Related question about block sizes, but there are many many other options when creating an ext3 filesystem.

I think the other question has an answer with great advice of block size, that it general it is good if block size is the same size as CPU page size. But what about all the other options?

Best practice is to stick with the defaults. Only exceptions are filesystems where one knows that the files stored will be all very small or the other way around: All files will be very large. In both of these cases it may be worth to adjust the block size.

Advantage of sticking with defaults is that you don't have an uncommon setup and you will not be the beta-tester for exotic combinations.

  • I agree. Stick with the defaults until you know and understand the options well enough that you don't need to ask.

  • So you advocate the "gain knowledge without asking questions" type of learning. Got it. ;-) Oct 26 '11 at 15:30
  • I knew someone would say "stick to the defaults", so +1 for that. Oct 26 '11 at 15:32
  • @AmigableClarkKant, you got this answer partly because of how you asked the question. Instead of asking about 'best practices', you should be asking under what circumstances is tweaking a certain value appropriate.

  • I just realized that! :-/ Accepting answer. Thanks for pointing it out. Best practices IS actually to not change anything unless you know why. Oct 26 '11 at 17:07
