When CBT is disabled the CBT log is deleted, on the coordinator, when using shared LVM SRs it is necessary to inform the supporter of this change so that it can remove all information relating to the CBT log volume from the kernel device mapper table. If this is not done a subsequent CBT enable for this VDI will fail if the device mapper table still contains information about the previous, and now deleted, volume.
