Is this output of mounted.ocfs2 -f right?

Hi,
I'm wondering if my output of mounted.ocfs2 -f is right. I have 8 servers and 1 VM Master, each server has 1-3 disks for the shared storage, using extended iscsi storage. I am wondering, don't all the servers need to be listed in "Nodes" with this command?
[root@VMS01 ~]# mounted.ocfs2 -f
Device FS Nodes
/dev/sda3 ocfs2 Not mounted
/dev/sdb ocfs2 VMS01.a.be
/dev/sdc ocfs2 VMS01.a.be

When I add a second server to the pool I get this as output:

Along with all sorts of errors:
o2hb_do_disk_heartbeat: 781 ERROR: Device "sdc": another node is heartbeating in our slot!
After 10 minutes of those errors the master pool server reboots automatically due to those errors.

Ok so I set the time of all te servers but I still get the error:
o2hb_do_disk_heartbeat: 781 ERROR: Device "sdc": another node is heartbeating in our slot!
Does anyone have a suggestion what the problem could be? I get this error at creating server pool

I don't have access to the virtual machines at the moment so I'll send you the "fdisk -l" output later but here is the excerpt from Vincent Chan's Guide that I am following to configure ocfs2 oartition - my apologies that it is not formatted/readable because I have copied it from the PDF and pasted it:
6. Configure Oracle Cluster File System (OCFS2)
OCFS2 is a general-purpose cluster file system developed by Oracle and integrated with the
Enterprise Linux kernel. It enables all nodes to share files concurrently on the cluster file system and
thus eliminates the need to manage raw devices. Here you will house the OCR and Voting Disk in
the OCFS2 file system. Additional information on OCFS2 can be obtained from OCFS2 User’s
Guide.
You should already have the OCFS2 RPMs installed during the Enterprise Linux installation. Verify
that the RPMs have been installed on both nodes.
rac1-> rpm -qa | grep ocfs
ocfs2-tools-1.2.2-2
ocfs2console-1.2.2-2
ocfs2-2.6.9-42.0.0.0.1.ELsmp-1.2.3-2
Create the OCFS2 configuration file. As the root user on rac1, execute
# ocfs2console
OCFS2 Console: Select Cluster, 1. Configure Nodes.
2. “The cluster stack has been started”: Click on Close.
3. Node Configuration: Click on Add.
Add Node: Add the following nodes and then click on Apply.
Name: rac1
IP Address: 192.168.2.131
IP Port: 7777
Name: rac2
IP Address: 192.168.2.132
4.
Install Oracle RAC 10g on Oracle Enterprise Linux Using VMware Server http://www.oracle.com/technology/pub/articles/chan-ubl-vmware.html?...
20 of 42 11-1-2007 7:40
IP Port: 7777
Verify the generated configuration file.
# more /etc/ocfs2/cluster.conf
node:
ip_port = 7777
ip_address = 192.168.2.131
number = 0
name = rac1
cluster = ocfs2
node:
ip_port = 7777
ip_address = 192.168.2.132
number = 1
name = rac2
cluster = ocfs2
cluster:
node_count = 2
name = ocfs2
5.
Propagate the configuration file to rac2. You can rerun the steps above on rac2 to generate the
configuration file or select Cluster, Propagate Configuration on the OCFS2 Console on rac1
to propagate the configuration file to rac2.
6.
Configure the O2CB driver. O2CB is a set of clustering services that manages the communication
between the nodes and the cluster file system. Below is a description of the individual services:
NM: Node Manager that keep track of all the nodes in the cluster.conf
HB: Heartbeat service that issues up/down notifications when nodes join or leave the cluster
TCP: Handles communication between the nodes
DLM: Distributed lock manager that keeps track of all locks, its owners, and status
CONFIGFS: User space driven configuration file system mounted at /config
DLMFS: User space interface to the kernel space DLM
Perform the procedure below on both nodes to configure O2CB to start on boot.
When prompted for a value for the heartbeat dead threshold, you have to specify a value higher than
7 to prevent the nodes from crashing due to the slow IDE disk drive. The heartbeat dead threshold is
a variable used to calculate the fence time.
Fence time (seconds) = (heartbeat dead threshold -1) * 2
A fence time of 120 seconds works well in our environment. The value of heartbeat dead threshold
should be the same on both nodes.
As the root user, execute
# /etc/init.d/o2cb unload
Stopping O2CB cluster ocfs2: OK
Unmounting ocfs2_dlmfs filesystem: OK
Unloading module "ocfs2_dlmfs": OK
Unmounting configfs filesystem: OK
Unloading module "configfs": OK
# /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

mounted.

Checking O2CB heartbeat: Not active
You are only required to format the file system on one node. As the root user on rac1, execute
# ocfs2console
OCFS2 Console: Select 1. Tasks, Format.
Format:
Available devices: /dev/sdb1
Volume label: oracle
Cluster size: Auto
Number of node slots: 4
Block size: Auto
2.
3. OCFS2 Console: CTRL-Q to quit.
Mount the file system. To mount the file system, execute the command below on both nodes.
# mount -t ocfs2 -o datavolume,nointr /dev/sdb1 /ocfs
To mount the file system on boot, add the following line in /etc/fstab on both nodes.
/etc/fstab
/dev/sdb1 /ocfs ocfs2 _netdev,datavolume,nointr 0 0
Create Oracle Clusterware directory. Create the directory in OCFS2 file system where the OCR
and Voting Disk will reside.
On rac1,
# mkdir /ocfs/clusterware
# chown -R oracle:dba /ocfs
You have completed the set up of OCFS2. Verify that you can read and write files on the shared
cluster file system from both nodes.

Did you get anwer for this error? I got same error. Thanks in advance.

Hello. I have a problem with OEL 6.5 and ocfs2. When I mount ocfs2 with mount -a command all ocfs2 partitions mount and work, but when I reboot no ocfs2 partitions auto mount. No error messages in log. I use DAS FC and iSCSI FC.

When I mount ocfs2 with mount -a command all ocfs2 partitions mount and work, but when I reboot no ocfs2 partitions auto mount. No error messages in log. I use DAS FC and iSCSI FC.
fstab:

What is the output of:
# chkconfig --list o2cb
# chkconfig --list ocfs2
# cat /etc/ocfs2/cluster.conf

Can´t mount OCFS2 file system after Public IP modify

Guys,
We have an environment with 2 nodes with RAC database version 10.2.0.1. We need to modify the Public IP and VIP of the Oracle CRS. So we did the following steps:
- Alter the VIP
srvctl modify nodeapps -n node1 -A 192.168.1.101/255.255.255.0/eth0
srvctl modify nodeapps -n node2 -A 192.168.1.102/255.255.255.0/eth0
- Alter the Public IP
oifcfg delif -global eth0
oifcfg setif -global eth0/192.168.1.0:public
- Alter the IP´s of the network interfaces
- Update the /etc/hosts
When we start the Oracle CRS, the components starts OK. But when we reboot the second node, the OCFS2 file system didn´t mount. The following errors occurs:

ocfs2: Unmounting device (8,17) on (node 1)
When we did the command to force the mount occurs the errors:
# mount -a
mount.ocfs2: Transport endpoint is not connected while mounting /dev/sdb1 on /ocfs2. Check 'dmesg' for more information on this error.
What occurs is that the OCFS2 is trying to connect with the older Public IP. My question is, how do i change the public IP in the ocfs2 ?

Hi, is correct you maybe check the /etc/cluster.conf file, maybe the configuration is wrong, you can also check the /etc/hosts file for verify the correct definition host names.
Luck
Have a good day.

Hi Yuvaraj,
I am facing the same situation and the only difference is that I am abe to see ocfs2 mount point on rac1 node and in rac2 node, it is not viewable.
If you could send how to fix this issue, it will be very gr8ful and would appreciate your timely help.

Where does this output come from?

Since this morning I get the following message on my output console when I start my application, but I have no idea what triggers it.
I did determine that this class is responsible [ oracle.jbo.common.DebugDiagnostic ], but there's no source available for me to inspect. JDeveloper's help function (searched for "DebugDiagnostic" -- 1 topic) did not provide the right answer either.
It appears that this class is part of BC4J's debug output system, but I don't have logging enabled as far as I know. Other than this particular message, no other messages are displayed.
Can anyone provide some information regarding this matter? What does it mean? Why does it appear?
TIA

I have copied over my music file to a new computer and the music shows on itunes but wont play. When I track where the song is located it is reading the wrong information. How do I change this as Edit Preferences has the right location

I have copied over my music files to a new computer and the music shows on itunes but wont play. When I track where the song is located it is reading the wrong information. How do I change this as Edit>Preferences has the right location?

Select one of the tracks with a broken link, press ctrl-i to Get Info. Say No when iTunes asks if you would like to locate the track, then look at the Summary tab for the location expects to find the file in.
Now try to locate the file in question. The two locations should give a clue as to what to do next.
Here is an example with a file I've deliberately moved from the new layout to the old pre-iTunes 9 layout.
This means iTunes is expecting to find the file at:
D:\iTunes\iTunes Media\Music\a-ha\Take On Me\01 Take On Me.mp3
but it isn't there because I've moved it to:
D:\iTunes\iTunes Media\a-ha\Take On Me\01 Take On Me.mp3
which is where it would have lived back in iTunes 8 (though the media folder would have been called iTunes Music back then as well).
If you can provide the expected and actual locations of a broken track I should be able to suggest the easiest way to resolve things.

Why am I not able to export NEF files to Photoshop from Lightroom to edit. This is new. When I right click on an image, the export to PS option is not selectable.

Why am I not able to export NEF files to Photoshop from Lightroom to edit. This is new. When I right click on an image, the export to PS option is not selectable. I've never had this happen before. I haven't used it for a few weeks, so maybe there's an update (Mac or otherwise) that's screwing things up? HELP!

I have an Edit In - Photoshop option, but not an Export - Photoshop option.
Obviously to have right-click Edit In to work, the photo you're right-clicking on needs to be selected. I assume this is not the problem, and that the photo is selected.
Mavericks 10.9.3 has a problem where the Users folder is hidden, and you need to update iTunes to fix it, but it's been a few weeks since this happened so hopefully you're up-to-date and the Users folder isn't hidden anymore.
If you can't get things to work, I'd uninstall LR and uninstall Photoshop, then install Photoshop, and update it, then install LR and update it, as a way to get any wayward security or other OS-level things reset.

How to take this output from javacreator?

i wanna take this output.

... What? Can you word that into a somewhat sensible English sentence? Are you trying to create that output? I assume javacreator = JCreator? Anyways... I would suggest starting with a for loop nested within another for loop. That would be your best bet in terms of difficulty to implement.
Hint: first for loop would be your max number, going down, nested loop should be for printing each line.

Is this output of mounted.ocfs2 -f right?
