But the currently "known method" is to use gnop(8). Here's an
example:

Now, that's for ZFS, but I'm under the impression the exact same is
needed for FFS/UFS.
Info: gnop will not work for FFS/UFS because gnop is a temporary
solution (needs to be done by hand at each reboot). For FFS/UFS you
need to align the slice/partition and chose a good blocksize/fragsize
combination (e.g. 32k/4k).
Thanks, Alexander.
This is what I had expected after reading the man pages, though I
would think -b 65560 -f 8192' would be a bit more reasonable in this
day of bloated file formats. it's been years since I have hit a
problem with lack of inodes.
I suggest to test this somewhere first. I have no evidence that it can
not work, but the blocksize/fragsize settings where subject to some
unexpected results in the past when they where changed to a bad
combination. IIRC this should be fixed now, but my memory may cheat on
me...
Bye,
Alexander.
