This is the result: # /root/bin/fstat -m -v -f /usr USER CMD PID FD MOUNT INUM MODE SZ|DV R/W # _ It shows NOTHING. I have made a copy of fstat binary in /root/bin, which is possible because all needed libs are in /. Furthermore, I've carefully studied the output of "ps ax" and even of "top -t", but as well, nothing that indicates some activity on /usr... > You have a mount on top of /usr, ie.: /usr/local or /usr/ports. No. From /etc/fstab: # Device Mountpoint FStype Options Dump Pass# # ----------- --------------------- ------ ------------- ----- ----- /dev/ad0s1b none swap sw 0 0 /dev/ad0s1a / ufs rw 1 1 /dev/ad0s1d /tmp ufs rw 2 2 /dev/ad0s1e /var ufs rw 2 2 /dev/ad0s1f /usr ufs rw 2 2 /dev/ad0s1g /export/home ufs rw 2 2 These are the only partitions on ad0. /usr has its own partition, nothing mounted "on top" of it. (You mentioned a valid point: I sometimes have another disk mounted inside /export/home, and I cannot umount /export/home while this partition is mounted. But that's not the case here.) This is REALLY strange, I should get a whiteboard, some pens and start making a drawing of the symptoms, until Dr. Cuddy tells me not to do so. :-) -- Polytropon >From Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
