Esta é a maneira que parece ao estender o lv, mas não o sistema de arquivos sobre ele. O próximo passo depois de ter o tamanho que você quer no lv é aumentar o sistema de arquivos lá. Isso pode ser feito com resize2fs /dev/sdrive/shared .
Existe um servidor pelo qual sou responsável que mostra uma unidade (cheia) e muito menor do que a unidade deveria ser. Meu conhecimento de LVM não é profundo o suficiente para ver o porquê. Eu poderia usar alguma ajuda de um bom conjunto de olhos frescos porque eu estive coçando (e batendo) minha cabeça nisso.
Eu tenho um Volume Lógico / dev / sdrive / shared que é de 352 GB. Meu sistema operacional, Ubuntu 14.04.01 , parece pensar apenas que /dev/mapper/sdrive-shared é de 126 GB. Eu não sei o que eu estraguei ou fiz de errado para causar isso ou como corrigi-lo. Abaixo eu estou incluindo a saída de quais comandos eu conheço para investigar o problema. Eu não vejo de onde vem os 126GB.
Algumas coisas parecem erros para mim (como fdisk reclamando sobre uma tabela de partição, mas parted mostrando bem), mas procurar alguns fóruns dizem que este é o comportamento esperado quando se trata de LVM. Mais uma vez, meu conhecimento é muito fraco para diagnosticar e estou me agarrando a palhas e apreciando qualquer ajuda.
