I am wondering what difference between the following two solutions is: - raid0 on top of 2 raid1 devices (raid1+0) - directly using the raid10 module Perhaps someone can give me a hint what the raid10 linux module does in= =20 difference to the combination of raid1 and raid0. Another question: How stable is the raid10 module in the linux kernel. I am currently=20 using the debian kernel 2.6.18 but I saw some patches from Neil and=20 others for 2.6.21, 2.6.22 regarding the raid10 module. And their=20 descriptions sound as if it could be useful to integrate them. when=20 using raid10. Okay, backporting isn't complicated, but nevertheless the number of=20 patches makes me feel that raid10 is perhaps not that stable like raid0= =20 and raid1 ??? Perhaps someone can blow away my fear :) Best regards Thimo Eichst=E4dt - 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
