Comment 2 for bug 1247901

Alex,

The environment we were running in was using iSCSI from a Linux based control node. The volumes were on LVM.

We started seeing the attachments fail intermittently, after about an hour, with:
raise exception.NotFound(_('Unable to find a mounted disk for '
                                                     'target_iqn: %s') % target_iqn)

The person who has access to the system where this is happening is out on vacation right now. So, I can't get you a pastebin right now. I have a patch written up. We ran with the patch for 7 hours without seeing the problem recreate.

Is this type of patch the sort of thing you expect to have a unit test as well?
