I'm testing the patch set, but a log monitoring doesn't work properly.
When dmeventd detects an error, lvconvert is executed for its repair.
For example, in case that the mirror VG/LV name is vg00/lv00, lvconvert
was called with the following options:

lvconvert --config devices{ignore_suspended_devices=1} --repair \
          --use-policies vg00/lv00_mlog

However, lvconvert can't accept vg00/lv00_mlog because "_mlog" is
an reserved name. When lvconvert is executed by itself, the following
message is displayed, and no repair is done.

# lvconvert --repair vg00/lv00_mlog
  Names including "_mlog" are reserved. Please choose a different LV name.
  Run `lvconvert --help' for more information.

We need to escape from this restriction when "mirrored" log is used.

Thanks,
Taka
