Well, I know the 0.90 superblock limits the COMPONENT devices to 2TB, but I know for a fact it doesn't limit the array itself to 2TB, at least not using mdadm 2.6.7.2, because I have created arrays much larger than 2T using a 0.90 superblock. There is also a limit of 28 component devices using a 0.90 superblock, but you are nowhere near that limit. Nonetheless, why not try using a 1.x superblock, instead? It can't hurt to try. What version of mdadm are you using? I'm using a 2.6.26-2 kernel, so I would think 2.6.29.5 would not have any limitations that 2.6.26 doesn't. -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
