Never had this error before. From a quick search, it may be related to
hotplug/udev event processing. In which environment are you running this
command ? What happens if you add the option --noudevsync ?

-v just increases the verbosity, so it should not have any effect on
success or failure.

That's not a solution, just a workaround to avoid the wiping error.

Yes, if it is created correctly and active. Check with lvs, lvdisplay.
