Nesse artigo ser\u00e1 abordado como instalar um novo HD SATA no CentOS 5.6 e 6. O processo segue os seguintes passos: reconhecimento do HD, cria\u00e7\u00e3o e formata\u00e7\u00e3o da parti\u00e7\u00e3o, cria\u00e7\u00e3o do ponto de montagem, montagem da parti\u00e7\u00e3o e para finalizar montagem autom\u00e1tica da parti\u00e7\u00e3o.<\/p>\n
Antes de prosseguir, \u00e9 interessante ler o seguinte artigo: <\/p>\n
Nosso objetivo est\u00e1 contextualizado da seguinte forma:<\/p>\n
O primeiro passo \u00e9 verificar se o CentOS reconheceu os novos HDs.<\/p>\n
Utilize o fdisk para isso:<\/p>\n
\r\n[root@ ~]# fdisk -l\r\n \r\nDisk \/dev\/sda: 107.3 GB, 107374182400 bytes\r\n255 heads, 63 sectors\/track, 13054 cylinders\r\nUnits = cylinders of 16065 * 512 = 8225280 bytes\r\n \r\n Device Boot Start End Blocks Id System\r\n\/dev\/sda1 * 1 13 104391 83 Linux\r\n\/dev\/sda2 14 13054 104751832+ 8e Linux LVM\r\n \r\nDisk \/dev\/sdb: 137.4 GB, 137438953472 bytes\r\n255 heads, 63 sectors\/track, 16709 cylinders\r\nUnits = cylinders of 16065 * 512 = 8225280 bytes\r\n \r\nDisk \/dev\/sdb doesn't contain a valid partition table\r\n \r\nDisk \/dev\/sdc: 137.4 GB, 137438953472 bytes\r\n255 heads, 63 sectors\/track, 16709 cylinders\r\nUnits = cylinders of 16065 * 512 = 8225280 bytes\r\n \r\nDisk \/dev\/sdc doesn't contain a valid partition table\r\n<\/pre>\nAnalisando o resultado, podemos ver que os 2 HDs foram reconhecidos com sucesso. O hd1 foi reconhecido como \/dev\/sdb e o hd2 como \/dev\/sdc. Outra informa\u00e7\u00e3o que pode ser vista \u00e9 que ainda n\u00e3o foram particionados.
\nCriando a parti\u00e7\u00e3o<\/p>\nA cria\u00e7\u00e3o da parti\u00e7\u00e3o tamb\u00e9m \u00e9 feita pelo fdisk, repare que o fdisk \u00e9 uma ferramenta interativa, dentro dele ser\u00e1 utilizado os comando n e w.<\/p>\n
\r\n[root@ ~]# fdisk \/dev\/sdb \r\nDevice contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel\r\nBuilding a new DOS disklabel.

Com a parti\u00e7\u00e3o criada, \u00e9 hora de formatar.<\/p>\n
Para formatar utilize o mkfs.ext4:<\/p>\n

Para criar o ponto de montagem:<\/p>\n

\nConfigurando a montagem autom\u00e1tica<\/p>\nAgora vamos automatizar a montagem, n\u00e3o queremos montar essa parti\u00e7\u00e3o toda vez que iniciarmos o CentOS. Para isso temos que editar o \/etc\/fstab: <\/p>\n
