New RAID configuration questions.
Posted on 2004-10-21
I'm looking to build a home hard drive server for myself. I bought the parts for a new box, so I can make it nothing but a server for myself.
I am going to configure RAID on it. I am thinking RAID 5 because I do want to be able to recover data if one drive fails (unlike RAID 0), but I don't want full copies (like RAID 1 or 0+1). I have movies, MP3's, ISO's, all the standard file share stuff; that's the primary use of it. I will be using gigabit to my main PC and hoping a RAID will help improve performance. I am sure I'm going with a software RAID, because although I have a cheap PCI controller and the motherboard supports RAID 0 & 1, I want all my hard drives to be one big RAID (excluding the samll system disk). I will be running Ubuntu Linux, and I'm sure Linux has the ability to run RAID 5 from software. My first question is: Is RAID 5 a good solution to what I want and stated above?
I am looking to configure this RAID on drives I am currently using (two 120GB IDE, one 160GB IDE, and one 80GB IDE). I have these drives absolutely full of data right now, and I'll be adding a new (one 160GB SATA) drive to it as well. The question here is: Can I impliment my new RAID without losing my data (since these drives are not empty), or will I have to back up all the data elsewhere and bring it back in?
Thanks in advance. Any help you can give me on the topic of RAID, Software RAID, and software RAID with Linux (Any recommendations on good Linux RAID software?) would be much appreciated, in addition to the two questions I asked.
