vgscan (8)
NAME
vgscan --- scan all disks for volume groups and rebuild cachesSYNOPSIS
vgscan [--commandprofile ProfileName] [-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.
