I am wondering if there is a way to know which user created some cinder volume ?

$ cinder show volume_name

This shows only the tenant, and as you can guess the volume name is not very useful either...

Should I just search the logfiles, hoping there is still something in there ?

Edit:

Having a look at openstack code to eventually add the missing piece to show that info. It does not look like it's in python-cinderclient.

Now, if someone could give me a clue about where to look for, I'd be grateful...
