Linux 创建大于2T的分区(parted创建GPT分区)
作者:互联网
现在有一块12T的磁盘,需要分成三个区作为OpenStack的存储目录,分别为:
- /dev/sda1(6T):作为Nova实例存放目录/var/lib/nova/instances
- /dev/sda2(4T):存放Cinder数据卷存放分区
- /dev/sda3(2T):作为Swift对象存储使用分区
操作方法:
[root@openstack-controller ~]# parted /dev/sda ...... (parted) mklabel gpt # 更改为pgt分区 Warning: The existing disk label on /dev/sda will be destroyed and all data on this disk will be lost. Do you want to continue? Yes/No? yes (parted) print # 打印分区信息 Model: AVAGO MR9361-8i (scsi) Disk /dev/sda: 12.0TB Sector size (logical/physical): 512B/512B Partition Table: gpt # 确认为gpt Disk Flags: Number Start End Size File system Name Flags (parted) mkpart primary 0 6TB # 创建6TB分区 Warning: The resulting partition is not properly aligned for best performance. Ignore/Cancel? i (parted) mkpart primary 6TB 10TB # 创建4TB分区 (parted) mkpart primary 10TB 12TB # 创建2TB分区 (parted) print Model: AVAGO MR9361-8i (scsi) Disk /dev/sda: 12.0TB Sector size (logical/physical): 512B/512B Partition Table: gpt Disk Flags: Number Start End Size File system Name Flags 1 17.4kB 6000GB 6000GB primary 2 6000GB 10000GB 4000GB primary 3 10000GB 12.0TB 2001GB primary
(parted) quit
[root@openstack-controller ~]# lsblk # 验证
