Definitely the low 1.20.x releases had a couple issues especially with containers. These were all fixed later, as Mark mentioned. Hopefully that'll solve your problems. <div class="gmail_quote">On Nov 15, 2014 1:02 PM, "Mark Shuttleworth" <<a href="mailto:mark@ubuntu.com">mark@ubuntu.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">On 14/11/14 02:39, Sameer Zeidat wrote: > Hello, > I'm running juju 1.20.1 on a test maas cluster.

I don't want to destroy it as I have some service deployment scripts that rely on machine number (using --to # deployment option). > Appreciating your help. > Hi Sameer A range of those 'pending' container issues were fixed during the set of releases from 1.20.1 to 1.20.11. I think it would be worth your updating to the latest 1.20 release. If you're on Ubuntu, add this to your /etc/apt/sources.list: deb <a href="http://ppa.launchpad.net/juju/stable/ubuntu" target="_blank">http://ppa.launchpad.net/juju/stable/ubuntu</a> trusty main That should give you 1.20.11. Let us know if you still see any issues with containers getting stuck on the way up. Also, it's a great idea to be able to nuke-and-retry in the event that this does happen, I'll find out if we have a nice way to add that regardless (a stuck container might happen thanks to cosmic rays, we should have an escape mechanism). Ideally, Juju should detect the issue and nuke the container, trying again on your behalf.
