Estos son registros que pertenecen a un contenedor eliminado. Una forma de cerrarlos es reiniciando el daemon de docker. Esto no siempre es factible.
Otra forma de liberar este espacio es encontrar el descriptor de archivo relevante y truncarlo:
ls -lh /proc/17511/fd/ | grep e49d81fclr-x------ 1 root root 64 Sep 8 08:06 25 -> /var/lib/docker/containers/39ba30ffc0e218ee830576570222284a93ebb458eadf46933d2dd7afe49d81fc/39ba30ffc0e218ee830576570222284a93ebb458eadf46933d2dd7afe49d81fc-json.log (deleted)
Donde 17511
es el pid de docker y e49d81fc
es parte del nombre de archivo de registro / id de contenedor infractor. Aquí, el fd es /proc/17511/fd/25, así que truncar:
cat /dev/null > /proc/17511/fd/25
