Cannot configure Oracle Cluster File System (OCFS2)

Dears,,
While trying to use ocfs2console to Configure Oracle Cluster File System (OCFS2)
Error appear to me as following:
Could not start cluster stack error.This must be resolved before any OCFS2 filesystem can be mounted.
How can solve this please?
thanks & regards,,

Dear all ,,
My issue solved now . . .
Really , it is strange.
Once , i added /sbin in .bash_profile under ~ Directory as following . . .
export PATH=$ORACLE_HOME/bin:$ORA_CRS_HOME/bin:/bin:/usr/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11R6/bin
Then log out then back again.
After this change , i able to run ocfs2console successfully.
Hope this help you.
Thanks for all,,
Best regards,,

Is OCFS(Oracle Cluster File System) a real file system?

Hi all
Is oracle cluster file system something kind of FAT23 or NTFS on Windows, ext3 on Linux ?
We install operating systems on FS , but with OCFS we install Oracle database on it instead of operation system ?
As usual
Applications
OS
File System
Physical Drive
But the ocfs is something like:
Oracle
OCFS
OS
OS's file system
Physical Drive
Is that right ?

OCFS is a clustered filesystem. You don't use it for OS partitions (e.g /opt) but only for filesystems that will be shared between servers in a RAC cluster to hold database files.
Are you installing RAC ? If so, then ASM is a better option than OCFS. If not, then you really don't need OCFS.Thanks
I'm studying RAC.
I hear that I can not put all kind of files into ASM but with OCFS I can hold them.
Is that improved with 11g R2 ?

Oracle cluster file system

dear all,
can someone please tell me where i can download ocfs or ocfs2 file system for windows OS..
Thank you in advance

There is no such thing as OCFS V2 for Windows
There is an OCFS for Windows, it is included (and installed) as part of the Oracle Clusterware. So if you download Oracle Clusterware for Windows and install it you will get an option to create an OCFS volume

Cluster file system

i have 2 cluster nodes (SuSE Linux Enterprise server 9) with shared storage, i will install some applications on this storage(oracle is NOT one of these applications),
is the oracle cluster file system is suitable to use for this case?

only the ocfs2, and this is it first prodcution version, so it will be better for you to wait
for the next versions.

Does /sapmnt need in cluster file system(SAP ECC 6.0 with oracle RAC)

We are going to be installing SAP with Oracle 10.2.0.4 RAC on Linux SuSE 10 and OCFS2. The Oracle RAC documentation states:
You must store the following components in the cluster file system when you use RAC
in the SAP environment:
- Oracle Clusterware (CRS) Home
- Oracle RDBMS Home
- SAP Home (also /sapmnt)
- Voting Disks
- OCR
- Database
What I want to ask is if I really need put SAP Home(also /sapmnt) on cluster file system? I will build a two nodes oracel 10g RAC and I also have another two nodes to install SAP CI and DI. My orginial think is sapmnt is a NFS share, and mount to all four nodes(RAC node and CI/DI), and all oracle stuff was on OCFS2(only two rac nodes are OCFS), anybody can tell me if SAP Home(also /sapmnt) can be NFS mount not OCFS2, thanks.
Best regards,
Peter

Hi Peter,
I don't think you need to keep /sapmnt in ocfs2 . Reason any file system need to be in cluster is,in RAC environment, data stored in the cache of one Oracle instance to be accessed by any other instance by transferring it across the private network and preserves data integrity and cache coherency by transmitting locking and other synchronization information across cluster nodes.
AS this applies to redo files, datafiles and control files only , you should be fine with nfs mount of /sapmnt sharing across and not having ocfs2.

Advantages of Oracle ASM Cluster File Systems (ACFS)

Hi
configured 11g Rel 2 Grid Infr , ASM instance and the database on linux x86_64 bit
when I started asmca, i noticed that there are no volumes configured
Need to know what are the advantages of configuring volumes,
[root@vmorarac2 init.d]# lsmod

Oracle Text/Oracle Internet File System Installation/Configuration

Hi,
I have installed Oracle9i Database v9.0.1.0.0 on Linux. I would like to install Oracle 9i Internet File System as well. In the Oracle Internet File System pre-installation process, the pre-requisite for installing this is Oracle Text ( but optional ). How do I know that Oracle Text has been installed in the Oracle Universal Installer? If Oracle Text is installed, what is the best way to find out, it is configured properly?
Why am I asking this is, when I install Oracle Internet File System, I'm getting an error
"Unable to verify Oracle Text configuration. The following error occured:
oracle.ifs.utils.action.ActionFailedException : Oracle Text seems to be misconfigured".
Please help.
Thanks
Sriram

I think the problem is your database configuration.
You can reconfigure your database, it will hellp your database
have Oracle Text .
Before that, you need use Universal Installer, In Installed Products Tree, sure that you see
Oracle Text in the Oracle Database 9i node.

Raw devices versus Cluster File Systems in RAC 10gR2

Hi,
Does anyone using cluster file systems in a RAC 10gR2 installation, specifically IBMs GPFS?
Ive visited a company that is running RAC 10gR2 in AIX over raw devices. Why someone would choose to use raw devices , with all the problems to administer , when all the modern file systems are so powerful? Is there any issues when using cluster file systems + RAC? Is there considerable performance benefits when using raw devices with RAC ?
I´ve always used Oracle stand alone instances over file systems (since version 7) , and performance was always very good. I´ve tested raw devices almost 10 years ago , and even in that time (the hardware today is much better - SAN , 15K rpm disks , huge caches - and the file systems software today is much better) the cost to administer it does not compensate the benefits (only 5% more faster than file systems in Oracle 7).
So , besides any limitations imposed by RAC , why use raw devices nowadays ?
Regards,
Antonio Belloni

Hi,
spontaneously, my question would be: How did you eliminate the influence of the Linux File System Cache on ext3? OCFS2 is accessed with the o_direct flag - there will be no caching. The same holds true for RAW devices. This could have an influence on your test and I did not see a configuration step to avoid it.
What I saw, though, is "counter test": "I have tried comparing simple file copies from an OS level and the speed differences are not apparent - so the issue only manifests itself when the data is read via an oracle db." and I have no good answer to that one.
Maybe this paper has: http://www.oracle.com/technology/tech/linux/pdf/Linux-FS-Performance-Comparison.pdf - it's a bit older, but explains some of the interdependencies.
Last question: While you spent a lot of effort on proving that this one query is slower on OCFS2 or RAW than on ext3 for the initial read (that's why you flushed the buffer cache before each run), how realistic is this scenario when this system goes into production? I mean, how many times will this query be read completely from disk as opposed to use some block from the buffer? If you consider that, what impact does the "IO read time from disk" have on the overall performance of the system? If you do not isolate the test to just a read, how do writes compare?
Just some questions. Thanks.

Best Practice for Distributed TREX NFS vs cluster file systems

Hi,
We are planning to implement a distributed TREX, using RedHat on X64, but we are wondering which could be the best practice or approach to configure the "file server" used on the TREX distributed environment. The guides mention file server, that seems to be another server connected to a SAN exporting or sharing the file systems required to be mounted in all the TREX systems (Master, Backup and Slaves), but we know that the BI accelerator uses OCFS2 (cluster file systems) to access the storage, in the case of RedHat we have GFS or even OCFS.
Basically we would like to know which is the best practice and how other companies are doing it, for a TREX distributed environment using either network file systems or cluster file systems.
Thanks in advance,
Zareh

I would like to add one more thing, in my previous comment I assumed that it is possible to use cluster file system on TREX because BI accelerator, but maybe that is not supported, it does not seem to be clear on the TREX guides.
That should be the initial question:
Aare cluster file system solutions supported on plain TREX implementation?
Thanks again,
Zareh

Linux Cluster File System partitions for 10g RAC

Hi Friends,
I planned to install 2 Node Oracle 10g RAC on RHEL and I planned to use Linux File system itself for OCR,Voting Disk and datafiles (no OCFS2/RAW/ASM)
I am having SAN storage.
I would like to know how do i create shared/cluster partitions for OCR,Voting Disk and Datafiles (common storage on SAN).
Do i need to install any Linux cluster file system for creating these shared partitions (as we have sun cluster in solaris)?
If so let me know what versions are supported and provide the necessary Note / Link
Regards,
DB

Hi ,

Oracle´s File system over GPFS on Oracle RAC

Hi all,
I would like to know which Oracle´s File systems should be over GPFS on a Oracle RAC implementation.
Regards,
Sebastian.

You didn't provide info about DB relase and OS.
But probably you are talking about AIX OS (I can't see any reason to use GPFS on Linux for RAC and I don't remember if this FS was/is supported for RAC on Linux (check Certification Matrix for this information)). Oracle is provides only one shared "filesystem" for AIX and it is ASM.
Now it depends on DB version what options you can use.
Till 11g R2 you have to store OCR and Voting disks outside of ASM (So you needed to use either RAW devices or Cluster Filesystem which GPFS is). Since 11g R2 you can store these disks in ASM directly.
On Linux if you don't want to use ASM to store database files you can use OCFS2 clusterfile system.

IS RAW DEVICES SUPPORTED OVER A CLUSTER FILE SYSTEM

Can raw partions be defined for datafiles after having choosen Cluster file system as storage option for database while creating fresh database using
DBCA?

> Do update on how the partitions have to be defined in either cases?
For both ASM and OCFS, a partition must exist on the disk - it can be of any partition type. Does not matter. Simply that the s/w references a partition and not an entire disk.
So for example, /dev/sdaf and dev/sdag are two shared devices on the cluster (LUNs on the SAN or whatever).
You create a partition on each. E.g
# fdisk -l /dev/sdaf
Disk /dev/sdaf: 36.5 GB, 36573020160 bytes
255 heads, 63 sectors/track, 4446 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sdaf1 1 4446 35712463+ 83 LinuxTo use the first device as a OCFS device, you need to build an ocfs file system on it using mkfs.
And then it can be mounted as a "normal" cooked file system mount. Remember that /etc/fstab needs to be updated for mounting it on startup.
To use the second device for ASM, you have two choices. If you have the ASMlib kernel module installed, you can use that to configure a volume label and assign it for use by ASM.
Alternatively, you simply map the device (partition) to a raw device for detection by ASM. E.g.
# raw /dev/raw/raw1 /dev/sdag1Of course, you also need to make this permanent by updating the raw device list config file so that this mapping is performed on reboot. On Linux, this is the /etc/sysconfig/rawdevices file. Also remember that the user and group access for the logical raw device created, must allow ASM full access to it (e.g. use chmod oracle.dba /dev/raw/raw1).
In a nutshell, this is how to raw devices are used as ocfs and asm volumes. (on RHEL specifically, but I expect no major differences in this approach on other o/s's)

Asmca has grayed out Volumes and ASM Cluster File Systems 11.2.0.3

I've got a two node cluster which is up and running with the latest 11.2.0.3 grid install on Oracle Linux 6.3
I need to get a shared storage location I can use for File I/O testing, ASM looks like the solution with an ASM Cluster File System.
When I run asmca I do not have the ability to create these volumes or file systems as they are Grayed out.
I found some instructions on how to get it to work, and they said to use acfsload to start up the required daemons:
[root@oracleA bin]# ./acfsload start -s
ACFS-9459: ADVM/ACFS is not supported on this OS version: '2.6.39-300.17.3.el6uek.x86_64'
I installed Patches: 13146560, 14596051 - Which I thought would fix the problem. Rebooted after successfully applying the patches, but asmca still shows them greyed out
and not supported on this OS error persists.
I see some posts online saying to edit osds_acfslib.pm and update it to allow for the supported ORACLE version
Right now it shows: ($release =~ /^oraclelinux-release/))) # Oracle Linux
under /etc it only has oracle-release - could that have something to do with it not passing the check?
uname -r
2.6.39-300.17.3.el6uek.x86_64
From what I can tell this kernal should support asm..
Any help in getting these shared storage asm disks setup would be very helpful, oracleasm creates them and sees them fine for databases. Thanks.

Turns out the Kernel version 2.6.39 does not have support for the ASM Drivers for the ACFS mounting.
I'm going to have to use Oracle Linux 6.2 (instead of Oracle Linux 6.3) and rebuild my RAC to get a supported version of the drivers -> Kernel version 2.6.32

Sun QFS cluster file system with Veritas Volume Manager

Hi,
Can someone confirm whether it is possible to create a Sun QFS cluster file system (for Oracle RAC datafiles) using a VxVM volume?
Or must we use Solaris Volume Manager with QFS?
Thinking of storing the static part of the Oracle RAC DB on VxVM raw devices, and the dynamic part on a QFS file system to avoid the overhead of constantly adding new raw devices when i want to create datafiles.
Thanks,
Steve

Steve,
No, shared QFS is only supported on Solaris Volume Manager. I've not heard of any plans to test it on VxVM.
Why not keep the static parts of the DB on raw SVM devices? Why keep them on raw devices at all?
