Hi, on my Debian system the RAID discs are partitioned like that: /dev/md1 9.2G 8.2G 593M 94% / tmpfs 252M 16K 252M 1% /dev/shm /dev/md3 37G 33G 2.5G 94% /usr /dev/md0 92M 31M 57M 36% /boot ... How can I determine where the 8.2G of /dev/md1 are used (and excluding the other partitions)? When I use "du" on "/" it will also take "/usr" from /dev/md3 and other mounted directories into account. Regards, Chris
