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

Thanks for posting. I was looking for a good definition of attribute bits, and this could not be better.

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.
