Bug#871817: [lvm2] --mirrorlog is not accepted for mirrored volumes

[mirq-deboogs at rere.qmqm.pl]

Package: lvm2
Version: 2.02.168-2
Severity: important

--- Please enter the report below this line. ---

lvcreate and lvconvert don't allow specifying --mirrorlog/--corelog
when creating/modifying mirrored LV.

# lvcreate -L 256m -n test -m 1 --nosync --mirrorlog core araid
--mirrorlog is supported only with mirrors.
  Run `lvcreate --help' for more information.

# lvcreate -L 256m -n test araid
  Logical volume "test" created.
# lvconvert -m 1 araid/test
  Logical volume araid/test successfully converted.
# lvconvert araid/test -m 1 --corelog
  --corelog and --mirrorlog are only compatible with mirror devices
