Description of problem:
This is the exact same message that is printed when an actual node leaves the
cluster (i.e. when recovery actually happens) so it's confusing/scary to also
see it when just deleting a volume.

[root@taft-04 ~]# lvremove /dev/mirror_1/deanmirror
Do you really want to remove active logical volume "deanmirror"? [y/n]: y
