This appears to be common, also happens on Gnome, XFCE, and LXDE Live's Disk /dev/sda: 8589 MB, 8589934592 bytes 128 heads, 32 sectors/track, 4096 cylinders Units = cylinders of 4096 * 512 = 2097152 bytes Disk identifier: 0x000049eb Device Boot Start End Blocks Id System /dev/sda1 * 1 101 204800 83 Linux Partition 1 does not end on cylinder boundary. /dev/sda2 101 4095 8181098+ 8e Linux LVM Partition 2 does not end on cylinder boundary. UPDATE: I checked fdisk -lu output and see now that on _sector_ level they do not actually overlap but only on cylinder level. So there is NO problem here and the bug can be closed. But it is very strange/unusual to see partitions crossing cylinder boundaries... cylinders are an historical artefact, and have nothing to do with the actual physical disk layout now a days, so aligning to them has no use. In F-13, we will use some new kernel functions to query the actual physical disklayout of the disk, and start aligning to actual physical blocks (this is mostly relevant for the new and upcoming 4k physical sector disks). Yes, I realize that. It is just after 15+ years of manually creating partitions with fdisk I "got used to" seeing everything aligned to cylinder boundaries. Hence my confusion when I saw rootfs/swap overlapping on cylinder level. |
