -o ro -t squashfs /dev/nbd0 /rofs

replace xxx.xxx.xxx.xxx by the ip of your server.

if that works, see if you can ls /rofs and if your root shows up.
