Sorry, that was my mistake - this is true for regexes, but since LVM2
filter regexes have an implicit ".*" at beginning/end (unless you use
anchors - see the comments in the default lvm.conf) and the '*' will
match 0 or more occurrences of the preceding character, it actually
behaves as though there is no '*' there at all.
E.g. "/sdlm*/" would match sdl$ANYTHING, since "m*" is matched by zero
occurrences of 'm' and the remaining string is consumed by the implicit
".*" at the end.
Regards,
Bryn.
