VGSCAN(8)VGSCAN(8)NAMEvgscan - scan all disks for volume groups and rebuild caches
SYNOPSISvgscan [-d|--debug] [-h|-?|--help] [--ignorelockingfailure] [--mknodes]
DESCRIPTIONvgscan 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.
See lvm(8) for common options.
Also checks the LVM special files in /dev that are needed for
active logical volumes and creates any missing ones and removes
Scan devices for LVM physical volumes and volume groups and
instruct the lvmetad daemon to update its cached state accord‐
