Partição acusando espaço - LVM /var

Olá pessoal!

Estou com uma duvida relacionada a partições.
Uso o Zabbix aqui na empresa e recentemente apareceu um alerta sobre o /var do servidor, onde a mesma estaria com menos de 5% do espaço.
A partição é do tipo LVM, onde em sistema me mostra que tem 137G.
Acessando o /var, verifiquei que ela possui apenas 25G, porem usando o comando "df -h" me mostra o seguinte:

Filesystem Size Used Avail Use% Mounted on
/dev/mapper/system-var 135G 126G 3.9G 98% /var

Segue informações do sistema:

Alguem tem alguma ideia do que pode estar ocupando os outros 100G do /var?

Esqueci de postar o retorno desse comando.
