.SH DESCRIPTION
|
|
pvscan scans all supported LVM block devices in the system for
|
|
physical volumes.
|
|
.SH OPTIONS
|
|
See \fBlvm\fP(8) for common options.
|
|
.TP
|
|
.BR \-e ", " \-\-exported
|
|
Only show physical volumes belonging to exported volume groups.
|
|
.TP
|
|
.BR \-n ", " \-\-novolumegroup
|
|
Only show physical volumes not belonging to any volume group.
|
|
.TP
|
|
.BR \-s ", " \-\-short
|
|
Short listing format.
|
|
.TP
|
|
.BR \-u ", " \-\-uuid
|
|
Show UUIDs (Uniform Unique Identifiers) in addition to device special names.
|
|
.TP
|
|
.BR \-a ", " \-\-activate " " \fIay
|
|
Together with the information already cached in lvmetad, automatically activate
|
|
any logical volumes that become activatable after the scan done on one or more devices.
|
|
The logical volume to autoactivate is matched against the
|
|
activation/auto_activation_volume_list set in lvm.conf. If this list is not set, then
|
|
all volumes are considered for autoactivation. The autoactivation is not yet
|
|
supported for logical volumes that are part of partial or clustered volume groups.
|
|
.TP
|
|
.BR \-b ", " \-\-background
|
|
Run the command in the background.
|
|
.TP
|
|
.BR \-\-cache " [" \-\-major " " \fImajor " " \-\-minor " " \fIminor " | " \fIDevicePath " | " \fImajor:minor " ]..."
|
|
Scan one or more devices and instruct the lvmetad daemon to update its cached
|
|
state accordingly. Called internally by udev rules.
|
|
All devices listed explicitly are processed \fBregardless\fP of any device
|
|
filters set using \fBdevices/filter\fP configuration setting. To filter
|
|
devices even in this case, the \fBdevices/global_filter\fP must be used.
|
|
If lvmetad has not yet cached any metadata or the filters have recently been
|
|
changed, then all devices may be scanned, effectively ignoring the rest of
|
|
the command line. Otherwise, if all the devices referenced on the command line
|
|
contain metadata in the default lvm2 format, other devices are not accessed.
|
|
If metadata written using the obsolete GFS pool format is encountered, this is
|
|
ignored and so lvmetad should not be used.
