Hello all we are testing openstack queens cinder driver for Unity iscsi (driver cinder.volume.drivers.dell_emc.unity.Driver).
The unity storage is a Unity600 Version 4.5.10.5.001
We are facing an issue when we try to detach volume from a virtual machine with two or more volumes attached (this happens often but not always).
We also facing the same issue live migrating a virtual machine.
Multimaph -f does not work because it returns "map in use" and the volume is not detached.
Attached here there hare nova-compute e volume logs in debug mode.
Could anyone help me ?
