6.2 newfs/tunefs minfree
On 6.2-STABLE, newfs(8) manpage reports: -o optimization [..snip..] If the value of min-free (see above) is less than 8%, the default is to optimize for space; if the value of minfree is greater than or equal to 8%, the default is to optimize for time. However, tunefs(8) manpage reports: -m minfree Specify the percentage of space held back from normal users; the minimum free space threshold. The default value used is 8%. Note that lowering the threshold can adversely affect performance: o Settings of 5% and less force space optimization to always be used which will greatly increase the overhead for file writes. Am I correct in assuming therefore that if min-free is set to less than 8% but optimization is set to time, the time method will still be used until the free space on the fs reaches 5% at which point it will force the 'space' method to be used? Or, is this a mixup in the documentation? Or, am I just reading it wrong? Regards, Richard smime.p7s Description: S/MIME Cryptographic Signature
