配置共享存儲和UDEV存儲設備綁定

2013年7月29日,星期一

1.vrh2新建磁盤

前提條件：vrh3主機需要是關閉狀態

共享磁盤必須使用固定大小磁盤類型，否則無法把其設置為共享類型

將以上四個磁盤設置為可共享的類型

點擊“管理”->“虛擬介質管理”->選擇磁盤->選擇類型為共享

在virtual Box管理器上顯示可能會有一點延遲

打開主機的I/O Cache

2.vrh3添加現有磁盤

添加磁盤并且打開主機的I/O Cache

3.在vrh2上綁定存儲磁盤

3.1把sdb 3G這個盤劃分成兩個分區

[root@vrh2 ~]# fdisk /dev/sdb

Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel

Building a new DOS disklabel. Changes will remain in memory only,

until you decide to write them. After that, of course, the previous

content won't be recoverable.

Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)

The new table will be used at the next reboot.

Syncing disks.

[root@vrh2 ~]# partprobe /dev/sdb

[root@vrh2 ~]# ls -l /dev/sdb*

brw-r----- 1 root disk 8, 16 Jul 29 07:39 /dev/sdb

b rw-r----- 1 root disk 8, 17 Jul 29 07:40 /dev/sdb1   #記住8,17  8,18 之后綁定會用到

b rw-r----- 1 root disk 8, 18 Jul 29 07:40 /dev/sdb2   #注意這里的sdb目前還是塊設備，我們之后會把它設置為raw設備

3.2綁定磁盤sdb

[root@vrh2 ~]# cd /etc/udev/rules.d/

[root@vrh2 rules.d]# vi 60-raw.rules

# Enter raw device bindings here.

#

# An example would be:

#   ACTION=="add", KERNEL=="sda", RUN+="/bin/raw /dev/raw/raw1 %N"

# to bind /dev/raw/raw1 to /dev/sda, or

#   ACTION=="add", ENV{MAJOR}=="8", ENV{MINOR}=="1", RUN+="/bin/raw /dev/raw/raw2 %M %m"

# to bind /dev/raw/raw2 to the device with major 8, minor 1.

ACTION=="add", KERNEL=="sdb1", RUN+="/bin/raw /dev/raw/raw1 %N"

ACTION=="add", KERNEL=="sdb2", RUN+="/bin/raw /dev/raw/raw2 %N"

ACTION=="add", KERNEL=="raw*", OWNER=="oracle", GROUP=="oinstall", MODE=="0660"             #把權限賦予給oracle用戶和oinstall用戶組

[root@vrh2 rules.d]# start_udev

Starting udev: [  OK  ]

[root@vrh2 rules.d]# cd /dev/raw

[root@vrh2 raw]# ls -l

total 0

crw-rw---- 1 oracle oinstall 162, 1 Jul 29 07:56 raw1

crw-rw---- 1 oracle oinstall 162, 2 Jul 29 07:56 raw2

3.3把sdc、sdd、sde綁定成asm文件格式

使用以下腳本可以實現，注意該腳本要在/dev/raw目錄執行

for i in b c d e f g h i j k ;

do

echo "KERNEL==\"sd*\", BUS==\"scsi\", PROGRAM==\"/sbin/scsi_id -g -u -s %p\", RESULT==\"`scsi_id -g -u -s /block/sd$i`\", NAME=\"asm-disk$i\", WNER=\"oracle\", GROUP=\"oinstall\", MODE=\"0660\""

done

我們這里只有cde三個盤，只需要將in后面寫上c d e即可，

解釋：

sbin/scsi_id -g -u   該號是唯一的，所以根據它來綁定

[root@vrh2 raw]# ls

raw1  raw2

[root@vrh2 raw]# for i in c d e;

> do

> echo "sd$i" "`scsi_id -g -u -s /block/sd$i`";

> done

sdc SATA_VBOX_HARDDISK_VBb86af276-b24615a9_

sdd SATA_VBOX_HARDDISK_VB453dbb62-ac2d0a41_

sde SATA_VBOX_HARDDISK_VB2a60d1f8-c1fd7b46_

執行腳本

[root@vrh2 raw]# for i in c d e;

> do

> echo "KERNEL==\"sd*\", BUS==\"scsi\", PROGRAM==\"/sbin/scsi_id -g -u -s %p\", RESULT==\"`scsi_id -g -u -s /block/sd$i`\", NAME=\"asm-disk$i\", WNER=\"oracle\", GROUP=\"oinstall\", MODE=\"0660\""

> done

KERNEL=="sd*", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u -s %p", RESULT=="SATA_VBOX_HARDDISK_VBb86af276-b24615a9_", NAME="asm-diskc", OWNER="oracle", GROUP="oinstall", MODE="0660"

[root@vrh2 rules.d]# start_udev

Starting udev: [  OK  ]

[root@vrh2 rules.d]# ls -l /dev/asm*

brw-rw---- 1 oracle oinstall 8, 64 Jul 29 20:30 /dev/asm-diske

4.在vrh3上綁定存儲磁盤

4.1啟動vrh3

4.2復制剛才配置的vrh2上的規則文件到vrh3

[root@vrh2 rules.d]# scp 60-raw.rules vrh3:/etc/udev/rules.d

The authenticity of host 'vrh3 (192.168.1.103)' can't be established.

RSA key fingerprint is 92:e1:fc:a6:f8:15:37:27:7b:50:41:fa:be:4d:19:0b.

Are you sure you want to continue connecting (yes/no)? yes

Warning: Permanently added 'vrh3,192.168.1.103' (RSA) to the list of known hosts.

root@vrh3's password:

60-raw.rules                                    100%  527     0.5KB/s   00:00   

[root@vrh2 rules.d]# scp 99-oracle-asmdevices.rules vrh3:/etc/udev/rules.d

root@vrh3's password:

4.3啟動服務

[root@vrh3 rules.d]# start_udev

Starting udev: [  OK  ]

[root@vrh3 rules.d]# ll /dev/raw/raw*

crw-rw---- 1 oracle oinstall 162, 1 Jul 29 20:39 /dev/raw/raw1

crw-rw---- 1 oracle oinstall 162, 2 Jul 29 20:39 /dev/raw/raw2

[root@vrh3 rules.d]#

[root@vrh3 rules.d]# ll /dev/asm*

brw-rw---- 1 oracle oinstall 8, 32 Jul 29 20:39 /dev/asm-diskc

brw-rw---- 1 oracle oinstall 8, 48 Jul 29 20:39 /dev/asm-diskd

brw-rw---- 1 oracle oinstall 8, 64 Jul 29 20:39 /dev/asm-diske

5.vrh2與vrh3 sshd互信配置

The key fingerprint is:

29:3b:dc:1b:49:bb:0e:90:29:a7:d6:6b:26:99:de:b7 oracle@vrh3.oracle.com

5.3 創建一個授權文件保存兩臺主機的授權信息

[oracle@vrh2 .ssh]$ touch authorized_keys

[oracle@vrh2 .ssh]$ cat id_dsa.pub  >> authorized_keys                #將本機vrh2上的dsa保存到授權文件中

[oracle@vrh2 .ssh]$ cat id_rsa.pub  >> authorized_keys                #將本機vrh2上的rsa保存到授權文件中

[oracle@vrh2 .ssh]$ ssh vrh3 cat ~/.ssh/id_dsa.pub >> authorized_keys #將vrh3上的dsa保存到授權文件中

The authenticity of host 'vrh3 (192.168.1.103)' can't be established. #將vrh3上的rsa保存到授權文件中

RSA key fingerprint is 92:e1:fc:a6:f8:15:37:27:7b:50:41:fa:be:4d:19:0b.

Are you sure you want to continue connecting (yes/no)? yes

Warning: Permanently added 'vrh3,192.168.1.103' (RSA) to the list of known hosts.
