檢視到/dev/sdc 沒有掛載，接下來建立掛載點（建立掛載目錄），我是臨時掛載暫時命名為linshi,我先掛載sdc1的可用空間.然後先mkfs命令-(make filesystem的縮寫；用來在特定的分割槽建立Linux檔案系統)建立linux檔案系統,才能執行mount命令，掛載資料盤。
[[email protected]]#mkfs.ext4 /dev/sdc1
[[email protected] ~]# mount /dev/sdc1 /linshi 掛載完成
使用df -h 命令檢視使用情況,發現多了個sdc1了
[[email protected] ~]# df -h

2、系統啟動，自動掛載資料盤
檢視磁碟UUID資訊
[[email protected] ~]# blkid
/dev/sda1: UUID="e52fb0a2-a2f4-4956-8b7f-7752dcd5e037" TYPE="ext4"
/dev/sdb: UUID="e28226c1-e2ea-4ccb-b8b4-b9d437c31a21" TYPE="ext4"
/dev/sdc1: UUID="2fced1fa-1a72-40e9-b49f-89026e367160" TYPE="ext4"
/dev/sdc2: UUID="0839b341-03a5-4757-9ac7-23deb135d767" TYPE="ext4"
編輯系統分割槽表
[[email protected]]# vi /etc/fstab
新增如下資訊：(將sdc1的uuid複製下來)
UUID=2fced1fa-1a72-40e9-b49f-89026e367160 /linshi ext4 defaults 1 2
編輯後的資訊如下

儲存退出；重啟系統，確認自動掛載成功。
