RE: Intel ICH9R Raid5 supported?

Daniel - Nope. The Intel Matrix RAID Option ROM simply creates/modifies metadata on the disks; it's up to an OS level utility [dmraid] to rebuild a set. Hopefully by the time you would need to rebuild, dmraid will support it! At least, I hope so! - Eric >-----Original Message----- >From: ataraid-list-bounces@xxxxxxxxxx [mailto:ataraid-list- >bounces@xxxxxxxxxx] On Behalf Of Daniel Guzmán >Sent: Thursday, January 31, 2008 11:55 AM >To: ATARAID >Subject: Re: Intel ICH9R Raid5 supported? > >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 > > >2008/1/28, Hall, Eric R <eric.r.hall@xxxxxxxxx>: > > 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].
