Ocfs2文件系统常见问题解决方法

现象一：
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.

可能问题：

1：防火墙打开着，没有关闭，屏蔽了心跳端口

2：各个节点的/etc/init.d/o2cb configure值配置不同导致。

IXDBA.NET社区论坛

3：一个节点处于挂载中，另外一个节点刚刚配置好，重启了ocfs2服务导致，此时只要把连个节点都重启一下服务即可完成挂载。

4：SElinux没有关闭导致。

下面是一个案例：

[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.

出现这个错误是由于配置OCFS时O2CB_HEARTBEAT_THRESHOLD各节点的值不一样导致的。我用/etc/init.d/o2cb configure时其实各个节点的值已经都一样了，不过第一个节点忘了重启o2cb，结果查了好久才发现。接下当然是把已经MOUNT的OCFS目录UMOUNT掉，结果又出错了：

[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

这时候应该用/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启动以后其他节点就可以顺利MOUNT OCFS了。

现象二：
# /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

主机名问题，检查more /etc/ocfs2/cluster.conf以及/etc/hosts文件信息，修改相应的主机名即可

注意：为了保证开机能自动挂载ocfs2文件系统，需要在/etc/fstab加入自动启动选项后，必须在/etc/hosts中加入两个节点的主机名和ip的对应解析，主机名和 /etc/ocfs2/cluster.conf配置的主机名一定要相同。

现象三

1: Starting O2CB cluster ocfs2: Failed
在安装完ocfs2 后,配置o2cb 出错:
[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

出现这中情况,应该是OCFS没有配置，可以看一下，有一个图形ocfs配置命令，首先要配置他，而且最好用IP地址，不要用主机名！

也就是说,在启动ocfs2时,ocfs节点配置文件一定要配置好,如果没有配置正确,就会报错,同时在用图形界面配置的时候,/etc/ocfs2/cluster.conf文件最好是空文件,要不然也会报错!

现象四
挂载ocfs2文件系统遇到
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"

这个问题是由于ocfs2文件文件系统分区没有格式化引起的错误,在挂载ocfs2文件系统之前,用于这个文件系统的分区一定要进行格式化.

现象五：

是vip地址没有启动造成的，建议在执行完orainstRoot.sh和root.sh命令后新开个窗口执行vipca，把crs服务都起来后再执行最后的verify步骤，可以尝试一下。

去crs的bin目录下执行crs_stat -t 看看服务是不是都起了，这种情况应该是vip没起来。

现象六：
Failed to upgrade Oracle Cluster Registry configuration
在安装CRS时,在第二个节点执行./root.sh时,出现如下提示,我在第一个节点执行正常.请大虾指点一些,不胜感激!谢谢!
[root@RACtest2 crs]# ./root.sh

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

错误原因:

是因为安装crs的设备权限有问题,例如我的设备用raw来放置ocr和vote,此时要设置好这些硬件设备以及连接的文件的权限,下面是我的环境:

[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 --> /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

然后再次执行就ok了.

首先检查防火墙是否关闭:

检查并关闭 UDP ICMP 拒绝

在 Linux 安装期间，我指出不配置防火墙选项。默认情况下，配置防火墙的选项由安装程序选择。这使我吃了好几次苦头，因此我要仔细检查防火墙选项是否未配置，并确保 udp ICMP 过滤已关闭。

如果 UDP ICMP 被防火墙阻塞或拒绝，Oracle 集群件软件将在运行几分钟之后崩溃。如果 Oracle 集群进程出现故障，您的 <machine_name>_evmocr.log 文件中将出现以下类似内容：

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

　如果遇到此类错误，解决方法是移除 udp ICMP (iptables) 拒绝规则，或者只需关闭防火墙选项。之后，Oracle 集群件软件将开始正常工作，而不会崩溃。以下命令应该以 root 用户帐户的身份执行：

1. 检查以确保防火墙选项关闭。如果防火墙选项已停用（如下面的示例所示），则不必继续执行以下步骤。
# /etc/rc.d/init.d/iptables statusFirewall is stopped
.

2. 如果防火墙选项已启用，您首先需要手动停用 UDP ICMP 拒绝：
# /etc/rc.d/init.d/iptables stopFlushing firewall rules: [ OK ]Setting chains to policy ACCEPT: filter [ OK ]Unloading iptables modules: [ OK ]

3. 然后，针对下一次服务器重启关闭 UDP ICMP 拒绝（应该始终被关闭）：
# chkconfig iptables off

再次,如果不是上面的问题,

建议你先用dd把ocr和votedisk清除信息，再给权限，再运行 root.sh

看看我的第一个节点运行root.sh的反馈信息:

现象八：
CRS-0215: Could not start resource 'ora.orcl.orcl1.inst'.
$ srvctl start instance -d orcl -i orcl1
PRKP-1001 : 在节点 znawdb1 上启动实例 orcl1 时出错
CRS-0215: Could not start resource 'ora.orcl.orcl1.inst'.

出现这个问题的原因是因为装载数据库数据文件的ocfs2文件系统,或者是ASM实例没有挂载的原因,例如,我的环境是raw+ASM,当没有挂载ASM实例,然后用srvctl start asm –n rac1启动了ASM,但是这个启动,并没有挂载ASM,因此当再次执行srvctl start instance -d orcl -i orcl1的时候,就出现了CRS-0215: Could not start resource 'ora.orcl.orcl2.inst'.

此时执行ALTER DISKGROUP dgroup1 MOUNT;后再次执行srvctl start instance -d orcl -i orcl1,启动成功.

现象九
CRS-0223: Resource 'ora.rac1.LISTENER_RAC1.lsnr' has placement error.
错误一般提示如下:

[oracle@rac1 admin]$ srvctl start nodeapps -n rac1
