Title:
Race condition when deleting iscsi devices
Status in OpenStack Compute (nova):
Expired
Bug description:
If you have two instances on the same compute node that each have a
volume attached (using iscsi backend)
If you delete both of them triggering a disconnect volume the
following happens:
First request will delete the device
echo 1> /sys/block/sdr/device/delete
The second request triggers an iscsi_rescan which then rediscovers the
device.
The volume is then deleted from the backend cinder.
now you have a device which is pointing back to a deleted volume.
This is using an NetApp device where all the devices are in the same
IQN and using multipath on stable/havana
