So if I mirrored 2 drives linux would still see 2 drives instead of one? Well I guess seeing 4 more ide devices (up to anyway) is better than nothing. And in doing that have you noticed any performance loss? Thanks for the info...

Basically, what you do is set up a RAID partition when booting the system -- doesn't matter which kind, although it's slightly easier to set up what the BIOS thinks is a striped partition -- and then ignore it. Linux doesn't see the RAID drives as RAID drives, but as ordinary partitions. Then it's just a matter of setting up the software RAID in Linux itself, and choosing which file system you want to use. (I'm using ext3, and have yet to have any fsck problems, even though I've had to, on a couple of occasions, hit the reset button.) Overhead is apparently small, and Linux supports more kinds of RAID than the Promise chipset does, anyway. (Right now, I've got my / and /home directories on mirrored partitions, and my /var directory on a striped one.) -----Original Message----- From: tclug-list-admin at mn-linux.org [mailto:tclug-list-admin at mn-linux.org]On Behalf Of doug Sent: Wednesday, June 12, 2002 5:52 PM To: tclug-list at mn-linux.org Subject: [TCLUG] Promise ATA/Raid Hey is anyone successfully using that chipset in a raid configuration in Linux? I have an MSI board with an AMD 1.4ghz and the board has the promise 20265 lite chipset on it. (Link to the board below) Since win2k server has decided it doesn't want to be on there anymore I'd like to put RH 7.3 on it, and I'd like to mirror 2-40 gig drives with it. I seem to remember reading somewhere awhile ago that linux can see the raid chipset, but you can't actually raid any drives. Can anyone shed any light? http://www.msicomputer.com/product/detail_spec/product_detail.asp?model=K7T_266_PRO-R Thanks Doug _______________________________________________ Twin Cities Linux Users Group Mailing List - Minneapolis/St. Paul, Minnesota http://www.mn-linux.org tclug-list at mn-linux.org https://mailman.mn-linux.org/mailman/listinfo/tclug-list
