StorNext FS 配置

(Red Hat Enterprise Linux/x86 AS 4 +win2K)

一、环境描述:

硬件描述:

1. Brocade 3950

2. S2A 8000(本例中3个LUN,分别为MetaData(30GB)、Journal(100MB)、数据)

3. DELL 2650 (内存 2G,建议4G)

软件描述:

1. Red Hat Enterprise Linux/x86 AS 4 update 1 (2.6.9-11)

2. StorNext FS Server/Client 软件

二、StorNext FS系统配置

1准备工作

1.1配置网络

# vi /etc/hosts

127.0.0.1 localhost.localdomain localhost

10.0.5.25 mds1 //这里为两台MDS

10.0.5.26 mds2

1.2 安装Emulex LP8000/982驱动和应用程序

安装驱动程序 tar xzf lpfc-<driver version>.tar.gz //解压安装包

如:#tar zxvf lpfc_2.6_driver_kit-8.0.16.17-2.tar.gz

#cd lpfc_2.6_driver_kit-8.0.16.17-2

#./lpfc-install //执行安装脚本

#reboot //重起服务器

注意:Red Hat Enterprise Linux/x86 4 updata 1 内核中已经加载Emulex LP8000/982驱动,可以不做这一步。

如果在安装驱动程序中,报IO和IRQ参数错,检查Firmware版本,升级为最新的版本。

安装emulex hbanyware应用程序

#tar xvf elxlinuxapps-2.1a25-8.0.16.17-1-1.tar

#./install //安装emulex hnanyware

#/usr/sbin/hbanyware/hbanyware //运行emulex hnanyware,查看WWN,硬件信息。

注意:需要使用emulex hnanyware时需要安装lpfc_2.6_driver_kit-8.0.16.17-2.tar.gz程序,而linux 系统自带的LPFC的驱动不能被emulex hnanyware所以识别。

1.3 效验HBA卡加载。

通过cat /proc/scsi/scsi 命令查看HBA卡检测到的磁盘信息

# cat /proc/scsi/scsi

Host: scsi0 Channel: 00 Id: 06 Lun: 00

Vendor: PE/PV Model: 1x5 SCSI BP Rev: 1.1

Type: Processor ANSI SCSI revision: 02

Host: scsi2 Channel: 00 Id: 00 Lun: 03

Vendor: DDN Model: S2A 8000 Rev: 5.02

Type: Direct-Access ANSI SCSI revision: 03

Host: scsi2 Channel: 00 Id: 00 Lun: 08

Vendor: DDN Model: S2A 8000 Rev: 5.02

Type: Direct-Access ANSI SCSI revision: 03

1.4 效验SCSI、RAID、HBA卡加载顺序 --------此步骤在redhat AS 4以后的版本中,不需要做。

下面的例子是redhat as 3 update4

如果SCSI、RAID卡的加载在HBA卡后面。不然在本地SCSI系统盘的SWAP分区,不可用。如下

#cat /etc/module.conf

alias scsi_hostadapter lpfc // Emulex HBA

alias scsi_hostadapter1 aic7xxx //scsi卡

alias usb-controller usb-ohci

options scsi_mod max_scsi_luns=256 scsi_allow_ghost_devices=1

需要将加载顺序改变,如

alias scsi_hostadapter1 aic7xxx //scsi卡

alias scsi_hostadapter2 lpfc // Emulex HBA

alias usb-controller usb-ohci

options scsi_mod max_scsi_luns=256 scsi_allow_ghost_devices=1

重建内核

# cd /boot

# mv initrd-2.4.21-27.ELsmp.img initrd-2.4.21-27.ELsmp.img.ori

# mkinitrd initrd-2.4.21-27.ELsmp.img 2.4.21-27.ELsmp

# sync

# reboot

2安装StorNext FS

2.1 以root用户登录Linux,插入StorNext FS CD

#cd /mnt/cdrom

如果CDROM没有被mounted,那么执行#mount /dev/cdrom /mnt

# cd /mnt/cdrom/StorNextFS/linux //此路径根据实际情况而定

#uname -a 查看当前系统内核的版本。

如:uname -a

Linux mds01 2.6.9-11.ELsmp #1 SMP Fri May 20 18:26:27 EDT 2005 i686 i686 i386 GNU/Linux

# rpm -ivh snfs-server_RH_AS_4_269-2.6.3-32.i386.rpm

# rpm –ivh snfs-client_RH_AS_4_269-2.6.3-32.i386.rpm

注意,在linux上服务器上必须安装Server和client两个软件。

2.2 修改环境变量

#vi /etc/profile

# Path manipulation

if [ `id -u` = 0 ]; then

pathmunge /usr/cvfs/bin

fi

ulimit -S -c 0 > /dev/null 2 > &1

ulimit -c unlimited > /dev/null 2 >&1

注销root用户,重新以root用户登陆系统,才能使环境变量起作用

2.3 磁盘Label

2.3.1 查看盘阵信息,执行fdisk -l

# fdisk –l

Disk /dev/sdc (Sun disk label): 0 heads, 0 sectors, 52221 cylinders

Units = cylinders of 1 * 512 bytes

Device Flag Start End Blocks Id System

/dev/sdc3 u 0 -872571904 -436285952 5 Whole disk

Note: sector size is 2048 (not 512)

Disk /dev/sdg (Sun disk label): 0 heads, 0 sectors, 959 cylinders

Units = cylinders of 1 * 512 bytes

Device Flag Start End Blocks Id System

/dev/sdg3 u 0 62902272 31451136 5 Whole disk

Disk /dev/sdl (Sun disk label): 0 heads, 0 sectors, 2 cylinders

Units = cylinders of 1 * 512 bytes

Device Flag Start End Blocks Id System

/dev/sdl3 u 0 192512 96256 5 Whole disk

2.1查看disk Label

#/usr/cvfs/bin/cvlabel –l

/dev/sdc [DDN S2A 8000 5.02] CVFS " unknown " Sectors: 3422394368.

SectorSize: 1024. Maximum sectors: 3422394368.

/dev/sdg [DDN S2A 8000 5.02] CVFS " unknown " Sectors: 62900224.

SectorSize: 512. Maximum sectors: 62900224.

/dev/sdl [DDN S2A 8000 5.02] CVFS " unknown " Sectors: 190464. S

ectorSize: 512. Maximum sectors: 190464.

2.2 编辑disk Label配置文件

# /usr/cvfs/bin/cvlabel -c > /usr/cvfs/config/cvlabels

//将cvlabel输出到cvlabels配置文件中

# vi /usr/cvfs/config/cvlabels

将unkown更改为H_Upload,MD_H_Upload, JR_H_Upload。。。等,如本例中:

H_Upload /dev/sdc # host 0 lun 0 sectors 3422394368 sector_size 1024 inquiry [DDN S2A 8000 5.02] serial 60001FF020021101030197FECD180000

MD_H_Upload /dev/sdg # host 0 lun 4 sectors 62900224 sector_size 512 inquiry [DDN S2A 8000 5.02] serial 60001FF0200211010301932703C00400

JR_H_Upload /dev/sdl # host 0 lun 9 sectors 190464 sector_size 512 inquiry [DDN S2A 8000 5.02] serial 60001FF020021101030194A700030900

2.3 disk Label

# /usr/cvfs/bin/cvlabel /usr/cvfs/config/cvlabels

*WARNING* This program will over-write volume labels on the

devices specified in the file "/usr/cvfs/config/cvlabels".

After execution, the devices will only be usable by the

CentraVision File System. You will have to re-partition the

devices to use them on a different file system.

Do you want to proceed? (Y / N ) -> y

/dev/sdc [DN S2A 8000 5.02] CVFS " unknown " Sectors: 3422394368.

Do you want to label it SNFS - Name: H_Upload Sectors: 3422394368? (Y / N ) ->y

New Volume Label -Device: /dev/sda SNFS Label: H_Upload Sectors: 3422394368.

/dev/sdg [DN S2A 8000 5.02] CVFS " unknown " Sectors: 62900224.

Do you want to label it SNFS - Name: MD_H_Upload Sectors: 62900224? (Y / N ) ->y

New Volume Label -Device: /dev/sdb SNFS Label: MD_H_Upload Sectors: 62900224.

/dev/sdl [DN S2A 8000 5.02] CVFS " unknown " Sectors: 190464.

Do you want to label it SNFS - Name: JR_H_Upload Sectors: 190464? (Y / N ) ->y

New Volume Label -Device: /dev/sdb SNFS Label: JR_H_Upload Sectors: 190464.

Done. 3 source lines. 3 labels.

3. 配置StorNext FS

3.1创建StorNext FS文件系统的配置文件,

若查看参数信息,键入#man -M /usr/cvfs/man cvfs_config

# cd /usr/cvfs/config

#cp .. /examples/example.cfg ./H_Upload.cfg //例程中拷贝出文件系统的配置文件

# vi /usr/cvfs/config/H_Upload.cfg

3.2 创建文件系统配置文件列表的文件

# cd /usr/cvfs/config

# cp ../examples/fsmlist.example ./fsmlist

//例程中拷贝出文件系统配置文件列表的配置文件

#vi /usr/cvfs/config/fsmlist

// 其中的 . 表示当前机器的ip地址,0是优先,可为一个0~7. 但当前默认的为0是activate

3.3 创建文件系统配置服务器列表的文件

# cd /usr/cvfs/config #cp ../examples/fsnameservers.example ./fsnameservers

//将当前的StorNext FS文件系统的服务器的ip写入fsnameservers

如: 10.5.0.25

10.5.0.26

在做群集时,可以将每台服务器ip加入进来.并保持每一台的fsnameservers文件一致

* 表示激活

如果没有显示文件系统名称, 一般需要重新启动cvfs服务或检查fsmlist配置

或者手动启动,如下
