Attributes Overview

In this KB, we will explorer LVM display attributes.  The LVM display attributes will help provide some insight into the status of your logical volumes and assist with determine if they are functioning correctly.

 

Logical Volume Attributes (lv_attr)

The lvs display attributes or lv_attr provide details into the status of the logical volume.  These attributes will help you determine if your volume / mirror / snap is online and functioning correctly.  We have include a diagram and table of this information for your convenience.

lv_attr Table:

[root@Linux01 ~]# lvs
LV VG Attr LSize Origin Snap% Move Log Copy% Convert
LogVol00 VolGroup00 -wi-ao 1.00G
[root@Linux01 ~]#


Bit #1
  • (m)irrored
  • (M)irrored without initial sync
  • (o)rigin
  • (p)vmove
  • (s)napshot
  • (S)napshot invalid
  • (v)irtual
  • (i)mage mirror
  • (I)mage out-of-sync
  • (c)onversion in progress
Bit #2
  • (w)riteable
  • (r)ead-only
Bit #3
  • (c)ontiguous
  • (n)ormal
  • c(l)ing
  • (a)nywhere
  • (i)nherited
Bit #4
  • (m)inor
Bit #5
  • (a)ctive
  • (s)uspended
  • (I)nvalid snapshot
  • (S)uspended snapshot
  • (d)evice present without tables
  • (i)nactive table on present device
Bit #6
  • (o)pen

 

From the above examples, we can see the lv_attr of '-wi-ao' tells us this logical volumes is:

  • Writeable
  • Inherited
  • Active
  • Open (mounted)


Volume Group Attributes (vg_attr)

The vgs display attributes or vg_attr provides details into the status of the volume group.  These attributes will help you understand the makeup and composition of the volume group.  We have include a diagram and table of this information for your convenience.

vg_attr Diagram:

vgs_attr

vg_attr Table:

[root@Linux01 ~]# vgs
VG #PV #LV #SN Attr VSize VFree
VolGroup00 1 5 0 wz--n- 9.88G 0
[root@Linux01 ~]#


Bit #1
  • (w)riteable

    •
  • (r)ead-only
Bit #2
  • resi(z)eable
Bit #3
  • E(x)ported
Bit #4
  • (p)artial
Bit #5
  • (c)ontiguous
  • c(l)ing
  • (n)ormal
  • (a)nywhere
  • (i)nherited
Bit #6
  • (c)lustered

 

From the above examples, we can see the vg_attr of 'wz--n-' tells us this volume group is:

  • Writeable
  • Resizeable
  • Normal



 

Physical Volume Attributes (pv_attr)

The pvs display attributes or pv_attr provides details into the status of the physical volumes.  We have include a diagram and table of this information for your convenience.

pv_attr Table:

[root@Linux01 ~]# pvs
PV VG Fmt Attr Psize PFree
/dev/sda2 VolGroup00
 lvm2
 a- 9.88G 0
[root@Linux01 ~]#


Bit #1
  • (a)llocatable
  • e(x)ported

From the above examples, we can see the pv_attr of 'a-' tells us this volume group is:

  • Allocatable

This is helpful, but is there a way to set the the pv_attr to Allocatable. Basically we exported BCV's to a box and I can't mount them to the box.

Is there a chart for Volume Group attributes as well? I've issued the vgs command and am not sure how to interpret. Thanks.
