Para adicionar um disco maior que 2TB no Ubuntu precisamos utilizar o parted<\/em>, pois o fdisk<\/em> n\u00e3o reconhece parti\u00e7\u00f5es acima de 2TB.<\/p>\n

Primeiramente, ap\u00f3s a atualiza\u00e7\u00e3o dos reposit\u00f3rios (sempre atualize antes de iniciar a instala\u00e7\u00e3o de qualquer programa) executamos:<\/p>\n

apt-get install parted\r\n<\/pre>\n
Identificando o seu Disco R\u00edgido (Hard Disk)<\/h3>\n
Geralmente ele est\u00e1 nas parti\u00e7\u00f5es sda<\/strong>, sdb<\/strong>, sdc<\/strong>…sdx.\u00a0<\/strong>Para identificar o local correto execute:<\/p>\n
fdisk -l\r\n\r\nou\r\n\r\nlsblk<\/span><\/pre>\n
Ap\u00f3s identificado, execute o seguinte comando:<\/p>\n
fdisk <\/span>–<\/span>l <\/span>\/<\/span>dev<\/span>\/<<\/span>seu disco aqui<\/span>><\/span><\/div>\n
No nosso exemplo ser\u00e1:<\/p>\n
fdisk <\/span>-<\/span>l <\/span>\/<\/span>dev<\/span>\/<\/span>sdb<\/span><\/pre>\n
Voc\u00ea ver\u00e1 as seguintes informa\u00e7\u00f5es:<\/p>\n
Disk<\/span> \/<\/span>dev<\/span>\/<\/span>sdb<\/span>:<\/span> 4000.8<\/span> GB<\/span>,<\/span> 4000787030016<\/span> bytes\r\n<\/span>255<\/span> heads<\/span>,<\/span> 63<\/span> sectors<\/span>\/<\/span>track<\/span>,<\/span> 486401<\/span> cylinders\r\n<\/span>Units<\/span> =<\/span> cylinders of <\/span>16065<\/span> *<\/span> 512<\/span> =<\/span> 8225280<\/span> bytes\r\n<\/span>Sector<\/span> size <\/span>(<\/span>logical<\/span>\/<\/span>physical<\/span>):<\/span> 512<\/span> bytes <\/span>\/<\/span> 4096<\/span> bytes\r\nI<\/span>\/<\/span>O size <\/span>(<\/span>minimum<\/span>\/<\/span>optimal<\/span>):<\/span> 4096<\/span> bytes <\/span>\/<\/span> 4096<\/span> bytes\r\n<\/span>Disk<\/span> identifier<\/span>:<\/span> 0x00000000<\/span>\r\nDisk<\/span> \/<\/span>dev<\/span>\/<\/span>sdb doesn<\/span>'t contain a valid partition table<\/span><\/pre>\n
Anote o tamanho correto do disco, no nosso caso 4000.8 GB, ele ser\u00e1 usado mais para a frente.<\/p>\n
Criando a parti\u00e7\u00e3o.<\/h3>\n
Para adicionarmos uma nova parti\u00e7\u00e3o utilizando o parted\u00a0<\/em>seguiremos esses passos:<\/p>\n
parted <\/span>\/<\/span>dev<\/span>\/<<\/span>seu disco aqui<\/span>><\/span><\/pre>\n
Novamente no nosso exemplo ficaria:<\/p>\n
parted <\/span>\/<\/span>dev<\/span>\/<\/span>sdb<\/span><\/pre>\n
Voc\u00ea ver\u00e1 a sa\u00edda a seguir:<\/p>\n
GNU <\/span>Parted<\/span> 2.3<\/span>\r\nUsing<\/span> \/<\/span>dev<\/span>\/<\/span>sdb\r\n<\/span>Welcome<\/span> to GNU <\/span>Parted<\/span>!<\/span> Type<\/span> 'help'<\/span> to view a list of commands<\/span>.<\/span>\r\n(<\/span>parted<\/span>)<\/span><\/pre>\n
1 – Criando uma parti\u00e7\u00e3o GPT<\/h4>\n
Adicione o tipo de parti\u00e7\u00e3o que iremos criar:<\/p>\n
mklabel gpt<\/span><\/pre>\n
Caso n\u00e3o seja um disco novo, ou j\u00e1 contenha uma parti\u00e7\u00e3o anterior, o programa ir\u00e1 te avisar, responda y<\/strong><\/p>\n
Warning<\/span>:<\/span> The<\/span> existing disk label on <\/span>\/<\/span>dev<\/span>\/<\/span>sdb will be destroyed <\/span>and<\/span> all data on <\/span>this<\/span> disk will be lost<\/span>.<\/span> Do<\/span> you want to <\/span>continue<\/span>?<\/span>\r\nYes<\/span>\/<\/span>No<\/span>?<\/span> yes\r\n<\/span>(<\/span>parted<\/span>)<\/span><\/pre>\n
2 – Definindo a unidade que utilizaremos<\/h4>\n
Definido a unidade de medida, no nosso caso GB<\/p>\n
unit GB<\/span><\/pre>\n
3 – Criando a parti\u00e7\u00e3o<\/h4>\n
Vamos adicionar uma parti\u00e7\u00e3o prim\u00e1ria.<\/p>\n
mkpart primary <\/span><<\/span>from<\/span> GB<\/span>><\/span> <<\/span>to GB<\/span>><\/span><\/pre>\n
No meu caso, vou utilizar todo o disco para a nova parti\u00e7\u00e3o:<\/p>\n
mkpart primary <\/span>0.0GB<\/span> 4000.8GB<\/span><\/pre>\n
4 – Verificando se a parti\u00e7\u00e3o foi criada<\/h4>\n
Para visualizarmos a parti\u00e7\u00e3o criada:<\/p>\n
print<\/span><\/pre>\n
Sua saida ser\u00e1 algo parecido com:<\/p>\n
Model<\/span>:<\/span> ATA WDC WD40EFRX<\/span>-<\/span>68W<\/span> (<\/span>scsi<\/span>)<\/span>\r\nDisk<\/span> \/<\/span>dev<\/span>\/<\/span>sdb<\/span>:<\/span> 4001GB<\/span>\r\nSector<\/span> size <\/span>(<\/span>logical<\/span>\/<\/span>physical<\/span>):<\/span> 512B<\/span>\/<\/span>4096B<\/span>\r\nPartition<\/span> Table<\/span>:<\/span> gpt\r\n\r\n<\/span>Number<\/span>  Start<\/span>   End<\/span>     Size<\/span>    File<\/span> system  <\/span>Name<\/span>     Flags<\/span>\r\n 1<\/span>      0.00GB<\/span>  4001GB<\/span>  4001GB<\/span>  ext4         primary<\/span><\/pre>\n
Estando tudo correto, podemos sair do programa parted<\/em>:<\/p>\n
quit<\/span><\/pre>\n
Criando o sistema de arquivos (filesystems)<\/h2>\n
No meu caso, eu irei utilizar o sistema de arquivo do tipo ext4<\/em>, para isso executaremos:<\/p>\n
mkfs<\/span>.<\/span>ext4 <\/span>\/<\/span>dev<\/span>\/<<\/span>sua parti\u00e7\u00e3o criada<\/span>><\/span><\/pre>\n
No meu exemplo:<\/p>\n
mkfs<\/span>.<\/span>ext4 <\/span>\/<\/span>dev<\/span>\/<\/span>sdb1<\/span><\/pre>\n
Espere a finaliza\u00e7\u00e3o do comando. No meu caso demorou cerca de 20 minutos:<\/p>\n
mkfs<\/span>.<\/span>ext4 <\/span>\/<\/span>dev<\/span>\/<\/span>sdb1\r\nmke2fs <\/span>1.41<\/span>.<\/span>12<\/span> (<\/span>17<\/span>-<\/span>May<\/span>-<\/span>2010<\/span>)<\/span>\r\nFilesystem<\/span> label<\/span>=<\/span>\r\nOS type<\/span>:<\/span> Linux<\/span>\r\nBlock<\/span> size<\/span>=<\/span>4096<\/span> (<\/span>log<\/span>=<\/span>2<\/span>)<\/span>\r\nFragment<\/span> size<\/span>=<\/span>4096<\/span> (<\/span>log<\/span>=<\/span>2<\/span>)<\/span>\r\nStride<\/span>=<\/span>0<\/span> blocks<\/span>,<\/span> Stripe<\/span> width<\/span>=<\/span>0<\/span> blocks\r\n<\/span>183148544<\/span> inodes<\/span>,<\/span> 732566272<\/span> blocks\r\n<\/span>36628313<\/span> blocks <\/span>(<\/span>5.00<\/span>%)<\/span> reserved <\/span>for<\/span> the <\/span>super<\/span> user\r\n<\/span>First<\/span> data block<\/span>=<\/span>0<\/span>\r\nMaximum<\/span> filesystem blocks<\/span>=<\/span>4294967296<\/span>\r\n22357<\/span> block groups\r\n<\/span>32768<\/span> blocks per <\/span>group<\/span>,<\/span> 32768<\/span> fragments per <\/span>group<\/span>\r\n8192<\/span> inodes per <\/span>group<\/span>\r\nSuperblock<\/span> backups stored on blocks<\/span>:<\/span>\r\n\t32768<\/span>,<\/span> 98304<\/span>,<\/span> 163840<\/span>,<\/span> 229376<\/span>,<\/span> 294912<\/span>,<\/span> 819200<\/span>,<\/span> 884736<\/span>,<\/span> 1605632<\/span>,<\/span> 2654208<\/span>,<\/span>\r\n\t4096000<\/span>,<\/span> 7962624<\/span>,<\/span> 11239424<\/span>,<\/span> 20480000<\/span>,<\/span> 23887872<\/span>,<\/span> 71663616<\/span>,<\/span> 78675968<\/span>,<\/span>\r\n\t102400000<\/span>,<\/span> 214990848<\/span>,<\/span> 512000000<\/span>,<\/span> 550731776<\/span>,<\/span> 644972544<\/span>\r\nWriting<\/span> inode tables<\/span>:<\/span> done<\/span>\r\nCreating<\/span> journal <\/span>(<\/span>32768<\/span> blocks<\/span>):<\/span> done<\/span>\r\nWriting<\/span> superblocks <\/span>and<\/span> filesystem accounting information<\/span>:<\/span> done<\/span>\r\nThis<\/span> filesystem will be automatically <\/span>checked<\/span> every <\/span>31<\/span> mounts <\/span>or<\/span>\r\n180<\/span> days<\/span>,<\/span> whichever comes first<\/span>.<\/span>  Use<\/span> tune2fs <\/span>-<\/span>c <\/span>or<\/span> -<\/span>i to <\/span>override<\/span>.<\/span><\/pre>\n
Adicionando a parti\u00e7\u00e3o ao fstab<\/h2>\n
Essa parte \u00e9 a mais tranquila, e n\u00e3o existe segredo quanto a inclus\u00e3o da parti\u00e7\u00e3o nova. No meu exemplo vou usar o diret\u00f3rio\u00a0\/dados:<\/p>\n
mkdir <\/span>\/dados<\/span><\/pre>\n
Abra o arquivo \/etc\/fstab<\/em>\u00a0e adicione a seguinte linha:<\/p>\n
\/dev\/<\/span><<\/span>sua parti\u00e7\u00e3o<\/span>><\/span>  \/diret\u00f3rio<\/span>   <<\/span>sistema de arquivos<\/span>><\/span>    defaults        <\/span>0<\/span> 0<\/span><\/pre>\n
No meu exemplo ficou:<\/p>\n
\/dev\/<\/span>sdb1    <\/span>\/dados<\/span>            ext4    defaults        <\/span>0<\/span> 0<\/span><\/pre>\n
Testando as configura\u00e7\u00f5es<\/h4>\n
Para testar se esta tudo ok, eu primeiramente realizo o seguinte comando<\/p>\n
mount \/dev\/sdb1 \/dados<\/span><\/pre>\n
Caso eu n\u00e3o encontre nenhum erro, eu realizo a montagem utilizando o default, para verificar se n\u00e3o ter\u00e1 erro ao reiniciar o servidor por exemplo.<\/p>\n
mountall<\/span><\/pre>\n
Se n\u00e3o houve erro, sua parti\u00e7\u00e3o est\u00e1 formatada, montada e quando reiniciar o servidor ela ser\u00e1 montada automaticamente.<\/p>\n","protected":false},"excerpt":{"rendered":"
