| .SH 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 \fBlvm.conf\fP(5) to restrict |
| the scan to avoid a CD ROM, for example. |
| .LP |
| In LVM2, vgscans take place automatically; but you might still need to |
| run one explicitly after changing hardware. |
| .SH OPTIONS |
| See \fBlvm\fP(8) for common options. |
| .TP |
| .B \-\-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. |
| .TP |
| .B \-\-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. |
| .TP |
| .B \-\-cache |
| Scan devices for LVM physical volumes and volume groups and instruct |
| the lvmetad daemon to update its cached state accordingly. |
