Hello,<br>
<br>
Without specifying a rescue image, Nova will use the image that the<br>
instance is based on when performing a rescue.<br>
<br>
I've noticed that this is problematic for "cloud-friendly" images such<br>
as the official Ubuntu images and the newer CentOS 7 images. I'm finding<br>
that /dev/vdb still ends up mounted as /, most likely because of the<br>
common label name being found. This, of course, defeats the entire<br>
purpose of rescuing.<br>

Is there an easy way around this or is the best practice to specify an<br>
image tailored specifically for rescuing? And if that's the case, can<br>
anyone recommend a good rescue image that's already in qemu format?<br>

we have modified the cloud images to mount root fs from /dev/vda1 instead of UUID=something, we modified grub and /etc/fstab<br>
<br>
we also added a warning on /etc/rc.local. as some people run servers in rescue mode for a long time, and when the server was un-rescued they lost data and that's not cool.<br>
<br>
but we need to modify cloud images anyway to change repos, users, keys, etc. so is just one more step on our image build process.<br>
<br>
if is a minimal change you can download the image and run guestfish -a image.qcow2<span class="HOEnZb"><font color="#888888"><br>
