大于2T的硬盘怎么分区

使用parted工具：

#yum install parted

#parted /dev/sdb    //选择要分的硬盘

#(parted) mklabel   gpt //类型GPT

Warning: The existing disk label on /dev/sdb will be destroyedand all data on this disk will be lost. Do you want to continue?
Yes/No? y //确定

#(parted) mkpart prinmary 1 -1         //将硬盘分成一个分区

#(parted) print         //查看

#(parted) quit         //退出Information: You may need to update /etc/fstab.

#mkfs.ext4 /dev/sdb1 //格式化文件系统为ext4

GPT（全局唯一标识磁盘分区表，适合UEFI下启动的系统）与MBR（主引导记录，适合BIOS下启动的系统）不同，GPT只有主分区，没有逻辑分区

ipmitool和megacli这两款硬件维护工具，俗称业内“倚天剑”和“屠龙刀”

#megacli -PDList -aALL

#megacli -CfgLdAdd -r1 [252:0,252:1] WB Direct -a0

#megacli -CfgLdAdd -r1 [252:2,252:3] WB Direct -a0

此时/dev/下会多出  sdb 和 sdc，再进行分区就行。

#blkid   /dev/sdb

[root@node-1 ~]# parted  -l （查看所有磁盘状态）
