Olá pessoal, adicionei um novo HDD ao meu servidor SSD existente. Configuração como abaixo:
Servidor: CentOS release 6.9 (Final)
Filesystem Size Used Avail Use% Mounted on
/dev/md2 204G 179G 15G 93% /
tmpfs 16G 0 16G 0% /dev/shm

Novo disco:
Disk /dev/sdc: 512.1 GB
Mas ainda tenho problema aumentando /dev/md2 .

O que eu quero é estender a partição raiz atual com o novo espaço no novo disco rígido.
Eu adicionei o novo HDD para invadir a partição /dev/sdc1 mas Array Size não mudou.
