![分区对齐 8 TB 希捷 Ironwolf](https://linux22.com/image/145638/%E5%88%86%E5%8C%BA%E5%AF%B9%E9%BD%90%208%20TB%20%E5%B8%8C%E6%8D%B7%20Ironwolf.png)
我有一个希捷磁盘,我正在尝试对齐分区。我在parted中尝试过这个命令:
sudo parted /dev/sda mklabel gpt
sudo parted -a opt /dev/sda mkpart primary ext4 0% 100%
收到此 fdisk 错误:
Device Start End Sectors Size Type
/dev/sda1 65535 15628000379 15627934845 7.3T Linux filesystem
Partition 1 does not start on physical sector boundary.
如何在 parted 中获得此磁盘分区对齐方式?
(我也尝试过这个指南:https://rainbow.chard.org/2013/01/30/how-to-align-partitions-for-best-performance-using-parted/
不成功)

不要使用parted,因为它显然不适合这项工作。要对 GPT 磁盘进行分区,请使用gdisk
.或者,如果您的版本支持fdisk
GPT 分区,您也可以使用它。只需删除分区并创建新分区即可。使用 格式化分区mkfs.ext4
。请注意,这样做会破坏已写入磁盘的所有数据。
