Asianux + GFS

今天浅浅地介绍一下GFS的安装。非常简单。复杂，表问我，俺也不会。呵呵。
环境一台实机，一台虚拟机。装的Asianux 3.0
首先在 虚拟机里面：

cman-2.0.98-1.el5.i386.rpm
cman-devel-2.0.98-1.el5.i386.rpm
dkms-2.0.22.0-1.noarch.rpm
dkms-iscsi_sfnet-4.0.2-7fc5.i386.rpm
dkms-iscsi_trgt-0.4.13-1fs.i386.rpm
dkms-iscsi_trgt-0.4.13-2fc5.i386.rpm
gfs2-utils-0.1.53-1.el5.i386.rpm
gfs-utils-0.1.18-1.el5.i386.rpm
ibft-1.0.1-1fc5.i386.rpm
iscsi-initiator-utils-6.2.0.868-0.18.el5.i386.rpm
iscsitarget-0.4.13-2fc5.i386.rpm
iscsitarget-0.4.15.tar.gz
linux-iscsi-4.0.2-6fc5.i386.rpm
mkinitrd-iscsi-5.0.32-2.1fc5.i386.rpm
open-iscsi-2.0.713-11.i586.rpm
perl-Config-General-2.40-1.el5.noarch.rpm
perl-Net-Telnet-3.03-5.noarch.rpm
scsi-target-utils-0.0-5.20080917snap.el5.i386.rpm
Cluster_Administration-zh-CN-5.2-1.noarch.rpm
Global_File_System-zh-CN-5.2-1.noarch.rpm
isns-utils-0.91-0.1.el5.i386.rpm
kmod-gfs-0.1.31-3.el5.i686.rpm
piranha-0.8.4-11.el5.i386.rpm

      
        我们报着宁可错杀一千，不可露掉一个的态度，全装上再说，期间他们的依赖关系，我就不说了，这个很烦。
        由于空间有限。唉，我只好虚拟一个，临时 用用

dd if=/dev/zero of=gfs bs=1024k count=2000
losetup  /dev/loop1 gfs
[root@gfs ~]# blockdev  --getsize /dev/loop1

[root@gfs ~]# mkfs.gfs -p lock_nolock -j 3 /dev/loop1
[root@gfs ~]# mount /dev/loop1  /mnt/max/
[root@gfs ~]# df -hT
Filesystem    Type    Size  Used Avail Use% Mounted on
/dev/sda1     ext3    6.8G  4.5G  2.1G  69% /

/dev/hdc   iso9660    2.9G  2.9G     0 100% /media/RHEL_5.3 i386 DVD
/dev/loop1     gfs    1.6G  1.1M  1.6G   1% /mnt/max
[root@gfs ~]# 

        
        看来本机是可以用了，再拷点文件上去

[root@gfs ~]# ls /mnt/max/
cman-2.0.98-1.el5.i386.rpm        gfs2-utils-0.1.53-1.el5.i386.rpm           perl-Net-Telnet-3.03-5.noarch.rpm
cman-devel-2.0.98-1.el5.i386.rpm  perl-Config-General-2.40-1.el5.noarch.rpm
[root@gfs ~]#

 
     其次，在别的机子上挂载这个GFS 文件系统。
     记住，我们用的是kernel-2.6.18-128.el5.i686.rpm 这个内核。
    
     我们看看在虚拟机里的配置文件

[root@gfs ~]# !cat
cat /etc/ietd.conf | grep -v "#" | grep -v "^$"
Target iqn.2009-05.gfs:storage
        Lun 0 Path=/dev/loop1,Type=fileio
[root@gfs ~]#

[root@gfs ~]# /etc/init.d/iscsi-target start
[root@gfs ~]# dmesg   | grep loop1
Trying to join cluster "lock_nolock", "loop1"

GFS: fsid=loop1.0: jid=2: Looking at journal...
GFS: fsid=loop1.0: jid=2: Done
[root@gfs ~]#

        再看看端口
        

[root@gfs ~]# !lsof
lsof  -i:3260
COMMAND  PID USER   FD   TYPE DEVICE SIZE NODE NAME
ietd    7993 root    7u  IPv6  24656       TCP *:iscsi-target (LISTEN)
ietd    7993 root    8u  IPv4  24657       TCP *:iscsi-target (LISTEN)
[root@gfs ~]#

    客户端 要装 gfs-utils gfs2-utils kmod-gfs kmod-gfs2 等软件，有兴趣的话，上面的包全装吧。不要费多少 空间的。

至此 GFS 的基本安装己搞定，GFS 别的功能，请看官方文档（太多了，一时搞不定）。
