Sorry for my laziness, I just had a read at the mkfs.ocfs2 man page and
had answered to some questions by myself.
If you can still give me some hints about the block-size and
cluster-size values about the filesystem that I'm going to create, I'd
appreciated it. Also, I'm a little bit curious
If you are dealing with creating/removing lots of small files, a large
journal
will help. Currently there is no way other than trial and error. We'll look
into making this easier but right now there is no other way.
Pick the largest value of all the subcomponents for the hb timeout.
