Здрасвствуйте, вроде бы детская проблема, а решить не могу. Помогите.

cat /etc/mtab| grep ftp
/dev/mapper/r10storage-lvol0 /var/ftp ext3 rw,nosuid,nodev,relatime 0 0

Пытаюсь отмонтировать раздел:
sudo umount /dev/mapper/r10storage-lvol0
umount: /var/ftp: device is busy.
         (In some cases useful info about processes that use
          the device is found by lsof(8) or fuser(1))

sudo fuser -vm /var/ftp - в выводе пусто
sudo lsof | grep ftp - тоже пусто

/var/ftp был расшарен по nfs, но теперь nfs остановлен.

Что ещё можно посмотреть, что бы понять чем занят раздел?
