Hi, 1) I have flavors like 1 vCPU, 2GB memory, 20GB root disk. No swap + no ephemeral disk. Then I just create an instance via horizon choosing an image + a flavor. 2) OpenStack itselfs runs on Ubuntu 12.04.4 LTS, for the instances I have some Ubuntu 12.04/14.04s, Debians and CentOS'. 3) In the spawned instances I see that the partition wasn't resized. /proc/partions + fdisk -l show the size of the image partition, not the instance partition specified by the flavor. --- original message timestamp: Tuesday, August 05, 2014 03:50:55 PM from: Jeremy Hanmer <jeremy.hanmer at dreamhost.com> to: Dinu Vlad <dinuvlad13 at gmail.com> cc: ceph-users at lists.ceph.com <ceph-users at lists.ceph.com> subject: Re: [ceph-users] Openstack Havana root fs resize don't work message id: <CAKRUTFCLV9GsimUYs+Hu-ygoboqNVUZACtWWtiP02- ch8QYqpw at mail.gmail.com> > This is *not* a case of that bug.
