how to check vg version in v2?

[Jupinder Bedi]

Check minor numbers for /dev/*/group
files.

# ll /dev/*/group

The minor number for volume group version 1.0
is ALWAYS 64.

The minor number for volume group version 2.x
is ALWAYS 128

#lvmadm -t

would tell you version.

While creating vg you can specify

vgcreate -V 2.0 -s X /dev/vgXX /dev/disk/diskXX

lvmadm command will not work in v2 it wil only work in v3

you don't need to check the lvm version in 11iv2 - it only has lvm v1.0

Hi,

How about print_manifest ? Does it show the version of the same. I dont have console to test the same now :)

check with vgdisplay ,, even if it is v2 or v3 u can find it in vgdisplay ..

in v3 u can use lvmadm to find the version.

vgdisplay -v [vgname]
