RE: Filesystem Block Size ? 1K or 4K or 8K ?

One of the reasons that ASM was offered originally was to provide striping and mirroring to shops that didn't already have a high-end storage system (such as Symmetrix) in place. If you have moderately-sized systems and just buy a bunch of disks, using ASM to manage them is probably a good idea. But if you've already paid big bucks for Symmetrix, ASM just doesn't give you that much in return for the additional complexity, learning curve, and risk.

If you would, please share with us your reasons to avoid ASM. Based on your response, I'm guessing that the reasons might include "because that's the way I've always done it".
Personally, I don't use it as it adds more complexity to our environment.
We (by which I really me 'I') don't need to add any more complexity.
- Additional instance for ASM
- file management is simpler
- storage admins have easy direct access to see what's on disk.
I'm sure there are some rebuttals to this.
Let's hear 'em!
