snapshot-temp-directory

hello fellow openstack users,

I just tried to create a snapshot of a virtual machine, which was larger
than average. Bad news: The snapshot couldn't be saved, but what I see
here is some kind of design problem:

2012-08-13 13:44:41 DEBUG nova.utils
[req-a678e738-9c18-4ee6-8e2e-f1f176a4674b

/usr/lib/python2.7/dist-packages/nova/utils.py:219

that's bad, I don't have so much disk space on /, but I have plenty in
/var/lib/nova/instances.

df -h | grep nova
/dev/dm-8 1.4T 150G 1.3T 11% /var/lib/nova/instances

is there a generic way to change this path?

Re: snapshot-temp-directory [In reply to]

This actually was fixed in upstream (
https://github.com/openstack/nova/commit/70129ed19db187cc90f74abd5c93c86098d29c27
).

Which OpenStack version you use?
Maybe this patch can be backported there.
There is workaround for this problem, but it's (not a bit) ugly:
