LVM that have extends on the physical disk. That speeds it up, as the
extends are marked free again. How many disks do you now have in your
volume group? If only one, then simply try to copy the entire disk to
another one (dd/ddrescue/clonezilla). If the disk has bad sectors, then
the pvmove will most likely fail anyhow.
thank you for the reply. I have four disk in one LV. so yesterday I already done pvmove the 2TB disk and it took time about 20 hours. I think the disk is just start to fail and most part of the disk is still good, that's why the pvmove process didn't take time that long.
