# 🛠️ Fix LVM Disk Space Issue on Ubuntu
When you run `lsblk` and see a large disk (e.g., 3.2TB), but `df -h` shows only a few GB (e.g., 2.7GB), you might be using **LVM** and not utilizing the full disk space.
This guide shows how to extend the logical volume and filesystem to use all available space.

## 🧠 Problem Summary
- `lsblk` shows full disk size:
- But `df -h` shows:
---
## ✅ Solution: Extend LVM Logical Volume and Filesystem
### ️Step 1: Confirm the correct LV name using:
Run:
```bash
lvdisplay
```
### Step 2: Let's extend it to use all the free space using volume group and LV names:
```bash
lvextend -l +100%FREE /dev/datastore/LOG
```
### Step 3: After resizing the logical volume, resize the filesystem:
```bash
resize2fs /dev/mapper/datastore-LOG
```
Now run `df -h` again to check if the disk space has been extended..
