No. Even rootdelay=20 does not solve this issue. Volume groups are
just not activated automatically and thus no active volume group is
found and system boots into emergency mode. Simple question is: where
and how are volume groups activated while booting? Any way to make
this system activate those volume groups and not just boot into
emergency mode? Any configuration files?
