VGMKNODES(8) System Manager's Manual VGMKNODES(8) NAME vgmknodes - recreate volume group directory and logical volume special files SYNOPSIS vgmknodes [-d|--debug] [-h|--help] [--refresh] [-v|--verbose] [[VolumeGroupName | LogicalVolumePath]...] DESCRIPTION Checks the LVM2 special files in /dev that are needed for active logical volumes and creates any missing ones and removes unused ones. 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. See lvm for common options.

VGSCAN(8) System Manager's Manual VGSCAN(8) NAME
vgscan - scan all disks for volume groups and rebuild caches SYNOPSIS
vgscan [-d|--debug] [-h|-?|--help] [--ignorelockingfailure] [--mknodes] [-P|--partial] [-v|--verbose] DESCRIPTION
vgscan scans all SCSI, (E)IDE disks, multiple devices and a bunch of other disk devices in the system looking for LVM physical volumes and volume groups. Define a filter in lvm.conf(5) to restrict the scan to avoid a CD ROM, for example. In LVM2, vgscans take place automatically; but you might still need to run one explicitly after changing hardware. OPTIONS
See lvm(8) for common options. --mknodes Also checks the LVM special files in /dev that are needed for active logical volumes and creates any missing ones and removes unused ones. --cache Scan devices for LVM physical volumes and volume groups and instruct the lvmetad daemon to update its cached state accordingly.
