I have a 5-disk raid5. I notice that the five identical disks, which also list identical LBA numbers on the label, do not show the same size when queried. One is reporting (smart - it should tell the truth from the disk pov) a smaller size. One disk reports User Capacity: 1,000,203,804,160 bytes and the other four User Capacity: 1,000,204,886,016 bytes Luckily I always build a raid on partitions so this difference is irrelevant being in the slack past the partition end. However, if I managed to use the whole disk, the raid will be as large as the smallest disk. What happens when I replace a disk and get an even smaller replacement one? Do people always leave unused space at the end? Do you expect disks from the same exact model to have exactly the same usable size? BTW, even if the label gave the correct size, one does not know in advance what will arrive when you order a disk, right? cheers -- Eyal Lebedinsky (eyal@xxxxxxxxxxxxxx) -- 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
