Since LVs can be referenced in a way that contains dashes, I expect dashes
may not be allowed.
See these examples:
/dev/vgname/logvolname
/dev/mapper/vgname-logvolname
But the following excerpt from "man lvm" doesn't support my thought.
VALID NAMES
The following characters are valid for VG and LV names: a-z A-Z 0-9
+ _ . -
VG and LV names cannot begin with a hyphen. There are also various
reserved names that are used internally by lvm that can not be used as
LV or VG names. A VG cannot be called anything that exists in /dev/
at the time of creation, nor can it be called '.' or '..'. A LV can‐
not be called '.' '..' 'snapshot' or 'pvmove'. The LV name
may also not contain the strings '_mlog', '_mimage', '_rimage', '_tdata',
'_tmeta'.

Underscores work just fine.
You might consider using underscores instead of dashes.

As maxxik suggests, you may consider escaping the hypen/dash.
