Hi All, Running 2013.2.2 on Ubuntu 12.04. I've recently notices some (10% ish) of my compute node exhibiting unusually large "system' cpu utilization over the past few days.
Looking a little more closely I see that there are a number of 'qemu-nbd -c' process trying to connect deleted instance drives (files on local non-shared disk). Some of the instances referenced have been deleted as long ago as March 31 though most are in the past couple of days. 'qemu-nbd -d' seem the logical opposite of the running command and exits successfully telling me it has detached the device, but the original "-c" process is still running. kill -9 is effective, but I wonder if anyone else has seen this and how these odd orphans can be prevented, or has a pointer for where I might start looking for the culprit. Thanks, -Jon _______________________________________________ Mailing list: http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack Post to : openstack@lists.openstack.org Unsubscribe : http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack
