Also for addressing "leaked invocation" warning messages, these message are seen (if the file discriptors are not one of 0,1,2), from `man lvm`:

"
On invocation, lvm requires that only the standard file descriptors stdin,
stdout and stderr are available. If others are found, they get closed and
messages are issued warning about the leak.

"
I would recommend trying to set `export LVM_SUPPRESS_FD_WARNINGS=1` as a workaround to suppress these warnings.
