Expanding Partition on Linux [en]

linux2

Expanding a partition on Linux (Virtualization) typically involves a few steps. Here’s a guide on how to do it using the parted utility. Before proceeding, make sure you have backups of important data, as resizing partitions carries some risk.

For LVM

Rescan Disk without restart machine

sudo echo 1>/sys/class/block/sda/device/rescan

Check Disk space after expanding partition on same disk
```
sudo fdisk -l #used for list all disk
```
if there are red text on the list, just type w for rewrite block, there are no affected to file inside partition.
Use parted to Resize Partitions
- Check Partition Layout
```
sudo parted /dev/sdX print
```
  Replace /dev/sdX with the appropriate device name for your disk (for example, /dev/sda).
- Resize the Partition
```
sudo parted resizepart X 100% 
```
  this command resizes partition X (we can just change X with partition number ex: 1 or 2 etc) to use 100% of the available space.
Check Physical Volume Status (PVS) on LVM
```
    sudo pvs
```
Resize the Physical Volume
```
    sudo pvresize /dev/sdXY

    sudo pvdisplay /dev/sdXY
```
this first command used for resize the physical volume and the second one used for show PV data size

Replace /dev/sdXY with the appropriate device name for your disk (for example, /dev/sda3).
Check Logical Volume Status (LVS)
```
    sudo lvs
```
Expand the Logical Volume
```
    sudo  lvresize -l +100%FREE /dev/mapper/ubuntu--vg-ubuntu--lv
```
Replace /dev/mapper/ubuntu–vg-ubuntu–lv with your LVM name.
Resize the the volume
```
    sudo resize2fs /dev/mapper/ubuntu--vg-ubuntu--lv
```
Replace /dev/mapper/ubuntu–vg-ubuntu–lv with your LVM name.

For Dedicated Mounted Drive

Rescan Disk without restart machine

sudo echo 1>/sys/class/block/sda/device/rescan

Check Disk space after expanding partition on same disk
```
sudo fdisk -l #used for list all disk
```
if there are red text on the list, just type w for rewrite block, there are no affected to file inside partition.
Use parted to Resize Partitions
- Check Partition Layout
```
sudo parted /dev/sdX print
```
  Replace /dev/sdX with the appropriate device name for your disk (for example, /dev/sda).
- Resize the Partition
```
sudo parted resizepart X 100% 
```
  this command resizes partition X (we can just change X with partition number ex: 1 or 2 etc) to use 100% of the available space.
Resize the the volume
```
    sudo resize2fs /dev/sdXY
```
Replace /dev/sdXY with your LVM name.
