Comment 14 for bug 1543704

I was encounter with this problem after I fix disk order with fdisk.

**before fix:**
Disk /dev/sda: 465.8 GiB, 500107862016 bytes, 976773168 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes
Disklabel type: dos
Disk identifier: 0xee678789

设备 启动 Start 末尾 扇区 Size Id 类型
/dev/sda1 * 2048 62916607 62914560 30G 83 Linux
/dev/sda3 62916608 976773119 913856512 435.8G f W95 扩展 (LBA)
/dev/sda5 79720448 976773119 897052672 427.8G 83 Linux
/dev/sda6 62918656 79720447 16801792 8G 82 Linux 交换 / Solaris

Partition table entries are not in disk order.
