:'-(... Thanks to clarify the situation, so in our case with centos (we use cloudlinux that is based on centos), I suppose that only lvm is posible to resize online...Nice, don't works on CentOS. Tested with other kernels and programms. ;( Love my Ubuntu
Tested on Gentoo and Debian, works also fine.
[SOLVED] LVM or EXT4 on KVM guest?

Unfortunately, you still have not understood that LVM has the same problem. You have to resize the physical volume which lies in a partition (if you use it on a partition) and have the exact same problem: You cannot resize the volume online.
With lvm, I can add without any problem an disk, and extend volume using this new disk... I have test it and work without any problem in centos7...
Yes, that's right. I talked about resizing/expanding an existing disk. Sorry, I thought we are still talking about that. Adding another one is of course always possible and better with LVM.
Don't worry, this is effectively 2 distinct things... so, in centos :
- There is absolutely no way to expend online an partition on same disk (no in ext4 and no in lvm), only can be done offline by iso gparted for exemple.
- The only option to do it online (is what I have tested yet in some VM), is have an LVM system, add disk (not increase space of an used disk) and expend LVM volume using this disk.
Thanks to you help @fireon and @LnxBil I know now the real option that we have!
