RAC with OCFS2 shared storage

Hi all
I wont to create RAC env in oracle VM 2.2 (one server) , with lokal disk's which I used to create LVM for ocr in in guest:
- two quest with Oracle enterprise linux 5
- both have ocfs2 rpm instaled
when I wont to create shared storage for ocr I configure cluster.conf
- service o2cb configure -> all ok -> on both nodes
- service o2cb enable -> ok -> on both nodes
- then mkfs.ocfs2 in node1
- mount -t ocfs2 in node1
- mount -t ocfs2 in node 2:
[root@lin2 ~]# mount -t ocfs2 /dev/sde1 /ocr
mount.ocfs2: Transport endpoint is not connected while mounting /dev/sde1 on /ocr. Check 'dmesg' for more information on this error.

How to implement RAC with no shared storage available...

Hello Guys,
I have installed, configured single node RAC R2 with 2 database instances on windows 2000 platform with the help of vmware software. Installation was successfull.
I just meet my boss to explain him my acheivements and to get permission to go for prodcution environment where we will be developing 3 nodes RAC on linux platform.
I asked him that we need a shared stroage system that can be achieved by SAN or NAS or firewire disks... but he refuses to buy any additioan hardware as we have already spend a lot on servers. He wants to me have another computer with a large size Hard Disk Drive to be used as shared storage.
I just want to know can we configure 3 nodes RAC using HDD of an other computer as sommon shared storage...
Please guide me. I really want to implement RAC in our production environment.
Regards,
Imran

Yeah, but would openfiler work? Has any one
implemented RAC using open filer or software
configured shared storage.
Any other better solution as i have to implement it
in production environment and have to seek better
backup facilities.Are you looking for a production environment, or an evaluation environment?
For an evaluation environment OpenFiler works. I occasionally teach RAC classes using that. It works but it is not as fast or as robust as I'd like in production.
For a production environment, plan to pay some money. The least expensive commercial shared stored I have found is from NetApp - any NetApp F8xx or FAS2xx files with iSCSI or even NFS license will do for RAC.

crs is not started in any of the nodes. I would like to know if anybody faced this kind of a problem when using QFS on diskgroup. When one disk is failed, the oracle is not supposed to go offline as the other disk is working, and also my qfs configuration is to mirror these two disks !!!!!!!!!!!!!!
Many thanks in advance
Ushas Symon

I'm not sure why you say QFS is mirroring these disks!?!? Shared QFS has no inherent mirroring capability. It relies on the underlying volume manager (VM) or array to do that for it. If you need to mirror you storage, you do it at the VM level by creating a mirrored metadevice.

Root.sh hangs at formatting voting disk on OEL32 11gR2 RAC with ocfs2

Hi,
Am trying to bring up Oracle11gR2 RAC on Enterprise Linux x86 (32bit) version 5.6. I am using Ocfs2 1.4 as my cluster file share. Everything went fine till the root.sh and it hangs with a message "now formatting voting disk <vdsk path>

ITunes, with Maxtor Shared Storage.

Hi Guys,
I've set my iTunes Music Folder location to that of my Maxtor Shared Storage drive (where all my music is) but none of my music is displayed in iTunes? What am I missing here? I have a music folder plus lots of sub folders, I've tried doing a reset but no luck.
Need some help

gtiskin, Welcome to the discussion area!
Perhaps you should ask this in the iTunes discussion area or the Tiger (10.4) networking discussion area.

Hello Guys,
I was reading this article on link http://www.dizwell.com/prod/node/25 it says the following
"If you had a physical machine with two network cards installed and a second hard disk with absolutely nothing else on it, you could achieve a RAC using a physical machine"
I am in procesof installing 2 nodes RAC and have configure network requirements on each node. I am struck with shared disk storage... can i acheive a shared diak storage by adding an other hardrive to one of the nodes? Please help...

Creating VMs on single DL360 server with no shared storage

Hi,
I would like to create 3 VMs on a DL360 using internal disks only. I am using Oracle VM 3.0.2.
Before I start I was trying to understand the online docs -
Can someone give me the benefit of their experiance and tell me if my following assumptions are true?
1. I still need to create a server pool even though I will not be using any HA features.
2. One entire disk is needed for VM server installation - so I cannot use this disk as 'local storage' for the server pool.
Point 2 above I am not sure about... I would like to mirror the internal disks and I cannot afford to lose a full disk for the VM server installation.
Any help much appreciated!

2. One entire disk is needed for VM server installation - so I cannot use this disk as 'local storage' for the server pool.Correct. Any disk that is partitioned for the installation is not usable for server pool storage. You would need additional disks. If you wanted to mirror the internal disks, you would need to be able to present two mirrored logical disks to the operating system, if that's possible. I haven't played with a DL360, so I'm not sure what the onboard RAID controller is capable of.

how do i add another phone to my apple id without sharing storage

You can share purchases by using the same Apple ID in

You daughter should use her own Apple ID for all other Apple services (iMessage, FaceTime, Game Center, iCloud, etc...)

Oracle RAC with ASM install failure

Hi Guy's
I've just rebuilt an Oracle RAC system, i've built this system many times and have the build documented. I usually follow the build doc to the tee and everything works fine. I have now been asked to rebuild the system to go into the production evironment. This is a two server standard RAC setup using ASM. We have a HP MSA500 shared storage setup. I've run the cluster verification tool and all the checks have come out fine. Whilst installing the clusterware i get a failed error message whilst it try's to confiure the Oracle Clusterware Configuration Assistant.
The error message i get is:
Command = C:\Windows\system 32\cmd\C Call E:\Oracle\Product\10.2.0\crs\install\crssetup.config.bat
PROT-1:Failed to intialize OCR Config
STEP 1 Checking status of CRS cluster
STEP 2 Creating directories (E:\Oracle\Product\10.2.0\Crs
STEP 3 Configuring OCR repository
ocr upgrade failed with (-1)
I've done this build many times and never seen this error. From what i've read on the internet it looks like it could be something up with my shared storage but i dont know what.
Any help would be greatly appreciated
Thanks

How do i licence a two node RAC with ASM infrastructure

AM trying to estimate the licensing of two node RAC with ASM as storage manager and GRID control as management tool

Hi,
Oracle license depends on lot of things, Edition of Oracle your running standard or enterprise, the optional packges you need and etc.
Read through http://docs.oracle.com/cd/E11882_01/license.112/e10594/editions.htm#BABDJGGI
also if you license named users or processor. You can get the price for the from online oracle store

Problem of using OCFS2 as shared storage to install RAC 10g on VMware

Hi, all
I am installing a RAC 10g cluster with two linux nodes on VMware. I created a shared 5G disk for the two nodes as shared storage partition. By using OCFS2 tools, i formatted this shared storage partition and successfully auto mounted it on both nodes.
Before installing, i use the command "runcluvfy.sh stage -pre crsinst -n node1,node2" to determine the installation prerequisites. Everything is ok except an error "Could not find a suitable set of interfaces for VIPs.". By searching the web, i found this error could be safely ignored.
The OCFS2 works well on both nodes, i formatted the shared partition as ocfs2 file system and configure o2bc to auto start ocfs service. I mounted the shared disk on both nodes at /ocfs directory. By adding an entry into both nodes' /etc/fstab, this partition can be auto mounted at system boots. I could access files in shared partition on both nodes.
My problem is that, when installing clusterware, at the stage "Specify Oracle Cluster Registry", I enter "/ocfs/OCRFILE" for Specify OCR Location and "/ocfs/OCRFILE_Mirror" for Specify OCR Mirror Location. But got an error as following:
----- Error Message ----
The location /ocfs/OCRFILE, entered for the Oracle Cluster Registry(OCR) is not shared across all the nodes in the cluster. Specify a shared raw partition or cluster file system that is visible by the same name on all nodes of the cluster.
------ Error Message ---
I don't know why the OUI can't recognize /ocfs as shared partition. On both nodes, using command "mounted.ocfs2 -f", i can get the result:
Device FS Nodes
/dev/sdb1 ocfs2 node1, node2
What's the possible wrong? Any help is appreciated!
Addition information:
1) uname -r
2.6.9-42.0.0.0.1.EL
2) Permission of shared partition

Hello
I am not sure how far this following solution is relevant to your problem (regardless when it was originally posted - may help someone who is reading this thread), here is what I faced and here is how I fixed it:
I was setting up RAC using VMWare. I prepared rac1 [installed OS, configured disks, users, etc] and the made a copy of it as rac2. So far so good. When, as per the guide I was following for RAC configuration, I started OCFS2 configuration, faced the following error on RAC2 when I tried to mount the /dev/adb1:
===================================================
[Root @ *rac2* ~] # mount - t ocfs2 - o datavolume, nointr / dev / sdb1 / ocfs
ocfs2_hb_ctl: OCFS2 DIRECTORY corrupted WHILE reading uuid ocfs2_hb_ctl: OCFS2 DIRECTORY corrupted WHILE reading uuid
mount.ocfs2: Error WHEN attempting TO run / sbin / ocfs2_hb_ctl: "Operation not permitted" mount.ocfs2: Error WHEN attempting TO run / sbin / ocfs2_hb_ctl: "Operation not permitted"
===================================================
After a lot of "googling around", I finally bumped into a page, the kind person who posted the solution said [in my words below and more detailed ]:
o shutdown both rac1 and rac2
o in VMWare, "edit virtual machine settings" for rac1
o remove the disk [make sure you drop the correct one]
o recreate it and select *"allocate all disk space now"* [with same name and in the same directory where it was before]
o start rac1 and login as *"root"* and *"fdisk /dev/sdb"* [or whichever is/was your disk where you r installing ocfs2]
Once done, repeat the steps for configuring OCFS2. I was successfully able to mount the disk on both machines.
All this problem was apparently caused by not choosing "allocate all disk space now" option while creating the disk to be used for OCFS2.
If you still have any questions or problem, email me at [email protected] and I'll try to get back to you at my earliest.
Good luck!

Considering shared storage for Oracle RAC 10g

Hi, guys!
My Oracle RAC will be run on VMware ESXI 5.5. So, both 2 nodes and shared storage are on VM. Don't blame for this, I dont have another choice.
I am choosing shared storage for Oracle RAC. I am choosing between NFS and ISCSI server, both can be done in RedHat linux or FreeNAS.
Can u, guys, help me to do the choise?
RedHat or FreeNAS
ISCSI or NFS
Any help will be appreciated.

JohnWatson написал(а):
NFS is really easy. Create your zero-filled files, set the ownership and access modes, and point your asm_diskstring at them. Much simpler than configuring an iSCSI target and initiators, and then messing about with ASMlib or udev.
I recorded a public lecture that (if I remember correctly) describes it here, Oracle ASM Free Tutorial
I will be using OCFS2 as cluster FS. Does it make any difference for NFS vs ISCSI?

RAC with ASM and shared disks?

Hi all,
Can someone clarify this little point please. If I use ASM as my storage with a RAC database, I have to configure these nodes to shared disks. At least this is what the UG says ...
When you create a disk group for a cluster or add new disks to an existing clustered disk group, you only need to prepare the underlying physical storage on shared disks. The shared disk requirement is the only substantial difference between using ASM in a RAC database compared to using it in a single-instance Oracle database. ASM automatically re-balances the storage load after you add or delete a disk or disk group.
With my 9i databases, I used HCAMP to allow for concurrent VG access among the nodes. My questions are ...
1) How can I share this storage as stated above without using HACMP? My understanding is with 10g I no longer have to use it.
2) Can Oracle's clusterware be used to share storage? I have not seen any indication that it does.
3) Does this mean I still have to use HCAMP with 10g crs to allow shared storage?
Thank you

"...meaning visible to all the participating nodes, which you don't need HACMP..."
This is one step forward, but still not clear. On unix, storage is presented to ASM as raw volumes. As such, how can these volumes be visible on all nodes without using HCAMP (or whatever 3rd party clusterware you are using). Presenting raw volumes on several nodes is something that is not done at OS level without using some clusterware functionality.
I do understand that storage or LUNs can be shared at the SAN fabric level. But then, these LUNs are carved in bug chunks and I would like to be able to allocate storage at much granular level using raw partitions.
So all in all, here are my questions ...
1) On unix platforms, can ASM disks be LUNs, raw volumes, or may be both?
2) If raw volumes, how are these shared (or made visible) without using 3rd party clusterware? Having managed 9i RAC, it was the function of HACMP to make these volumes visible on all nodes, otherwise, we had to imp/exp VGs on all nodes to make them visible.
Thank you

Pointing existing RAC nodes to a fresh Shared Storage discarding old one

Hi,
I have a RAC Setup with the Primary Database on Oracle 10gR2.
For this setup, there is a Physical Standby Database Setup (using DataGuard configuration) also with 30min delay.
Assume that the "Shared Storage" of the Primary DB fails completely.
In the above scenario, my plan is to refresh a "fresh" shared storage device using Physical Standby Database Setup and then "point" the RAC nodes to the new "Shared Storage".
Is this possible?
Simply put, how can I refresh the Primary database using the Standby Database?
Please help with the utilities (RMAN, DatGuard, other non-Oracle products etc.) that can be used to do this.
Regards

Does following Shared Device configuration is fine for 10g RAC on Windows 2003?
. 1 SCSI drive
• Two PCI network adapters on each node in the cluster.
• Storage cables to attach the shared storage device to all computers.

Error installing clusterware 10gR2 with OCFS2 Storage

When i ran OUI to install clusterware, i get this error when i specified storage location to OCR as '/dev/sda4' -> The location /dev/sda4, entered for the Oracle Cluster Registry (OCR) is not shared across all the nodes in the cluster. Specify a shared raw partition or cluster file system file that is visible by the same name on all nodes of the cluster."
i have been checked the OCFS2 configuration based on technical doc from project site
Thanks in advance
