Hi Jon,
I've applied the new deb files and added the primary disk entry to the
xensource-inventory file.
It looks like the error I had was related to the PRIMARY_DISK missing
setting.
I can now create a local SR, create a vdi, and a vbd, but if i try to
plug it to the dom0 (i've not configured any VM yet as I'm trying the
different storage layers) I get ugly kernel messages.
Here is what i've done:
box# xe sr-create content-type=user type=ext name-label=local
device-config:device=/dev/sda3
66597906-20ae-5ec6-e60a-e0dec55df506

box # xe vbd-create vm-uuid=03753e00-3514-296c-52e1-26ba8f1dd068
vdi-uuid=ca4ba7bd-2901-45fb-a3f5-18b7d78e0232 device=0 type=disk mode=rw
92a3b3bc-8b48-b13d-a53c-891c10fba1b9
box # xe vbd-plug uuid=92a3b3bc-8b48-b13d-a53c-891c10fba1b9
[hangs indefinitely]
doing a ctrl-c after one minute or so to get the shell back
Still, the device has been plugged as xvda appears in the dom0 and I can
fdisk it, mount it etc.
But there are not so nice messages in the dmesg, and If i try to attach
another vbd it doesn't work anymore.
dmesg:

Now, on the box I have open-iscsi/multipath/ocfs2 running. So I'm going
to try again with all that
stuff disabled to check if nothing is conflicting...
But, In the meantime if you have an idea ? :)
Thanks,
Sébastien

Looks like the EXTSR was a bit broken in a couple of ways.
Firstly, you'll need to add a 'PRIMARY_DISK' line to /etc/xensource-inventory
(now mentioned in the wiki page)
Secondly, the path the the LVM tools was incorrect. I've fixed this in a new
deb that I've uploaded to downloads.xen.org.
Thirdly, I've added to the instructions that LVM2 needs to be installed.
I've also fixed a bunch of other things in the debs that I've uploaded - please
pull down the latest versions and install them.

Hi,
Continuing my tests with xapi on debian, I get into an issue trying to
create a SR.
box# xe sr-create type=ext name-label=local device-config:device=/dev/sda3
Error code: SR_BACKEND_FAILURE_1
Error parameters: , Error reporting error, unknown key NoRootDev,
/usr/lib/xen-common/xapi/sm/util.py:17: DeprecationWarning: The popen2
module is deprecated. Use the subprocess module.
import os, re, sys, popen2, subprocess
Any idea what could be wrong ?
Thanks a lot for your help.
Sébastien
