Estou tentando adicionar espaço à minha partição raiz e realmente não tenho certeza da maneira mais segura de fazer isso. Eu li este tópico, Posso redimensionar a partição raiz sem desinstalar e reinstalar o Linux (ou perder dados)? , mas não acho que as informações estejam alinhadas com o meu sistema.
Qualquer ajuda seria apreciada pelo usuário. Além disso, naquele post, F1234K pediu recomendações sobre boa leitura para aprender essas coisas, mas ninguém respondeu a elas. Eu também estaria muito interessado em algum material didático sobre o assunto.
Obrigado!
edit: Devo acrescentar que meu objetivo é pegar 20 GB de sdb6 e colocá-lo em sdb1. sdb6 é um volume lógico de sdb2.
