When using \fBudev\fP(7) to manage the /dev content, it is also highly recommended
to use the \fB--refresh\fP option. This way, the necessary udev events are
generated too and associated udev rules are properly applied. If the \fB--refresh\fP
option is not used in this case, then LVM recreates the /dev content directly and
udev will not have proper records about affected symlinks and nodes. Also,
any node permissions defined by udev rules are not applied. This, in turn,
may cause problems for other system components that rely on reading the udev
database to get the list of /dev symlinks and nodes and which rely on the
permissions based on udev rules.
