currently available to capture data from a failed physical
volume.
Total PE Total number of physical extents on the physical volume.
Free PE Number of free physical extents on the physical volume.
Current pre-allocated PE
Number of pre-allocated physical extents on the physical volume.
Note that this field is only displayed for volume group version 2.2 or
higher.
Spared from PV If the physical volume represents an active spare, this field will show
the name of the failed physical volume whose data now resides on this
spare. This information can be used to manually move the data back
to the original physical volume once it has been repaired (see
pvmove (1M)). If it cannot be determined which physical volume that
the data came from, this field will instead display
Missing PV.A
missing PV would indicate that when the volume group was last
activated or reactivated (see vgchange (1M)), the "failed" physical
volume was not able to attach to the volume group.
Spared to PV If the physical volume represents a failed physical volume, this field
will show the name of the active spare physical volume that now con-
tains the data that originally residing on this volume. This informa-
tion can be used to manually move the data back to the original phy-
sical volume (see pvmove (1M)) once it has been repaired.
Autoswitch For multiported devices accessed via multiple paths, this field indi-
cates the autoswitch behavior for the physical volume (see
pvchange (1M)).
On LVM will automatically switch from the path it is using
whenever a better path to the physical volume is available.
LVM will switch paths when a better path recovers (after it
had failed earlier), or if the current path fails and another
path is available. This is the default.
Off LVM will automatically switch to using the best available
path only when the path currently in use is unavailable.
LVM will continue using a specific path for the physical
volume as long as it works, regardless of whether another
better path recovers from a failure.
Proactive Polling This specifies LVM’s proactive polling behavior on alternate paths of a
physical volume.
On LVM will periodically test alternate paths of a physical
volume and help to identify faulty paths before user I/O is
affected. This is the default.
Off No periodic testing of alternate paths of a physical volume
will be performed.
--- Physical volume groups ---
Information about physical volume groups belonging to vg_name :
PVG Name Name of a physical volume group in the volume group.
PV Name The block device path name of a physical volume in the physical
volume group.
Compact listing (-F Option)
The
-F option generates a compact and parsable listing of the command output in colon separated fields
formatted as key=value[,value ...]. The -F option is designed to be used by scripts. The resulting com-
mand output may be split across multiple lines. The output may include new keys and/or values in the
future. If a key is deprecated, its associated value is set to NAM (key=NAM). For the current version of
the vgdisplay command, the lines format is:
