NAME¶
vgscan — scan all disks for volume groups and rebuild caches
SYNOPSIS¶
vgscan [--commandprofile ProfileName]
[-d|--debug] [-h|-?|--help]
[--ignorelockingfailure] [--mknodes] [--notifydbus]
[-P|--partial] [--reportformat
{basic|json}] [-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.
- --notifydbus
- Send a notification to D-Bus. The command will exit with an error if LVM
is not built with support for D-Bus notification, or if the notify_dbus
config setting is disabled.
- --cache
- Scan devices for LVM physical volumes and volume groups and instruct the
lvmetad daemon to update its cached state accordingly.
