一:配置相關環境,編譯安裝mhvtl.tgz(linux 虛擬帶庫)
- [root@rhel6 src]# tar -zxvf mhvtl.tgz
- [root@rhel6 src]# cd mhvtl-0.18/
- [root@rhel6 mhvtl-0.18]# yum -y install zlib-devel mtx mt-st lsscsi
- [root@rhel6 mhvtl-0.18]# useradd vtl
- [root@rhel6 mhvtl-0.18]# echo '123456' |passwd --stdin vtl
- Changing password for user vtl.
- passwd: all authentication tokens updated successfully.
- [root@rhel6 mhvtl-0.18]# mkdir /opt/mhvtl //虛擬帶庫存儲路徑
- [root@rhel6 mhvtl-0.18]# mkdir /etc/mhvtl //配置文件路徑
- [root@rhel6 mhvtl-0.18]# chown -R vtl.vtl /opt/mhvtl/ /etc/mhvtl/
- [root@rhel6 mhvtl-0.18]# cd kernel/ //需要安裝kernel-devel和kernke-headers軟件包,否則以下編譯會報錯
- [root@rhel6 kernel]# ls
- fetch24.c fetch26.c fetch27.c fetch.c Makefile mhvtl.c mhvtl-kmod.spec vtl_common.h
- [root@rhel6 kernel]# make && make install
- [root@rhel6 kernel]# modprobe mhvtl
- [root@rhel6 kernel]# lsmod |grep mhvtl

- [root@rhel6 kernel]# cd ..
- [root@rhel6 mhvtl-0.18]# make && make install

三:使用磁帶機,nst0代表不回卷設備
- 1.將數據歸檔到模擬磁帶機
- [root@rhel6 media]# mt -f /dev/nst0 tel
- At block 0.
- [root@rhel6 media]# tar -cvf /dev/nst0 張敬軒\ -\ 定局\ -\ 盛世仁傑主題曲.mp3
- 張敬軒 - 定局 - 盛世仁傑主題曲.mp3
- [root@rhel6 media]# mt -f /dev/nst0 tel
- At block 350.
- 2.倒帶至磁帶頭並查看磁帶內容,查看完內容後,會把磁帶指針停止在內容位置後
- [root@rhel6 media]# mt -f /dev/nst0 rewind
- [root@rhel6 media]# mt -f /dev/nst0 tel
- At block 0.
- [root@rhel6 media]# tar -tvf /dev/nst0
- -rw-r--r-- nobody/nobody 3569715 2010-07-26 04:54 張敬軒 - 定局 - 盛世仁傑主題曲.mp3
- [root@rhel6 media]# mt -f /dev/nst0 tel
- At block 349.
- 3.繼續添加文件至磁帶機
- [root@rhel6 media]# tar -cvf /dev/nst0 /boot/vmlinuz-2.6.32-71.el6.x86_64
- /boot/vmlinuz-2.6.32-71.el6.x86_64
- [root@rhel6 media]# mt -f /dev/nst0 tel
- At block 721.
- 4.從磁帶機中導出歸檔文件
- [root@rhel6 media]# mt -f /dev/nst0 rewind
- [root@rhel6 media]# tar -tvf /dev/nst0
- -rw-r--r-- nobody/nobody 3569715 2010-07-26 04:54 張敬軒 - 定局 - 盛世仁傑主題曲.mp3
- [root@rhel6 media]# mt -f /dev/nst0 rewind
- [root@rhel6 media]# rm -i 張敬軒\ -\ 定局\ -\ 盛世仁傑主題曲.mp3 //刪除本地文件
- rm: remove regular file `張敬軒 - 定局 - 盛世仁傑主題曲.mp3'? y
- [[root@rhel6 media]# tar -xvf /dev/nst0 //導出第一個文件
- 張敬軒 - 定局 - 盛世仁傑主題曲.mp3
- [root@rhel6 media]# tar -xvf /dev/nst0 //導出第二個文件
- boot/vmlinuz-2.6.32-71.el6.x86_64
- 驗證:
- [root@rhel6 media]# ls
- boot 張敬軒 - 定局 - 盛世仁傑主題曲.mp3
- [root@rhel6 media]# ls boot/
- vmlinuz-2.6.32-71.el6.x86_64
- 5.清除磁帶機中的數據並倒帶至磁帶頭
- [root@rhel6 media]# mt -f /dev/nst0 erase
- [root@rhel6 media]# mt -f /dev/nst0 tel
- At block 0.
四:卸載磁帶機
- [root@rhel6 media]# mtx -f /dev/sg11 unload 1 0
- Unloading drive 0 into Storage Element 1...done
