It makes sense to add additional slots upfront to allow you to grow later.
It will be easier if you have slots available. So go with 4 atleast if not 6.
The only downside is that it will reserve more journal space. But it's space
you can get it back later.

Also enable most features. The list depends on the version of the tools/fs you
have. If you are on a kernel that is based off 2.6.32+, then you should
be able to enable most features. For more, refer to man mkfs.ocfs2.
