Eu usei o Gparted Live cd para redimensionar um grupo de volumes e uma partição lógica quando reiniciei e tentei usar o lvextend –l +100%FREE /dev/vda5 i para receber esta mensagem:

  Path required for Logical Volume "–l"
  Please provide a volume group name
  Run 'lvextend --help' for more information.

Aqui está minha pvs , lvs , vgs output:

e aqui está df -h output

Eu tentei este comando

  lvextend –l +100%FREE /dev/vda5
  lvextend –l +100%FREE d8dev-vg
  lvextend –l +100%FREE /dev/root

Mas todos os mesmos resultados

  Please provide a volume group name

EDITAR: eu fiz lvextend /dev/dm-0 /dev/vda5 agora minha lvs saída é:

  root   d8dev-vg -wi-ao---    8.76g

Mas /dev/dm-0 ainda é baixo:

Ao trabalhar com o LVM (Logical Volume Manager), você deve ter em mente que a ordem de operação é imperativa. Se você não seguir a ordem, corre o risco de perder seus dados.

Se você já tem um PV (Volume Físico) e um VG (Grupo de Volume), é mais fácil estender o grupo de volumes adicionando dispositivos adicionais.

Para estender o grupo de volume, por exemplo, vg1 , você pode fazer o seguinte:

vgextend vg1 /dev/vda5

Depois de estender o grupo de volumes, precisamos redimensionar nosso LV (Volume lógico)

Para estender o LV , você pode usar o seguinte

lvextend /dev/vg1/your_lv /dev/vda5

Neste estágio, apenas o volume lógico foi estendido, mas não o sistema de arquivos.

Para estender o sistema de arquivos, você pode usar resize2fs seguido pelo caminho para o LV . Por exemplo:

resize2fs /dev/vg1/your_lv

Observação: lvextend tem o sinalizador -r , que chama resize2fs em segundo plano e faz essa operação automaticamente.

Para resumir o acima:

Estender o grupo de volumes
Estenda o volume lógico
Redimensionar o sistema de arquivos

Para reduzir um sistema de arquivos (não é possível com xfs ), siga o seguinte procedimento:

Diminuir o sistema de arquivos
Reduza o tamanho do volume lógico
Remova o dispositivo, por exemplo, /dev/vda5 do grupo de volume
