Hi guys, I have an openstack instance that run out of storage on core machine and the instance got paused. I cleared up the core machine so it has more disk now but when I start the machine I can't ssh in. In rescue mode I'm able to ssh in but I want to unrescue the machine to be able to use it

Hi Balazs, Have you tried connecting to the image via NBD (network block device). 1) Mount the image. 2) Repair/free some space. 3) Start the instance. http://blog.vmsplice.net/2011/02/how-to-access-virtual-machine-image.html Steve On 15/03/16 11:20, Tomas Vondra wrote: Balazs Varhegyi

Hi Steve, Thanks for the suggestion, I already managed to clear up some space in rescue mode (VM instance has 2,1T disk with 1T free space) and core machine has an extra 270G free disk too. Balazs On 15/03/16 13:56, Stephen Davies wrote: Hi Balazs, Have you tried connecting to the image via

[Openstack] Migrating images off compute node?

2016-03-15 Thread Ken D'Ambrosio
Hey, all. We're having some significant network issues in our Icehouse cloud, and I was wondering if there's a way to migrate quiescent VM images right off the compute node, and, if there is, if there'd be a problem migrating them to (say) Liberty. Thanks kindly, -Ken __
