Grow a lvm partition

[ixproxmox]

I have been really struggling with this and I don't know why. I have a lvm-partition /dev/sda3 that I use for storing the vm-machines and want to increase it due to expanded underlying disk.

I have added on disk to the system and expanded the disk from 3.49TB to 4.4TB and as you see, fdisk report the same.

I want this lvm partition (/dev/sda3) to grow to fill the disk. I'm able to create a new sda4 partition and create a lvm-group on that and I can of course create a lvm on top. But I really would like to just lvmgrow somehow. The /dev/sda3 should be increased to max. Why is it so difficult?

I have a hw raid array /dev/sda:

Disk /dev/sda: 4.4 TiB, 4798283776000 bytes, 9371648000 sectors
Disk model: MR9361-8i
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 262144 bytes / 1048576 bytes
Disklabel type: gpt
Disk identifier: 3377A156-57E0-4428-9079-3D86964DF8B6

Device Start End Sectors Size Type
/dev/sda1 34 2047 2014 1007K BIOS boot
/dev/sda2 2048 1050623 1048576 512M EFI System
/dev/sda3 1050624 7497318400 7496267777 3.5T Linux LVM

Partition 1 does not start on physical sector boundary.

Command (m for help): q

/sdb and /sdc is just some additional disks on the system not in real use.

1. create a partition on the remaining space on sda, eg /dev/sda4
2. pvcreate /dev/sda4
3. vgextend local-extra /dev/sda4
4. lvextend, xfs_growfs as necessary

Thanks, it looks like something I manage before, but shows two different paritions. But if I can pull ut off, maybe it can work..

root@px1:~# vgextend pve /dev/sda4
Volume group "pve" successfully extended

The volume group pve contains now to partitions.

When going into thinpool based on this volume group, it still shows 3.4TB. Is there a similar command for thinpool? It looks like the volumegroup pve now has free space as it should:
