to capture data from a failed physical volume.
unavailable
The physical volume is unavailable and is not a spare physical
volume.
unavailable/data spared
The physical volume is unavailable. However, its data now resides
on an active spare, and its data is available if the active spare is
available.
unavailable/active spare
The physical volume is unavailable and it’s an active spare. Thus,
the data on this physical volume in unavailable.
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
Current pre-allocated PE
Number of pre-allocated physical extents on the physical volume that are
allocated to logical volumes. Note that this field is only displayed for
volume group version 2.2 and higher.
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 automati-
cally 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 information can be used to manually move the data back to the ori-
ginal 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 indi-
cate 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 originally 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 I/O is affected. No periodic test-
ing of alternate paths will be performed when Proactive Polling is
