Eu tenho um host que roda CentOS-6 com Linux 2.6.32-696.18.7.el6.x86_64 (sim, bem antigo) e fiquei sem espaço em disco no sistema de arquivos raiz.
O tamanho do sistema de arquivos é 16G, dumostra cerca de 3G sendo usado pelos arquivos. Claro, eu corri lsof +L1, encontrei processos que continham os grandes arquivos de log que haviam sido desvinculados antes (sim, havia alguns desses processos, então eu os matei), mas o sistema de arquivos ainda está cheio e qualquer coisa pode gravar nele ( não, inodes estão bem, não há disponíveisblocos).
lsof +L1ainda mostra alguns arquivos, mas esses arquivos não ocupam muito tamanho, então tenho certeza que posso ignorar isso:

O que mais devo tentar fazer (tenho certeza de que a reinicialização ajudará, mas gostaria de evitar fazer isso)?
Obrigado!
