I know the tunefs man page contains warnings about lowering the
minfree threshold on a disk to below 5%, but besides file write
performance, is there any other reason *not* to drop it down to 1 or
2 percent?
The specific application is with FTP filesystems. I have a couple
of 4GB disks for our mirror archives and I wouldn't mind recovering
the 300MB or so on each drive. Yeah, disk is cheap, but it still
seems like a waste to me.
Since the only writes occuring on those drives come from the
mirror process, I figure network performance will always be the
bottleneck rather than disk writes.
