Category Hyper-V

It’s a dark night, you’re in a cold murky alley.   There’s a random file found in the root of your drive (or mount point).   Suddenly, your cluster goes offline.   WTF!

If you’re thinking, “Damnit, what did my storage vendor do now!” You’d be mistaken.

There’s this little doozy out there:

“A physical disk resource may unexpectedly fail or go offline when the IsAlive function is executed on a Windows Server 2008 cluster node” to the tune of Q953652

Microsoft declares it to happen when you meet the following scenario:

• You have a Windows Server 2008 cluster node.
• The IsAlive function is executed on the cluster node while a file is being accessed in the root folder of the cluster disk.

In this scenario, a physical disk resource on the Windows Server 2008 cluster node may unexpectedly fail or go offline. This behavior occurs randomly.

Or otherwise read as: If you have a file in the root of Drive letter or Mount point, the drive may ‘disappear’ when you have this configured in a cluster (This does not apply to Server 2008 single servers)

Quite often this is blamed on the storage (regardless of vendor) so be sure to keep your clusters up to spec and make sure to apply this Hotfix from Microsoft, especially if you meet this criteria!

Good luck Clusters, and those cold dark alleys won’t be so bad.

Every so often I get asked by people for help improving their skills, making them more marketable as well as ways to get access to training and resources.

And more often than not, I lead them in directions with the huge cost of $0.00 associated with it.    Whether you’re looking for Certification, access to Labs, E-Books, or Training information.

I’m a BIG fan of Free!

So, can you afford freE-Learning?

If you saw my previous post about the voucher to get the Hyper-V training for free, this training is very complimentary to that and more! (Especially since that voucher seems to be faulty at the moment)

So get out there, get yourself something Free for this season.  It’s your education, do something about it!

For those of you who have not seen this newly released Out of Band Critical Security Update, you should check out MS08-078 What does this mean exactly? Here is Microsoft’s Take:

Executive Summary

This security update resolves a publicly disclosed vulnerability. The vulnerability could allow remote code execution if a user views a specially crafted Web page using Internet Explorer. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.

This security update is rated Critical for Internet Explorer 5.01, Internet Explorer 6, Internet Explorer 6 Service Pack 1, and Internet Explorer 7. For information about Internet Explorer 8 Beta 2, please see the section, Frequently Asked Questions (FAQ) Related to This Security Update. For more information, see the subsection, Affected and Non-Affected Software, in this section.

The security update addresses the vulnerability by modifying the way Internet Explorer validates data binding parameters and handles the error resulting in the exploitable condition. For more information about the vulnerability, see the Frequently Asked Questions (FAQ) subsection under the next section, Vulnerability Information.

This security update also addresses the vulnerability first described in Microsoft Security Advisory 961051.

Recommendation. Microsoft recommends that customers apply the update immediately.

What does this really mean?

Update any and all machines which have Internet Explorer installed on them, in order to prevent the Remote Code Execution attacks from being successful against your machines.

Just because you don’t use IE does not limit your vulnerability, so DO Upgrade!

This applies to all versions of windows (2000, XP, Vista, 2003, 2008) So get that update!

Thanks Kurt Shintaku for the heads up!

Code should be valid now!
