1. Giải quyết nó
Tôi cũng gặp phải vấn đề này, và đây là cách tôi trấn áp cảnh báo khó chịu!
Điểm mấu chốt là: set the start to any logical sector, which is a multiple of 8 .
Tôi đặt 204800 (vì tôi chỉ có thể chọn từ 65535-976773167).
bước 1 fdisk
$ fdisk /dev/sdf
The device presents a logical sector size that is smaller than
the physical sector size. Aligning to a physical sector (or optimal
I/O) size boundary is recommended, or performance may be impacted.
欢迎使用 fdisk (util-linux 2.23.2)。
更改将停留在内存中，直到您决定将更改写入磁盘。
使用写入命令前请三思。
