Centos 7 image missing packages

I began to play with lxd recently and until today everything went smoothly, I created a bunch of centos/7 containers and used them. Today I tried to create a new centos/7 container and it had no packages at all!

ns pts/2#lxc launch images:centos/7 xyz
Creating xyz
Starting xyz
ns pts/2#lxc exec xyz /bin/bash                                                                  
[root@xyz ~]# rpm -qa
[root@xyz ~]# rpm -qa|wc -l
[root@xyz ~]#

If I create centos/6 container, all packages are there:

ns pts/2#lxc launch images:centos/6 xyz
Creating xyz
Starting xyz
ns pts/2#lxc exec xyz /bin/bash                                                                  
[root@xyz ~]# rpm -qa|wc -l

It seems that image refreshed today and something is broken. So how to a) notify somebody that image is broken and b) download previous image to continue creating new centos/7 containers?

I’m currently getting:

stgraber@castiana:~$ lxc launch images:centos/7 centos7
Creating centos7
Starting centos7
stgraber@castiana:~$ lxc exec centos7 bash
[root@centos7 ~]# rpm -qa | wc -l
[root@centos7 ~]# 

Kinda looks like the RPM database might have been corrupted in some version of the image or something? At least here the current centos7 image is fine.

Okay, I deleted image and recreated it again and now rpm database is fine. I just checked and it seems that btrfs storage is kinda low on space (yet, image re-download fit just fine).

May be some failure during out-of-space situation wasn’t detected?
