linux 挂载3t硬盘分区,centos7挂载3T硬盘

相信很多人都遇到大硬盘无法全部格式化空间的问题,这里给大家说下怎么完全使用2T以上的硬盘空间.(这篇文章其实早就写好了的,因操作的时候没截图,一直没找到机会把图补上,所以大家降就看吧)

系统:centos7(64位)

1.先查看硬盘大小

fdisk -l

Disk /dev/vda: 214.7 GB, 214748364800 bytes, 419430400 sectors

Units = sectors of 1 * 512 = 512 bytes

Sector size (logical/physical): 512 bytes / 512 bytes

I/O size (minimum/optimal): 512 bytes / 512 bytes

Disk label type: dos

Disk identifier: 0x000d64b4

Device Boot      Start         End      Blocks   Id  System

/dev/vda1   *        2048   419430366   209714159+  83  Linux

Disk /dev/vdb: 3221.2 GB, 3221225472000 bytes, 6291456000 sectors

Units = sectors of 1 * 512 = 512 bytes

Sector size (logical/physical): 512 bytes / 512 bytes

I/O size (minimum/optimal): 512 bytes / 512 bytes

或者也可以用lsblk来进行查看

lsblk
