vm not starting - xenopsd internal error: Storage_interface. Illegal_transition()

[Paul Matthews]

Hi,

 

I've hit a problem resuming a suspended vm with the above error occurring.

A forced shutdown and subsequent restart sees the same response

 

The suspended state was to allow for an export which failed due to a typo and consequently filled up root space. This has since been cleared.  Whether this is related I am not sure but my guess it is.

 

The other thing I am seeing is mpathalert errors although multipath -l shows all paths active and there are no specific errors on the SR itself

 

I am reluctant to reboot the host as there are other production vms running so downtime is not easily available

 

Regards

Paul

I think I have found my problem and it is described here

http://support.citrix.com/article/CTX137243

 

As described:

This error occurs because the Control Domain (Dom0) on the XenServer which runs the VM, attaches the Virtual Disk Image (VDI) of the VM to Control Domain. This attached disk is then operated by the Control Domain to perform the operations which has been initiated on the VM. As the operation fails, the VDI is still attached to the control domain through a Virtual Block Device (VBD) connection that needs to be destroyed.

 

With suggested action being

1. #xe vbd-list vm-uuid=<uuid of the Control Domain>

2. Run the following commands to unplug and destroy the VBD:
   #xe vbd-unplug uuid=<uuid of the vbd>
   #xe vbd-destroy uuid=<uuid of the vbd>

 

I've not given this a go yet as I'm trying to understand it enough to convince myself this is a safe action but it sounds like this is the possible solution

If that doesn't work I would do a host restart.

I can confirm this resolved the problem

[Viral Patel1709159098]

I tried the above fix but when I run the command, I don't get any output. 

 xe vbd-list vm-uuid=<UUID of my Control DOmain>

 

The VM is still down and any attempt to start it will result in the error below:

Internal error: xenopsd internal error: Storage_interface.Illegal Transition

 

Any help is appreciated.

I have had the same issue (XenServer 7.3). Reboot has solved problem.

When I execute the command #xe vbd-list vm-uuid=<uuid of the Control Domain> I get this result:

I would like to know what is the UUID of the vbd in this case, thanks very much.
