Usei o Gparted Live cd para redimensionar um grupo de volumes e uma partição lógica quando reinicio e tento usar, lvextend –l +100%FREE /dev/vda5recebo esta mensagem:

Run `lvextend --help' for more information.

Ao trabalhar com 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 possui um PV(Volume Físico) e um VG(Grupo de Volumes), é mais fácil estender o grupo de volumes adicionando dispositivos adicionais.
Para estender o grupo de volumes, por exemplo, vg1você pode fazer o seguinte:
vgextend vg1 /dev/vda5
Depois de estender o grupo de volumes, precisamos redimensionar nosso LV(Volume Lógico)
Para estender o LVvocê 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 resize2fsseguido do caminho para o arquivo LV. Por exemplo:
resize2fs /dev/vg1/your_lv
Obs: lvextendpossui a -rflag que chama resize2fsem background e faz essa operação automaticamente.
Para resumir o acima:
- Estenda 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:
- Reduza o sistema de arquivos
- Reduza o tamanho do volume lógico
- Remova o dispositivo, por exemplo,
/dev/vda5do grupo de volumes
