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
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. SEE ALSO

vgreduce - reduce a volume group SYNOPSIS
vgreduce [-a|--all] [-A|--autobackup {y|n}] [-d|--debug] [-h|-?|--help] [--removemissing] [-t|--test] [-v|--verbose] VolumeGroupName [Phys- icalVolumePath...] DESCRIPTION
vgreduce allows you to remove one or more unused physical volumes from a volume group. OPTIONS
See lvm(8) for common options. -a, --all Removes all empty physical volumes if none are given on command line. --removemissing Removes all missing physical volumes from the volume group, if there are no logical volumes allocated on those. This resumes normal operation of the volume group (new logical volumes may again be created, changed and so on). If this is not possible (there are logical volumes referencing the missing physical volumes) and you cannot or do not want to remove them manually, you can run this option with --force to have vgreduce remove any partial LVs. Any logical volumes and dependent snapshots that were partly on the missing disks get removed completely. This includes those parts that lie on disks that are still present. If your logical volumes spanned several disks including the ones that are lost, you might want to try to salvage data first by acti- vating your logical volumes with --partial as described in lvm(8).
