The original partition / data of the Linux system has data, so reinstall the system without formatting / data partition

Need to prepare a virtual machine with / data partition

Then load ISO to start reloading and keep the / data partition

Load directly into the partition interface

Know from the beginning that the / data partition is 2048MB, so choose to keep this partition directly.

Then delete the other partitions and then re-partition

Then wait for the system to be reinstalled as usual.

After the system is reinstalled, check the / data partition file and prove that it has been successful.

Add a disk to the system and use LVM management to expand the existing volume group

Enter the system and view the partition df-h

You can see the two partitions using LVM when installing the system: /, / var

View volume group name and volume group usage vgdisplay

View the space status of the current logical volume, as shown in the following figure:

. Now I feel that / var 8G is not enough. I want to expand it to 28G.

Insert a new 20g hard drive; view it with 'fdisk-1'

Format partition operation 'fsdisk / dev/sdb'

Set the newly added disk to LVM mode

Confirm the partition

Create the newly added partition / dev/sdb1 as a physical volume

Expand the volume group centos. Extend physical volume / dev/sdb1 to centos

At this time, centos has 20g of free space, so extend / dev/sdb1 to / var.

At this time, although the 20g disk has been extended to / var but not written to the file system, enter / etc/fstab to confirm

Write to the file system to make its expansion effective
