I've seen people discuss about this and it happened to me as well. Freebsd 8.1 stable 25th september amd64 This server has one single boot disk with ufs + 1 array (hardware, 3ware) which hold 2,7TB data. I've formatted the latter with ZFS. Things seemed to work ok until I upgraded the system. One day the server jails didn't boot anymore. I checked and the array occupation was 100% with 0 byte free. This sounded strange, so I found a hidden file under /var/amavis/.spamassassin. I removed the dir, started again, but after a while it grew again until the system became unusable. This is how I solved: I moved the amavis partition under UFS, then mounted with nullfs that dir under /var in the zfs jail. I solved in the sense that it didn't grow anymore, but the fs occupation stayed very near 100%, with only 1GB free space. If I launch du -s under /zfs (host machine, not jail) I get a total space of about 750GB, but df -h always turns up with 2,7TB space occupied. I tried a zpool upgrade zfs and zpool scrub zfs, but to no avail. What should I do. short of moving the data, destroying the pool and creating it again (which I can't very easily do)? Thanks.
