Re: VGDA value

Hi,

Volume group reserved area (VGRA): created by the vgcreate command and contains the volume group status area (VGSA) and volume group descriptor area (VGDA), which contains device driver information used for the volume group.

Re: VGDA value

... you will usually see 2 per PV, a primary and a secondary on each disk.

For a mirrored disk pair the value is usually 4, for a single disk 2.

Hope this helps!
