Calling vgscan alone should reuse information from the lvmetad (if running). The --cache option should initiate direct device scan and update lvmetad appropriately (if running). This is mainly for vgscan to behave consistently compared to pvscan.

.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 for common options.
|
|
.TP
|
|
.I \-\-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
|
|
.I \-\-cache
|
|
Scan devices for LVM physical volumes and volume groups and instruct
|
|
the lvmetad daemon to update its cached state accordingly.
