unavailable/active spare
The physical volume is unavailable and it’s an active
spare. Thus, the data on this physical volume in una-
vailable.
unavailable/standby spare
The physical volume is a spare, "standing by" that is
not currently available to capture data from a failed
physical volume.
Allocatable Allocation permission for the physical volume
VGDA Number of volume group descriptors on the physical volume
Cur LV Number of logical volumes using the physical volume
PE Size (Mbytes)
Size of physical extents on the volume, in megabytes (MB)
Total PE Total number of physical extents on the physical volume
Free PE Number of free physical extents on the physical volume
Allocated PE Number of physical extents on the physical volume that are allocated to logical
volumes
Stale PE Number of physical extents on the physical volume that are not current
IO Timeout The I/O timeout used by the disk driver when accessing the physical volume. A
value of default, indicates that the driver default I/O timeout is being used.
Autoswitch Autoswitch behavior for multiported physical volumes accessed through multiple
paths. When set to On (default), LVM is directed to automatically switch to the
highest priority (as defined by the order of the paths in the /etc/lvmtab file) link
whenever it becomes available. When set to Off, LVM will only switch links
under manual instruction or when the current one fails.
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 infor-
mation 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 deter-
mined 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 contains the data that ori-
ginally resided on this volume. This information can be used to manually move
the data back to the original physical volume (see pvmove(1M)) once it has been
repaired.
Proactive Polling
(See WARNINGS section). LVM’s proactive polling of alternate links. When set
to On (default), LVM will periodically test alternate links and help to identify
faulty paths before user IO is affected. No periodic testing of alternate paths will
be performed when Proactive Polling is set to Off.
Display With −−vOption
If -v is specified, pvdisplay lists additional information for each logical volume and for each physical
extent on the physical volume:
--- Distribution of physical volume ---
The logical volumes that have extents allocated on pv_path, displayed in column format:
LV Name The block device path name of the logical volume which has extents allocated on
pv_path.
