As every part of the array contains it's own metadata, it doesn't matter to md which /dev/sdX a drive is. It might matter a bit for boot-time assembly, but actually that's what UUIDs are for. >=20 > The page is still not really finished, I am still playing with my > server so the documentation must wait. >=20 >=20 > Michael McCallister napsal(a): >=20 >> So with four drives sda, sdb, sdc, and sdd and two controllers C1 an= d >> C2, should >> I go with >> >> C1: sda, sdb >> C2: sdc, sdd >> >> or >> >> C1: sda, sdc >> C2: sdb, sdd >> >> or some other configuration? >> =20 But I understand yours, Michael. You would like to put those RAID0-pieces of your RAID10 each on a single controller. I believe one must find out what "NEAR" and "FAR" is. I'd understand it as: "NEAR" is the closer disk - yeah. Closer in the array-tree, or it's logical base-LBA is closer? Neil, could you please clarify which is which? >=20 > --=20 > To unsubscribe from this list: send the line "unsubscribe linux-raid"= in > the body of a message to majordomo@vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html All the best, Stefan -- To unsubscribe from this list: send the line "unsubscribe linux-raid" i= n the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
