Help on replace larger disk

[Truong Chuong Duong]

I am not sure if some one answers this issue already but I cannot found any where saying about it, might it's because my poor English or searched wrong key words.

My problem is I installed Proxmox Virtual Environment 4.2 from an ISO file on a 2T harddisk.
I had just replace it by a 8T harddisk, I copied the 2T HDD to 8T HDD by the dd command.
Now the promox boot successfully but it look like only 2T are installed.
How can I increase the Proxmox disk to the new size?

I ran lvs and got

I tried lvextend -l+100%FREE pve/data but it says canot extend:

root@mland:/# lvextend -l+100%FREE pve/data
New size (447140 extents) matches existing size (447140 extents)
Run `lvextend --help' for more information.
​

Could some one can help me to know what happen?

Hi,

you have to create an new partition first then extend the vg(volume) and then you can extend the lv(logical volume).
