1.新添加两个磁盘
Disk/dev/sdb: 21.5 GB, 21474836480 bytes
255heads, 63 sectors/track, 2610 cylinders
Units= cylinders of 16065 * 512 = 8225280 bytes
Sectorsize (logical/physical): 512 bytes / 512 bytes
I/Osize (minimum/optimal): 512 bytes / 512 bytes
Diskidentifier: 0x00000000

通过parted 对大于2TB的磁盘进行分区:
模拟兼容2T以上磁盘分区方式
parted /dev/sdb mklabel gpt yes
parted /dev/sdb mkpart primary ext4 0 1000 ignore
parted /dev/sdb mkpart primary ext4 1001 2000 Yes ignore
parted /dev/sdb p
主节点:
[root@node110 ha.d]#parted /dev/sdb mklabel gpt #调整分区表为GPT模式
Warning: The existingdisk label on /dev/sdb will be destroyed and all data on this disk will
be lost. Do you wantto continue?
Yes/No? Yes
Information: You mayneed to update /etc/fstab.
[root@node110 ha.d]#parted /dev/sdb mkpart primary ext4 0 10000 ignore #分第一个主分区 10G
Warning: The resultingpartition is not properly aligned for best performance.
Information: You mayneed to update /etc/fstab.
[root@node110 ha.d]#ll /dev/sdb*

[root@node110 ha.d]#parted /dev/sdb mkpart primary ext4 10001 20000 ignore #分第二个分区 10G
Warning: The resultingpartition is not properly aligned for best performance.
