RDM Disk corruption on Microsoft Failover Cluster


Recently I’ve been working on a fresh new vSphere 6 environment and we wanted to test a new functionality, vMotion of clustered guest VMs with RDM.

We created and configured Windows Server Failover Cluster solution (WSFC) in accordanced with VMware's Best Practices and then vMotion it to another hosts, as expected successfully !!!

Then we decided to change the Multi Path Policy of the RDM disk to Round Robin, already supported since vSphere 5.5, when we vMotion the clustered guest VM ,in this specific scenario, we faced a disk corruption on the WSFC solution.

Checking the guest OS you would see a few events:

Source: NTFS
Event ID: 57
Message: The system failed to flush data to the transaction log. Corruption may occur.


 At this point the RDM (Raw Device Mapping) disk was not online anymore.

Source: FailoverClustering
Event ID: 1066
Message: Cluster disk resource indicates corruption for volume


 Trying to bring the disk online again is useless. The disk is fully corrupted by now.

Source: NTFS
Event ID: 55
Message: The file system structure on the disk is corrupted and unusable. Please run chkdsk utility on the volume.


We get not luck to repair the disk even running check-disk and we had to restore the data back from a backup.

Well, after some extensive troubleshooting, it has been confirmed by VMware, it was a bug when the use of these two things in combination.

-       vMotion of the guest VM with RDM.
-       RDM disk configured with Round Robin as Path Selection Policy.

Luckily VMware, has already released the hotfix that fixes this bug on March, 04th.

If you are in an environment like that, it's extremely recommended that you install this hotfix as soon as possible.


If for some reason you cannot install the hotfix, there’s a workaround that will prevent the disk corruption. Just change your Policy Multi Path to FIXED.
That’s it, the bug just occurs when the PMP is set to Round Robin.

See you…

Scheduling vRO workflows


Do you know that amazing vRealize Orchestrator workflow of yours, would not you like to run it automatically or from time to time?!?!
Well, vRO has a scheduler engine, so you can schedule your workflows to run at the specific time, let’s see how it works !!!

-       Right click the workflow you want to schedule and select Schedule workflow


-       Give it a name, recurrence type, recurrence end date (leave it blank if you want to run it indefinitely) and click Submit

There’s a few recurrence type as Every hour, day, month…. But curiously, even thoug I pick Every day it will not run once a day only as you might think off, as you can see on the screen, I can add multiple entries that will kick-off my workflow, on the example it will run daily at 14:30 and 18:30.

How do I change the schedule once I created it ?
It’s even simpler.

-       Click the Scheduler tab and select the schedule you just created.
-       On the right you will see it’s details, click on the pencil to edit it.
