OVL CentOS 6. Как увеличить размер диска?

Question

[iPingvo]

Друзья.
Есть сервер на OVL.com с CentOS 6.7, места куплено было 20 Гб и нехватило под задачи, докупили еще 20 Гб места, но в листинге разделов оно никак не фигурирует.
Как прибить приобретенное место к имеющемуся (желательно без потери данных).

[root@vps251121 mail]# fdisk -l

Оповещение Linux о том, что размер жесткого диска изменился
Для этого необходимо знать SCSI ID устройства. Его можно посмотреть в логе загрузки dmesg, например вот в в таком сообщении:

sd 2:0:0:0: [sda] 209715200 512-byte logical blocks: (107 GB/100 GiB)

Соответственно ID нашего устройства — 2:0:0:0.

Выполняем следующую команду:

# echo 1 > /sys/bus/scsi/devices/2\:0\:0\:0/rescan

Обратите внимание на написание ID.
После выполнения команды убеждаемся, что размер диска изменился — в логе должно появиться сообщение:

May 22 01:49:58 windycat kernel: sda: detected capacity change from 107374182400 to 128849018880
