If at any time in this message you think I need to go back and RTFM please stop reading and let me know that. This is the sample config for RAID-5 that I am referring to: drive e device /dev/da6h volume raid5 plex org raid5 512k sd length 128m drive a sd length 128m drive b sd length 128m drive c sd length 128m drive d sd length 128m drive e I have a couple of questions about this. Is this config only slicing up one drive? That is what I gather from the config but the theory behind RAID-5 is that you need at least 3 for there to be a point in using RAID-5. So one of my many questions is that where do the drive a, drive b, drive c, drive d, and drive e 's come from? Are there seperated statements for those devices like there is for the drive e? Something such as drive a devide /dev/da0h? I guess I am just confused. Let me hit you up with the scenario that I am trying to use RAID-5 in. I have 4 external seagate drives of 23gigs each. I want to use those 4 drives in a RAID-5 array. They are da0 through da3. The drive where the OS sits is da4. I am wondering what I need to do to get RAID-5 running across those four drives. Thanks for all of your help. I appreciated it. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
