ocfs2檔案系統問題總結(zt)

1: Starting O2CB cluster ocfs2: Failed

在安裝完ocfs2 後,配置o2cb 出錯:
[root@rac1 ocfs2]# /etc/init.d/o2cb configure
Configuring the O2CB driver.

This will configure the on-boot properties of the O2CB driver.
The following questions will determine whether the driver is loaded on
boot. The current values will be shown in brackets ('[]'). Hitting
without typing an answer will keep that current value. Ctrl-C
will abort.

Load O2CB driver on boot (y/n) [y]:
Cluster to start on boot (Enter "none" to clear) [ocfs2]:
Specify heartbeat dead threshold (>=7) [7]:
Writing O2CB configuration: OK
Starting O2CB cluster ocfs2: Failed
Cluster ocfs2 created
     o2cb_ctl: Configuration error discovered while populating cluster ocfs2. None of its nodes were considered local. A node is considered local when its node name in the configuration matches this machine's host name.
Stopping O2CB cluster ocfs2: OK

出現這中情況,應該是OCFS沒有配置，可以看一下，有一個圖形ocfs配置命令，首先要配置他，而且最好 用IP地址，不要用主機名！

也就是說,在啟動ocfs2時,ocfs節點配置檔案一定要配置好,如果沒有配置正確,就會報錯,同時在用圖形介面配置的時候,/etc/ocfs2/cluster.conf檔案最好是空檔案,要不然也會報錯!

2: mount.ocfs2: Error when attempting to run /sbin/ocfs2_hb_ctl: "Operation not permitted"

mount -t ocfs2 -o datavolume /dev/sdb1 /u02/oradata/orcl
ocfs2_hb_ctl: Bad magic number in superblock while reading uuid
mount.ocfs2: Error when attempting to run /sbin/ocfs2_hb_ctl: "Operation not permitted"

ocfs2檔案檔案系統分割槽沒有格式化引起的錯誤,在掛載ocfs2檔案系統之前,用於這個檔案系統的分割槽一定要進行格式化.

掛載ocfs2檔案系統
mount -t ocfs2 -o datavolume /dev/sdc1 /u02/oradata/orcl
報如下錯誤:
ocfs2_hb_ctl: Unable to access cluster service while starting heartbeat
mount.ocfs2: Error when attempting to run /sbin/ocfs2_hb_ctl: "Operation not permitted"

3: Configuration assistant "Oracle Cluster Verification Utility" failed

10g rac 安裝請教　oracle 10.2.0.1 solaris 5.9 雙機　安裝ｃｒｓ最後一步有錯，不知如何解決？

是不是vip地址沒有啟動造成的，建議在執行完orainstRoot.sh和root.sh命令後新開個視窗執行vipca，把crs服務都起來後再執行最後的verify步驟，可以嘗試一下。去crs的bin目錄下執行crs_stat -t 看看服務是不是都起了，我也覺得是vip沒起來

4: Failed to upgrade Oracle Cluster Registry configuration

在安裝CRS時,在第二個節點執行./root.sh時,出現如下提示,我在第一個節點執行正常.請大蝦指點一些,不勝感激!謝謝!
[root@RACtest2 crs]# ./root.sh
WARNING: directory '/app/oracle/product/10.2.0' is not owned by root

PROT-1: Failed to initialize ocrconfig
Failed to upgrade Oracle Cluster Registry configuration

錯誤原因:是因為安裝crs的裝置許可權有問題,例如我的裝置用raw來放置ocr和vote,此時要設定好這些硬體裝置以及連線的檔案的許可權,下面是我的環境:

[root@rac2 oracrs]#

lrwxrwxrwx  1 root root 13 Jan 27 12:49 ocr.crs -> /dev/raw/raw1

lrwxrwxrwx  1 root root 13 Jan 26 13:31 vote.crs -> /dev/raw/raw2

chown root:oinstall /dev/raw/raw1

chown root:oinstall /dev/raw/raw2

chmod 660 /dev/raw/raw1

chmod 660 /dev/raw/raw2

其中/dev/sdb1放置ocr,/dev/sdb2放置vote.

[root@rac2 oracrs]# service rawdevices reload

Assigning devices:

           /dev/raw/raw1  --&gt   /dev/sdb1

/dev/raw/raw1:  bound to major 8, minor 17

           /dev/raw/raw2  --&gt   /dev/sdb2

/dev/raw/raw2:  bound to major 8, minor 18

Done

然後再次執行就ok了.

在安裝的a節點上執行root.sh如下：

首先檢查防火牆是否關閉:

檢查並關閉 UDP ICMP 拒絕

在 Linux 安裝期間，我指出不配置防火牆選項。預設情況下，配置防火牆的選項由安裝程式選擇。這使我吃了好幾次苦頭，因此我要仔細檢查防火牆選項是否未配置，並確保 udp ICMP 過濾已關閉。

如果 UDP ICMP 被防火牆阻塞或拒絕，Oracle 叢集件軟體將在執行幾分鐘之後崩潰。如果 Oracle 叢集件程式出現故障，您的 _evmocr.log 檔案中將出現以下類似內容：

08/29/2005 22:17:19
　oac_init:2: Could not connect to server, clsc retcode = 9
　08/29/2005 22:17:19
　a_init:12!: Client init unsuccessful : [32]
　ibctx:1:ERROR: INVALID FORMAT
　proprinit:problem reading the bootblock or superbloc 22
　如果遇到此類錯誤，解決方法是移除 udp ICMP (iptables) 拒絕規則，或者只需關閉防火牆選項。之後，Oracle 叢集件軟體將開始正常工作，而不會崩潰。以下命令應該以 root 使用者帳戶的身份執行：

1.            檢查以確保防火牆選項關閉。如果防火牆選項已停用（如下面的示例所示），則不必繼續執行以下步驟。
# /etc/rc.d/init.d/iptables statusFirewall is stopped

2.            如果防火牆選項已啟用，您首先需要手動停用 UDP ICMP 拒絕：
# /etc/rc.d/init.d/iptables stopFlushing firewall rules: [ OK ]Setting chains to policy ACCEPT: filter [ OK ]Unloading iptables modules: [ OK ]

3.            然後，針對下一次伺服器重啟關閉 UDP ICMP 拒絕（應該始終被關閉）：
# chkconfig iptables off

再次,如果不是上面的問題,

建議你先用dd把ocr和votedisk清除資訊，再給許可權，再執行 root.sh
給你看看我的第一個節點執行root.sh的反饋資訊:

6: CRS-0215: Could not start resource 'ora.orcl.orcl1.inst'.

$ srvctl start instance -d orcl -i orcl1
PRKP-1001 : 在節點 znawdb1 上啟動例項 orcl1 時出錯
CRS-0215: Could not start resource 'ora.orcl.orcl1.inst'.

出現這個問題的原因是因為裝載資料庫資料檔案的ocfs2檔案系統,或者是ASM例項沒有掛載的原因,例如,我的環境是raw+ASM,當沒有掛載ASM例項,然後用srvctl start asm –n rac1啟動了ASM,但是這個啟
