I use mdadm to manage a software RAID 5 array. The man page is thorough and there are plenty of online resources. There is no GUI that I know of, but you can set it up to self-monitor and e-mail you if there is a problem so I haven't really interacted with mdadm much since I got it up and running. Given the lack of time generally spent dealing with the array, I wouldn't go with hardware RAID unless you need it for the performance advantage (which is slight IMO if your CPU isn't maxed). -Scott <div>On 4/13/07, Bart Silverstrim <<a href="mailto:bsilver@chrononomicon.com">bsilver@chrononomicon.com</a>> wrote:<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> I'm working on assembling a new workstation for running Ubuntu. I am going to get a system running RAID 1. The system I've spec'd out is currently configured with a 3ware RAID card on advice from the vendor (rather than using the motherboard's built-in RAID... (Motherboard is an Asus P5N32-SLI SE Deluxe, 3ware card is a 3Ware 9650SE-2LP 2-port PCI-E SATA2 controller). I've used a 3Ware product before, and liked the ease with which I can access a graphical status of the card from the web page (3dm2?), plus 3ware support should be for the most part plug and play with current kernels and creating/managing the arrays, if all else fails, should be simple from the bootup screen's hotkey-setup on the controller; Linux wouldn't need to worry about managing the RAID disks because it would virtually invisible to the system. But I've also read that software RAID 1 under Linux should work well now too; the problem for me is monitoring/checking status in a quick and easy way (and doing setup, rebuilding, etc.). Questions: For software RAID, are there good tools to use for configuring/ monitoring/interacting with the volumes now? Graphical ones? Is the 3Ware worth the extra money to install, given that it's true hardware RAID and has 3dm and a CLI tool for configuration? It sounded like 3ware was well supported under Linux and generally reputable, and rebuilding/using the controller is a relatively no- hassle deal.
