Ocfs2文件系統(tǒng)常見問題解決方法1

現(xiàn)象一：
mount -t ocfs2 -o datavolume,nointr /dev/sdb1 /webdata
mount.ocfs2: Transport endpoint is not connected while mounting /dev/sdb1 on /webdata. Check 'dmesg' for more information on this error.

可能問題：
1：防火墻打開著，沒有關(guān)閉，屏蔽了心跳端口
2：各個節(jié)點的/etc/init.d/o2cb configure值配置不同導致。
3：一個節(jié)點處于掛載中，另外一個節(jié)點剛剛配置好，重啟了ocfs2服務導致，此時只要把連個節(jié)點都重啟一下服務即可完成掛載。

4：SElinux沒有關(guān)閉導致。

下面是一個案例：

[root@test02 ~]# mount -t ocfs2 /dev/vg_ocfs/lv_u02 /u02
mount.ocfs2: Transport endpoint is not connected while mounting /dev/vg_ocfs/lv_u02 on /u02. Check 'dmesg' for more information on this error.
出現(xiàn)這個錯誤是由于配置OCFS時O2CB_HEARTBEAT_THRESHOLD各節(jié)點的值不一樣導致的。我用/etc/init.d/o2cb configure時其實各個節(jié)點的值已經(jīng)都一樣了，不過第一個節(jié)點忘了重啟o2cb，結(jié)果查了好久才發(fā)現(xiàn)。接下當然是把已經(jīng)MOUNT的OCFS目錄UMOUNT掉，結(jié)果又出錯了：
[root@test01 u02]# umount -f /u02
umount2: Device or resource busy
umount: /u02: device is busy
umount2: Device or resource busy
umount: /u02: device is busy
這時候應該用/etc/init.d/ocfs2 stop和/etc/init.d/o2cb stop停掉OCFS2和O2CB再UMOUJNT才行，然后把OCFS2和O2CB啟動以后其他節(jié)點就可以順利MOUNT OCFS了。
現(xiàn)象二：
# /etc/init.d/o2cb online ocfs2

Starting 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 maches this machine's host name.

Stopping cluster ocfs2: OK

主機名問題，檢查more /etc/ocfs2/cluster.conf以及/etc/hosts文件信息，修改相應的主機名即可

注意：為了保證開機能自動掛載ocfs2文件系統(tǒng)，需要在/etc/fstab加入自動啟動選項后，必須在/etc/hosts中加入兩個節(jié)點的主機名和ip的對應解析，主機名和 /etc/ocfs2/cluster.conf配置的主機名一定要相同。

現(xiàn)象三

1: Starting O2CB cluster ocfs2: Failed
在安裝完ocfs2 后,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
<ENTER> 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(xiàn)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(jié)點配置文件一定要配置好,如果沒有配置正確,就會報錯,同時在用圖形界面配置的時候,/etc/ocfs2/cluster.conf文件最好是空文件,要不然也會報錯!
現(xiàn)象四
掛載ocfs2文件系統(tǒng)遇到
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"
這個問題是由于ocfs2文件文件系統(tǒng)分區(qū)沒有格式化引起的錯誤,在掛載ocfs2文件系統(tǒng)之前,用于這個文件系統(tǒng)的分區(qū)一定要進行格式化.
現(xiàn)象五：
Configuration assistant "Oracle Cluster Verification Utility" failed

是vip地址沒有啟動造成的，建議在執(zhí)行完orainstRoot.sh和root.sh命令后新開個窗口執(zhí)行vipca，把crs服務都起來后再執(zhí)行最后的verify步驟，可以嘗試一下。

去crs的bin目錄下執(zhí)行crs_stat -t 看看服務是不是都起了，這種情況應該是vip沒起來。
現(xiàn)象六：
Failed to upgrade Oracle Cluster Registry configuration
在安裝CRS時,在第二個節(jié)點執(zhí)行./root.sh時,出現(xiàn)如下提示,我在第一個節(jié)點執(zhí)行正常.請大蝦指點一些,不勝感激!謝謝!
[root@RACtest2 crs]# ./root.sh

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

是因為安裝crs的設備權(quán)限有問題,例如我的設備用raw來放置ocr和vote,此時要設置好這些硬件設備以及連接的文件的權(quán)限,下面是我的環(huán)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

           /dev/raw/raw1 -->   /dev/sdb1
/dev/raw/raw1: bound to major 8, minor 17
           /dev/raw/raw2 -->   /dev/sdb2
/dev/raw/raw2: bound to major 8, minor 18
Done

然后再次執(zhí)行就ok了.
