This is a very real-world issue that I've run into several times. Chris Another cool thing about software raid is the ability to mirror at the partition level. In my main server, I have a six partition 100GB drive mirrored to a 500GB drive with the remaining 400 on the second un-mirrored and used for junk that I don't care about losing. Of course, if I wasn't cheap, I would have just bought 2 500GB drives and had done with but there you go. -- *Richard Thomas Consulting* 301 Murrel St Dickson, TN 37055 http://www.rtcons.com -- You received this message because you are subscribed to the Google Groups NLUG group.

You're almost always better off just using software raid.

Most forums say you're better off with software raid. Any thoughts? Also, do you get a lot of errors in your dmesg log in Ubuntu? I get an amd64_edac error because my board doesn't support ecc. I get an iommu error because my board doesn't support that either. I have an address collision with my first PCI device, and a MMIO error from shpchp. Fun stuff! :). This is on two new gigabye motherboards.
