BTW, have you ever resized a software RAID on Windows XP (I have). That is different but way harder, plus it required using Linux tools.
Am ready to give you my server pass and to make it for me.
contact me at b.sejdini(at)yahoo.com if you can help me with this.
One item I didn't mention in this thread (I did in your other thread). Most of that work cannot be done while your server is booted normally. You need to shut it down and boot something such as a Linux bootable CD, then do all the partition resizing while that CD is booted. That makes it a bit trickier (I don't think impossible) for you do give control to someone remotely to do the commands for you.
My own skill level is high enough to blunder through something like this in person (I have done many similar tasks that way) but not nearly high enough to deal with the extra challenge of working remotely.
Since the system is so new, what is wrong with the plan of wipe it all out and install Centos (or Ubuntu if you really prefer) from scratch partitioned whatever way you want?
But looking at your other thread also made me realize you don't really need/want to mess with resizing md3. You really want to delete md3.
You can easily copy all of /home from md3 to some other directory on md2. Later you can dismount and eliminate /home and rename that other directory as /home. Then delete md3, sda5, sda4, sdb5 and sdb4. I think all that might even be doable while the full system is booted normally (as long as ordinary users aren't logged in).
Then growing md2 should be somewhat simpler with sda4 and sdb4 completely gone. Growing md2 would still require being booted from something else.
