mhvtl虚拟磁带库（提供软件包）

 分类： linux

                                  Mhvtl虚拟磁带库

1.安装开发工具（gcc make rpm-buid）

# yum groupinstall "Development tools"

 

2.需要安装kernel-devel

# yum install kernel-devel

 

3.将mhvtl源代码制作成rpm

# cd /tmp/

# tar xf mhvtl-2013-03-22.tgz

# cd mhvtl-1.4/

# rpmbuild -ta /tmp/mhvtl-2013-03-22.tgz

error: Failed build dependencies:

       lzo-devel is needed by mhvtl-utils-1.4-7.el6.x86_64

       zlib-devel is needed by mhvtl-utils-1.4-7.el6.x86_64

 

 

在制作rpm的过程中需要解决依赖性

# yum install zlib-devel

# ls

lzo-devel-2.03-3.1.el6.x86_64.rpm     

lzo-minilzo-2.03-3.1.el6.x86_64.rpm 

mhvtl-1.4                           

mhvtl-2013-03-22.tgz                

# yum localinstall lzo-*

 

再次安装过程会报错需要创建user vtl

# rpmbuild -ta /tmp/mhvtl-2013-03-22.tgz

# adduser vtl

 

 

再次执行命令得到RPM软件包

]# rpmbuild -ta /tmp/mhvtl-2013-03-22.tgz

# cd  ~/rpmbuild/

[root@localhost rpmbuild]# ls

启动mhvtl服务，但是会出现问题

[root@localhost x86_64]# service mhvtl start

 

Could not locate library config file: /etc/mhvtl/library_contents.10

Creating a default one

Please stop mhvtl & edit /etc/mhvtl/library_contents.10 to suit your requirements

 

Could not locate library config file: /etc/mhvtl/library_contents.30

Creating a default one

Please stop mhvtl & edit /etc/mhvtl/library_contents.30 to suit your requirements

FATAL: Module mhvtl not found.

No kernel module loaded to feed these daemons.

 

Need mhvtl kernel module version at least 0.18.11

 

Did you remember to compile the 'mhvtl' kernel module ?

 

Please see http://sites.google.com/site/linuxvtl2/

 

 

返回源代码目录，编译所需内核模块

[root@localhost x86_64]# cd /tmp/mhvtl-1.4/kernel

[root@localhost kernel]# ls

fetch24.c  fetch26.c  fetch27.c  fetch.c  Makefile  mhvtl.c  vtl_common.h

[root@localhost kernel]# make

[root@localhost kernel]# make install

[root@localhost kernel]# ls /lib/modules/2.6.32-358.el6.x86_64/kernel/drivers/scsi/mhvtl.ko

/lib/modules/2.6.32-358.el6.x86_64/kernel/drivers/scsi/mhvtl.ko

 

 

再次启动服务OK

[root@localhost kernel]# service mhvtl start

vtllibrary process PID is 8631

vtllibrary process PID is 8634

 

 

磁带库的磁盘所存放的位置，每一个目录就是一盘磁带

[root@localhost kernel]# cd /opt/mhvtl/

[root@localhost CLN101L4]# ls

data        数据文件

meta       设备描述文件

indx       索引文件

 

 

可以配置每个磁盘的大小

[root@localhost CLN101L4]# cd /etc/mhvtl/

[root@localhost mhvtl]# cat mhvtl.conf

# Default media capacity (500 M)       指定每个磁盘大小

CAPACITY=500 

 

#yum install lsscsi

使用lsscsi命令，我们可以看到2个虚拟磁带库
