You can tune the free space and set it to 1% or so, but if you write
to the partition a lot and it fills up, it will get a) very slow
to write to and b) fragmented, so very slow to read from as well.
For a filesystem with static content (like /usr) that you fill up
only once and then just read from it doesn't matter as much.
I don't know enough about ext3 to tell if this is codswallop. It sounds reasonable...https://listman.redhat.com/archives/ext3-users/2002-February/msg00026.html wrote:Ummm, the 5% reservation is to prevent the high levels of
