千家信息网最后更新 2025年12月02日Linux下parted对磁盘进行分区今天为了挂载文件系统，对磁盘进行分区，磁盘大小3.6TB。
使用fdisk对磁盘分区完成之后，查看如下：
Disk /dev/sdb: 3598.9 GB, 3598914158592 bytes
255 heads, 63 sectors/track, 437543 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000
Device Boot Start End Blocks Id System
/dev/sdb1 1 234976 1887444688+ 83 Linux
/dev/sdb2 234977 267349 260036122+ 5 Extended

发现最大只能识别260036122Blocks，3.6TB的磁盘没有完全分完，经查阅资料，使用fdisk进行分区最大只能识别2TB，于是采用parted进行分区。

分区已经完成，下一步可以进行格式化并挂载文件系统
mkfs -t ext4 /dev/sdb1
mkfs -t ext4 /dev/sdb2
