Using LVM on a cinder volume exposes the data to the compute host

Solution Verified - Updated -

Issue

Using LVM on compute nodes. This can cause problems such as:

  • Conflicting VG names on the compute.
  • The LVM on the compute to adjust metadata that the instance is not aware of, leading to things like missing volumes.
  • Detaching could fail and maps could still be marked as still "in use" due to LVM attaching itself to the multipath device.
