Increasing disk space in CentOS 7

After increasing the disk in the control panel, you need to make available to the operating system:

Open a terminal (see connection instructions ) as root and enter the following commands:
[root@CentOSx64 ~]# echo 1 > /sys/block/sda/device/rescan

Run fdisk:

[root@CentOSx64 ~]# fdisk //sda

Next, run the commands in the fdisk utility interface.

Delete the /dev/sda2 partition:

Command ( for help): dPartition number (1,2, default 2): 2

Create a section:

Command (m for help): n

Select partition type – primary (p)

Select (default p): pPartition number (2-4, default 2): 2

We accept the default values ​​\u200b\u200b- press Enter twice:

First sector (XXX-YYY, default ZZZ):
Last sector, +sectors or +size{K,M,G} (XXX-YYY, default ZZZ):

Change partition type

Command (m for help): t
Partition number (1-2): 2
Hex (type L to list all codes): 8e
Command (m for help): w

We inform the kernel about the changes: Change the[root@CentOSx64 ~]# partx -u /dev/sda2physical volume:[root@CentOSx64 ~]# pvresize /dev/sda2Find out the name of the logical volumelvdisplay
