How to edit partitions on Linux after upgrading the VPS plan?

If you installed the system yourself and are using LVM, the general procedure is as follows:

We do not modify existing partitions, but instead create a new partition via fdisk (eg sda2).
After adding the partition, restart the VPS.
Now you add the new partition (here sda2) to LVM, the commands are approximately the following and may vary individually:
1. Initialization of sda2 partition for use with LVM, sda2 - new partition created by fdisk
```
							pvcreate /dev/sda2
						
```
2. You can find out the name of the group you want to extend by using the lvs - VG column command
```
							vgextend GROUP /dev/sda2
						
```
3. The unit name can be found in the same way as the group - column LV
```
							/dev/mapper/GROUP-UNIT
						
```
4. Extension about 15 GB
```
							lvextend --size +15G /dev/mapper/GROUP-UNIT
						
```
5. Inflating an existing filesystem over LVM
```
							resize2fs /dev/GROUP/UNIT
						
```
  For CentOS with XFS, however, resize2fs cannot be used, so it is necessary to select xfs_growfs with the mountpoint path eg.
```
							xfs_growfs /home
						
```

For VPS servers with WebApps , the disk partition is automatically modified after the VPS plan upgrade.
