that's because the global_filter in /etc/lvm/lvm.conf, as a workaround you can manually add loop2 to filter dict.

[Zhenzan Zhou (zhenzan-zhou)]

Do you know who occupied /dev/loop0 and /dev/loop1? It seems that your previous devstack install added loop0 and loop1 in /etc/lvm/lvm.conf but not cleaned. And this run of stack.sh is trying to use loop2.

Thanks Zhenzan Zhou (zhenzan-zhou)
./clean.sh does not clean every thing from previous install?

[Zhenzan Zhou (zhenzan-zhou)]

From your log, /dev/loop0 is used by someone else, so the first VG uses /dev/loop1 and the second uses /dev/loop2. Please notice the WARNNING, you should check /etc/lvm/lvm.conf, find out global_filter and check its value. Normally after a successful install, it should have such line:

global_filter = [ "a|loop0|", "a|loop1|", "r|.*|" ] # from devstack

clean.sh should remove this line but something bad may happen.

From your log:

I just want to put my two cents on this. I have found the ./clean.sh script will fix the issue only if you specify DEFAULT_VOLUME_GROUP_NAME=stack-volumes-default in your local.conf
