我的/dev/sdb有20T 该如何分区
yum install parted
1)fdisk 不能对其进行分区，因为只支持2T\
但是fdisk delete分区的操作还是可以的
fdisk -l 可能看不了 操作2T磁盘的分区情况
需要改用parted -l
2)parded命令可以对其进行GPT格式的分区
命令:
parted /dev/sdb 交互式进入去分区
mklabel gpt 将MBR磁盘格式化为GPT
mkpart primary 0 10T 分一个10T的
mkpart primary 10T -1 和一个将最后所有分区分到这个分区
格式化
mkfs.ext4 /dev/sdb1
10T的磁盘大概需要格式化三分钟
