vgmknodes [-d|--debug] [-h|--help] [--refresh] [-v|--verbose] [[VolumeGroupName|LogicalVolumePath]...]
Checks the LVM2 special files in /dev that are needed for active logical volumes and creates any missing ones and removes unused ones.
See lvm(8) for common options. --refresh
If any logical volume in the volume group is active, reload its metadata. This is not necessary in normal operation, but may be useful if something has gone wrong or if you’re doing clustering manually without a clustered lock manager.
