Package: lvm2
Version: 2.02.66-5
Severity: important

lvrename fails to rename the COW partition associated with a snapshot:

  device-mapper: rename ioctl failed: Device or resource busy

Then if a rename is attempted to the name that should have previously been 
renamed away
(but returned EBUSY instead as above)

[  698.009267] device-mapper: ioctl: Unable to change name on mapped device 
debian-kvmraw--aurora.snapshot.old-cow to one that already exists: 
debian-kvmraw--aurora.snapshot.old2-cow

Further operations on the snapshot produce a hang in uninterruptible I/O state
which requires a reboot.
