Eric, thank you, that is what I wanted to know. I am using 4 brand new disks, so I do not plan on rebuilding for a time (I hope so!). Even in case of disk failure, is rebuild possible via Intel BIOS Utility?? Regards, Daniel <div>2008/1/28, Hall, Eric R <<a href="mailto:eric.r.hall@intel.com">eric.r.hall@intel.com</a>>:<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Daniel - Keep in mind that dm-raid4-5 is still considered 'experimental.' Raid5 would work fine in a home environment as long as you do not plan on rebuilding after a failure [at the moment]. Since the dm-raid4-5 patch is still considered experimental, you should weight your risks of data loss. I have tested Heinz's dm-raid4-5 patch on several ICH systems and have had good success with it; even after pulling a drive out to simulate a failure. If a failure would occur, you would have the opportunity to back-up the data before the set completely failed. Raid5 rebuild functionality isn't quite here yet. But it will be! Everyone is still working hard to update dmraid to rebuild failed sets. - Eric >-----Original Message----- >From: <a href="mailto:ataraid-list-bounces@redhat.com">ataraid-list-bounces@redhat.com</a> [mailto:<a href="mailto:ataraid-list-">ataraid-list-</a> ><a href="mailto:bounces@redhat.com">bounces@redhat.com</a>] On Behalf Of Daniel Guzmán >Sent: Monday, January 28, 2008 9:47 AM >To: ATARAID >Subject: Re: Intel ICH9R Raid5 supported? > >Brian, thank you very much for your response. > >Since this patch is Alpha (experimental) software, how reliable is it for a >home environment? >Is development status enough for being reasonably safe from data lost? >Regards. > > >2008/1/27, Wood, Brian J <<a href="mailto:brian.j.wood@intel.com">brian.j.wood@intel.com</a>>: > > Raid 5 is supported, but not in the base kernel as of yet (it's still >experimental).
