Accept it :-) Or change the minimum free space on the drive. Here's the relevant part of the tunefs manpage: -m minfree Specify the percentage of space held back from normal users; the minimum free space threshold. The default value used is 8%. This value can be set to zero, however up to a factor of three in throughput will be lost over the performance obtained at a 10% threshold. Settings of 5% and less force space optimization to always be used which will greatly increase the overhead for file writes. Note that if the value is raised above the current usage level, users will be unable to allocate files until enough files have been deleted to get under the higher threshold. I haven't checked, but I suspect the FAQ and Handbook at www.freebsd.org have more information on this... -philip
