Is the order important when installing ocfs2 and Oracle RAC?
Is the order important when installing ocfs2 and Oracle RAC?
If you have an existing RAC installation and you want to use ocfs2 for shared files but not for the OCR or Voting Disks, do you need to reinstall the Oracle Clusterware after installing OCFS2?

Nick Donatone

Corrupt inodes on shared disk...
I am having problems when using a Dell PowerVault MD3000 with multipath
from a Dell PowerEdge 1950. I have 2 cables connected and mount the
partition on the DAS Array. I am using RHEL 4.4 with RHCS and a two
node cluster. Only one node is "Active" at a time, it creates a mount
to the partition, and if there is an issue RHCS will fence the device
and then the other node will mount the

mixed environment / why is setting up an oracle cluster on windows so hard?
hello everybody
I successfully installed a *very* small two node cluster with a shared
volume on linux (both debian, one x86, one ARM [laugh not: NSLU2 :)]).
before that, I tried to install the "clusterware" package on my windows
xp box and it constantly complained about the three different ip
addresses it wanted to see, then I got so frustrated with numerous

Question about increasing node slots
We have a test 10gR2 RAC cluster using ocfs2 filesystems for the
Clusterware files and the Database files.
We need to increase the node slots to accomodate new RAC nodes. Is it
true that we will need to umount these filesystems for the upgrade (i.e.
Database and Clusterware also)?
We are planning to use the following command format to perform the node
slot increase:
# tunefs.ocfs2 ?N 3

Recommendations
We have two virtual machines on ESX 3 running CentOS 4.3 and we'd like
to turn them into some sort of highly available nfs file server.
Currently, I am familiar with DRBD and RHCS but I was curious what
others might recommend in such a situation.
I'm not sure how easily we could use RHCS in such a situation because we
don't really have the advantage of shared storage in this setup.

telnet to serial connection?
hello folks!
here's my situation: i've got two WTI RPB+ remote power switches
(essentially a 5-port power strip which you can control via serial
interface to make each of the ports switch on and off
independently). they work fine; i plug a DB-9 cable into the back of
my machine, fire up minicom, and i have full control.
however, my eventual plan is to use these as fencing

RHCS on CentOS4 - 2 node cluster problem
Hello fellows,
I have a problem with a 2 node RHCS cluster (CentOS 4) where node 1
failed and node 2 became active. That happened already last year and due
to holidays the customer didn't recognize it. The cluster is just a
failover for Apache and has no shared storage space.
Customer now saw the situation, tried to fix it by rebooting node 1,
which then failed to come back up. As

Apache/Cluster issue -- Single public IP address
I want to set up a cluster that is used for web hosting (RHCS cluster). Recently,
I experimented with a 2 node cluster and was able to run it successfully. However,
I have started facing some issues with Apache, which I had configured as a service
using the Cluster configuration tool. To do this Apache needs a floating IP address.
This address is in addition to the network interface IP address.

ocfs2 <-> 10G (10.2.01) Clusterware
RHEL 4 (CENT OS)
Am I waisting my time trying to get the 10G Clusterware installer to use OCFS2 volumes for the voting and OCR disks ?
The ocfs2 setup seems happy on both nodes but the 10G installer says
the location entered for the oracle cluster registry (OCR) is not shared across all the nodes in the cluster
Do the volumes need to mounted ? I did with no change .

Failed to start a "virtual machine " service on RHCS in CentOS 6
Hi? All:
I have two physical machines as KVM hosts (clusterA.RHCS and clusterB.RHCS) , an iscsi target set into GFS.
All I want is a HA Cluster which could migrate all the virtual machines on a node to another when the first node failed into some error status.
So I created a cluster "cluster" using RHCS ,added the two hosts into the cluster . created a fence device .

Hi,
I would like to ask about status of VDE and libvirt. I found a thread
from http://www.redhat.com/archives/libvir-list/2008-February/msg00030.html.
I am not interested in connecting the VDE to the outside world. I have

attach machines from different zones (dmz, prod, cust). I was thinking
on using VDE and vlans (FW would
