Hello! Look at this: /dev/da0s1f 104164493 104061031 -8229697 109% /usr but du -k -d1 /usr gives a lot less (about 20GB). My guess is that something has mmap-ed a HUGE chunk of disk space. If I reboot the space is freed. The question is how can i sees what process mmaped how much space and where? -- Regards, Artem
