Can't get the OS list

[Coalescence]

Hi all, I'm having trouble creating instances.

vmserver01:~# gnt-os list
Can't get the OS list

vmserver01:~# gnt-instance add -t drbd -s 1G -n vmserver01:vmserver02 -
o debootstrap tester
Failure: prerequisites not met for this operation:
OS 'debootstrap' not in supported os list for primary node

It's a fresh install and I'm pretty certain everything is setup right
(I deleted the drbd resources, rather than skipping them, is this
right?)

I followed the instructions to the letter, this is on x64 Debian Lenny
b.t.w.

Any help greatly appreciated!

Hi,

For this case there is the command "gnt-os diagnose". What does it tell
you?

Can't get the OS list

Same thing :(

[Iustin Pop]

OK, that means you don't really have any OSes. What is your OS path?
(Unfortunately gnt-cluster info doesn't tell you, you have to check in the file
_autoconf.py for OS_SEARCH_PATH, I'll file a bug about this).

And then, what do you have in those directory(es)?

vmserver01:/# cat /usr/local/lib/python2.5/site-packages/ganeti/
_autoconf.py | grep OS
OS_SEARCH_PATH = ['/srv/ganeti/os']

There's nothing at all in this path...

vmserver01:~# echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

Well, there is where you need to install the deboostrap OS, under
/srv/ganeti/os/[debootstrap/create, import, export, etc.].

Could you point me to the documentation for this please?

Ahh, I have found the files in /usr/local/share/ganeti/os

vmserver01:/usr/local/share/ganeti/os# cp -r debootstrap/ /srv/ganeti/
os/

That seems to want to work, however now I'm getting..

vmserver01:/usr/local/share/ganeti/os# gnt-instance add -t drbd -s 1G -
n vmserver01:vmserver02 -o debootstrap tester

Oh well, one down.. more to go! :)

[Coalescence]

Fully resolved.. I needed to add

usermode_helper=/bin/true

to the /etc/modules drbd line

[Iustin Pop]

Good to hear :)
