Eu tenho esse problema com meu RHEL 7.1 virtualizado.
Eu criei esta VM com disco com provisionamento thin. Eu pensei que eu sei como deveria funcionar - o espaço provisionado estaria disponível para a VM, mas, desde que não seja realmente usado, ele não será bloqueado no armazenamento.
Mas quando estou trabalhando com VM, realmente não tenho espaço disponível. Preciso de mais espaço no meu diretório / root. Há alguma saída do terminal:
[root@rheldemo ~]# df -h
