1、远程SSH登录上CentOS服务器后，进行如下操作提醒：挂载操作会清空数据，请确认挂载盘无数据或者未使用第一步：列出所有磁盘命令：II/dev/disk/by・path[root@ZSJ_SERVERl~]#II/dev/disk/by-pathtotal0Irwxrwxrwx.1rootroot9Apr1409:52pci-0000:00:01.1-scsi-l:0:l:0->../../srOIrwxrwxrwx.1rootroot10Apr1409:52xen-vbd-51712->../../xvdaIrwxrwxr

7、查看fdisk命令帮助;n：命令创建一个新分区；P：命令显示分区列表；t：命令修改分区的类型ID号；w：命令是将对分区表的修改存盘让它发生作用。第二步：格式化硬盘命令：fdisk/dev/xvde[rootglocalhost4(disk/dev/sdbDevicecontainsneith"avalidDOSpartitiontablernorSun,SGIorOSFdisklabelBuildinganewDOSdisklabelwithdiskidentifier0x05fc0b35.Changeswillremain
