[Linux-cluster] configuring GFS2

So, in short, I'm blow away by the sheer amount of information out there in regards to the RH cluster project.  So much, that I find it hard to find particular information.  I'm hoping that I can have a few things explained that I'm having trouble finding information for.

1.  What -exactly- is the process necessary for setting up gfs2.  I'm confused because there are so many 'pieces' to this, I feel like I've lost my way?
    - To give a little background, I'm using an iSCSI target which allows any machine to make the SAN device a local scsi device on the system.  Ex: /dev/sdb   (This in turn allows direct block access, and I can do whatever with it; as if it were literally a system disk.)  I've read something about needing to set up fencing, cluster information, and .... ??  I'm lost. lol
    - I set up a partition with dlm compiled into the kernel (, and apparently I can only mount when using no_lock, dlm gives me a resource error (I'm assuming this has to do with no cluster information being set, or anything else configured).

2.  Is there a way to grow a gfs2 partition at the moment?  I see something for gfs1, yet no binaries, source, or references to a command except via this web page which outlines the command: http://www.die.net/doc/linux/man/man8/gfs2_grow.8.html

3. Quota.  Fortunately this is one of the last things I have to worry about on the chain of events that need to unfold.  I have not done much research on this last part as a result.  Does gfs's quota work like the quota system that .... well, I don't know if you want to call it a default, or generic, quota system .. or what?

Thank you greatly for your time and insight.  This project is a powerful resource, and I'm very appreciative of all the hard work people have put into it.
