[aklug] File system thoughts

Hash: SHA1

Just a thought I was pondering as I worked on my Operating Systems homework:

We've all heard people say what their preferred file systems are. When
we want help deciding for ourselves, the first thing we look for is
those nice performance studies online, where multiple file systems are
made to perform the same set of activities, and the speed results are
lined up next to each other in order to determine strengths and weaknesses.

But the only thing I never see discussed in these studies is the matter
of adjustable file-system options -- allocation options in particular.
For example, if you read through MKFS.XFS(8) you can see options for
setting block size, inode size, allocation group count, et cetera et cetera.

I'm no file systems expert, but it seems to me like it is one thing to
judge a file system with default settings, but another matter altogether
to see how it does after you've tuned it to your needs. One thing I'd
like to do in future system installs is to learn more about the file
system and to see how the can be manipulated in favor of the purpose of
the partition.
