使用parted命令对大容量盘进行分区及挂载
MBR分区表：（MBR含义：主引导记录）
所支持的最大卷：2T （T; terabytes,1TB=1024GB）
对分区的设限：最多4个主分区或3个主分区加一个扩展分区。
GPT分区表：（GPT含义：GUID分区表）
支持最大卷：18EB，（E：exabytes,1EB=1024TB）
每个磁盘最多支持128个分区
对新磁盘进行分区

Error: /dev/sdh: unrecognised disk label
Model: DGC VRAID (scsi)
Disk /dev/sdh: 2684GB
Sector size (logical/physical): 512B/512B
Partition Table: unknown
Disk Flags:
(parted) mklabel gpt #设置分区类型为gpt
Error: Input/output error during read on /dev/sdh
Retry/Ignore/Cancel? Ignore #忽略错误
# 整个分区流程如下：
[root@Node01 /]# parted /dev/sdh
(parted) p #可以输入p或print打印磁盘信息，查看分区的情况，找到起始和结束位置。
(parted) mklabel gpt #设置分区类型为gpt
(parted) mkpart primary 0% 100% #primary指分区类型为主分区，0是分区开始位置，100%是分区结束位置。相同的命令为：mkpart primary 0 XXXXXX结束的空间
(parted) quit #完成后用quit命令退出。

在退出之前可以先print一下，打印当前分区,查看分区设置是否正确。
格式化磁盘
操作完以上，即可对新分区进行格式化操作，
mkfs.xfs /dev/sdb1格式化完成后即可进行挂载。
通过使用blkid命令可以查看到当前的硬盘分区信息：
[root@Kuboard ~]# mkfs.xfs /dev/sdb1
meta-data=/dev/sdb1 isize=512 agcount=4, agsize=134217600 blks
= sectsz=512 attr=2, projid32bit=1
