linux下挂载大小超过2T存储的方法

附件大文件等应用需要直接部署到存储上，安装linux时建议把所有包全勾选上，如果采用默认安装，不同厂家的存储驱动将会很难装上，提示系统少包，甚至少什么包都不太清楚。当把存储分配给你的HBA光纤卡后，在服务器上装好HBA卡驱动并重启系统，就可以用fdisk -l命令查看存储信息了。 在使用存储之前需要对存储进行分区操作，在RHEL5.4上用fdisk命令分区最大磁盘分区只能在2T以下，故以下采用parted对存储进行分区：（红色部分代表需要输入的命令）rootoa-1 # fdisk l /查看磁盘信息WARNING: GPT (GUID Partition Table) detected on /dev/sda!
