Rsync would copy hidden files when recursing as a side effect of the -a
option. However, the shell is going to expand that '*' before rsync
sees the command line and miss any hidden files in the top level
directory. I'd probably have done:
cd /mnt/lvo100045
rsync -avH . /lvo00045
instead. That gives rsync a directory as a starting point without
having to remember the quirks of whether it will or won't create a
subdirectory of that name on the target. It also doesn't make sense to
use -z for a local file copy and you might need -H if you have
hardlinked files on the filesystem.
