Re: vgmodify help
When I do a vgmodify -tnv
Physical Extent zero is not free on all PVs. You will not achieve these
values until the first extent is made free (see pvmove(1M)) on all the
following disks:
So as per the doc, I have to free up the first extent on all the disks by doing a pvmove.

Re: vgmodify help
> Can you let me know if I do a pvmove command, will it remove any data or bring down the databases running on that VG.
A 'pvmove' can be used while the logical volume is in normal operating mode. However, do not interrupt the process as this can lead to a stale extent condition.
