MagnusDredd asks: "I am trying to build a large home drive array on the cheap. I have 8 Maxtor 250G Hard Drives that I got at Fry's Electronics for $120 apiece. I have an old 500Mhz machine that I can re-purpose to sit in the corner and serve files. I plan on running Slackware on the machine, there will be no X11, or much other than SMB, NFS, etc. I have worked with hardware arrays, but have no experience with software RAIDs. Since I am about to trust a bunch of files to this array (not only mine but I'm storing files for friends as well), I am concerned with reliability. How stable is the current RAID 5 support in Linux? How hard is it to rebuild an array? How well does the hot spare work? Will it rebuild using the spare automatically if it detects a drive has failed?"
