Hi all,
I''d like to develop a new script for block-devices.
Where do I have to register it?
It''s for DRBD block devices. It''s called
''block-drbd'' .
I tried the following steps:
1) copy it in /etc/xen/scripts
2) register it in /etc/xen/xend-config.sxp :
# Setup script for drbd block devices
(block-drbd block-drbd)
3) use it in a domU config file:
...
disk = [ ''drbd:drbd0,hda1,w'' ]
...
So far, it doesn''t work.
Can anyone give me a hint?
Thx,
Mike

What version of Xen is this? For Xen 2.0, that looks correct. Xen 3.0 does things differently and I don''t know if it needs anything else (like, possibly extra hotplug rules???). Just a silly question: did you chmod +x the script?

This is out-of-date stuff from the pre-hotplug days. I removed these examples last week, in fact, so you may want to update your config file. These scripts are now called by the hotplug/udev infrastructure. There should be no need to register the script as such -- xen-backend.agent should be called by udev, and then that will call /etc/xen/scripts/block, which in turn will call /etc/xen/scripts/block-drdb. Have a look in your syslog files (particularly the debug level one, e.g. /var/log/debug) and maybe add some tracing to those files, to see where it gets stuck. You might also want to try PYTHONPATH=/usr/lib/python python /usr/lib/python/xen/util/diagnose.py <dom> which at least will tell you whether the store entries for the device have been created correctly.

Oh sorry, I forgot to mention. Yes, it''s for Xen 2.0.7. Hm, strange. I rechecked everything including execution permissions for the script. Now it works fine. Thought it wasn''t called, but I guess there was a problem with drbd. Thanks, regards Mike On Monday 24 October 2005 16:43, Mark Williamson wrote:> What version of Xen is this?

The hotplug/udev infrastructure support is for Xen 3.0, right? Because I downloaded the latest sources of Xen-stable last week. After rechecking all of my steps, it finally works fine :) Regards, Mike On Monday 24 October 2005 16:59, Ewan Mellor wrote:> On Mon, Oct 24, 2005 at 04:38:39PM +0200, Michael Mey wrote: > > Hi all, > > > > I''d like to develop a new script for block-devices. > > Where do I have to register it? > > > > It''s for DRBD block devices.
