Vendo isso me lembrei que ja aconteceu comigo a um bom tempo atraz , uns
3 anos , que um servidor bootava do nada e foi resolvido dando boot
single o rodando duas (2) vezes fsck -y , era uma inconsistencia de
filesystem, ja vi tb um arquivo de log corrompido que dizia ter 20Gb
quanto tinhas apenas alguns kb , a solução foi remover ele e criar um
novo com touch , ou ainda /dev/null > nomedoaquivocomrrompido , de uma
examinada nos seus arquivos de log, a causa foi uma queda de energia bem
qdo o dito cujo estava sendo gravado.

Se isso não for suficiente MOVA os arquivos de log e bin do
mysql,mysql-bin.000001 .... , inclusive o index do mysql,
mysql-bin.index , para um diretorio de backup, não os delete pois pode
precisar deles para restaurar o seu banco caso não tenha um backup
atualizado, cuidada para NÂO remover arquivos ib* que são as tabelas
