pvscan scans all supported LVM block devices in
the system for physical volumes.
See lvm(8)
for common options.
- -e,
--exported
- Only show physical volumes belonging to exported volume groups.
- -n, --novolumegroup
- Only show physical volumes not belonging to any volume
group.
- -s, --short
- Short listing format.
- -u, --uuid
- Show UUIDs (Uniform Unique
Identifiers) in addition to device special names.
- -a, --activate ay
- 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.
- -b, --background
- Run the command in the background.
- --cache [--major
major --minor minor | DevicePath | major: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 regardless
of any device filters set using devices/filter configuration setting. To
filter devices even in this case, the devices/global_filter 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.
