Flexible Storage Sharing provides great capabilities to reduce capital and operational expenditures. In a previous blog entry I was describing how to commoditize high availability and storage using Flexible Storage Sharing. Later we saw in this article how to add an extra node to the cluster. In this blog entry I am going to describe my next step that was to have a database instance running in each cluster node. My idea here was to provide resiliency by having a mirror of my data and redo logs in at least two servers. With this approach, each node will have a local copy of the database that is running plus a mirror for another instance. This will be the architecture I will be using:

In the article Commoditizing High Availability and Storage using Flexible Storage Sharing I described my first attempt to create a two node cluster based on Flexible Storage Sharing within Symantec Cluster File System and the nice results that I got. My next step was to increase the node count as I wanted to move to an architecture where a database will be running in each of the nodes. The first step here was to add a new node to the cluster.

Many times I get the question about how easy or difficult is to add a node to the cluster. This was a good opportunity to document what I did here. Our engineers at the Common Product Installer (CPI) group have done a great job over the years and now adding a node to the cluster can be done with a few easy steps.

The first thing to do is deploy the packages on the new server. There are several ways to do...

Intel has 3 models depending on your workload plans starting at $500. Symantec Smart I/O delivers the fastest storage performance with no single point of failure. Fusion-io is delivering PCIe cards with up to 2.6GB/s throughput. Smart I/O can be used to deliver highly available applications. Here are the top benefits:

  1. Increased Application Performance – bring data closer to the application and avoid the SAN bottleneck
  2. Reduce Storage Costs – decouple IOPs and capacity, you can now use tier 2 and 3 storage for your most demanding applications
  3. Improved Storage Utilization – shared storage deployments with Cluster File System, you can even implement DAS and use Symantec Flexible Storage Sharing feature

It was during this year VISION conference in Las Vegas when I got a very interesting question from Mike. He was running my Flexible Storage Sharing (FSS) lab and he asked me: “So Carlos, with FSS I can use internal HDDs and provide a highly available service, commoditizing the HW and avoiding any SAN need”. Then I started talking about the work I have being doing in the lab for the last months. And it was when I realized I had to start writing and publishing about that work, so here we go.

During FSS deployment we all were very excited about the capabilities to bring any application working close to the CPU, especially when using internal SSDs. We worked very closely with Intel and we published the white paper Remove the Rust: Unlock DAS and go SAN-Free. This white paper described how I could increase by four times the performance of a database. But what happens if I do not...

Here is a troubleshooting scenario that we thought would be useful to share.

If you try to deport dg , and meet the following error:

VXVM vxdg ERROR V-5-1-584 Disk Group XXX: Some volumes in the  disk group are in use.

First, confirm that the application has stopped.
But ps -ef  can see  many application process.
Manually kill all  application processes, deport  dg , error still.
df  -k  can  see io error entry:
df:/mountpoint :There is an input or output error.

then  umount  /mountpoint

deport  dg  again,  problem  solved.
