Code:

1.#umount /dev/vg/a
2.#umount /dev/vg/b
3.#umount /dev/vg/c

Resize PV with the following command,

Code:

#pvresize /dev/sdb1(will this shrink the dev?)


pvdisplay /dev/sdb1 

lvextend -L +30G /dev/mapper/vg_ftpdata-lv_a
lvextend -L +30G /dev/mapper/vg_ftpdata-lv_b
lvextend -L +30G /dev/mapper/vg_ftpdata-lv_c


#mount /dev/vg/a
#mount /dev/vg/b
#mount /dev/vg/c

Kindly confirm.Thanks

If it can it will reconfigure how the pv sees the size of device to the correct size. Nothing is done to the /dev/sdb1

lvextend -L +30G /dev/mapper/vg_ftpdata-lv_b
lvextend -L +30G /dev/mapper/vg_ftpdata-lv_c

I do not know where those come from, everything you have shown says that it should be:

Code:

lvextend -L+30G /dev/mapper/vg-a
lvextend -L+30G /dev/mapper/vg-b
lvextend -L+30G /dev/mapper/vg-c

Code:

lvextend -L+30G /dev/vg/a
lvextend -L+30G /dev/vg/b
lvextend -L+30G /dev/vg/c

Note: Do not forget that you have to resize the file system, afterward, to recognize the new space, but I have not mentioned that since it is another topic that I assume you know about it.
