vm 掛載新硬碟在CentOS 後，要重新Mount 硬碟
首先掛載新硬碟後，CentOS
#df -h //看出目前硬碟 掛載的 是 sda or sdb or sdc...?
#fdisk -l //看一下現在抓取到那些硬碟
#fdisk /dev/sdc //開始對剛掛載的sdc硬碟做fdisk初始化 ----看※注意事項1
#mkfs.ext3 -L data40G /dev/sdc1 //對sdc 硬碟做格式化 這裡用3是因為 這台OS 是centos 5 如果是6.5 你可以用4
#blkid // 再檢查剛加進來的 sdc 是否已可正常觀看 uuid是多少
#mkdir /data1 //建立 要mount 的目錄位置
#vi /etc/fstab //修改 fstab 檔案 這邊是要開機掛載的硬碟紀載資訊 ----看※注意事項2
#mount -a //直接掛載fstab所記載的硬碟資訊
#df -h //做最後檢查 看看有沒正常掛載硬碟
※注意事項1 [初始化設定]---這部分因自身設定時，沒拍圖 故複製網路所找尋到的資料

Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel

Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won't be recoverable.
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)
WARNING: DOS-compatible mode is deprecated. It's strongly recommended to
switch off the mode (command 'c') and change display units to
sectors (command 'u').
