When Taking Snapshot while VM is powered on Receiving error: DISKLIB-CHAINESX : ChainESXOpenSubChainNode: can't create deltadisk node XXXX.vmdk failed with error The system cannot find the file specified (0xbad0003, Not found)

[sm0kescreen]

I am getting the following error when trying to create a snapshot (while the VM is powered on) using VSphere Center or API.  If the VM is not powered on I do not get the error.  I search the KB and the web and see similar type errors but not the exact error I am receiving.

DISKLIB-CHAINESX : ChainESXOpenSubChainNode: can't create deltadisk node 1b7e0869-TEST-000001-delta.vmdk failed with error The system cannot find the file specified (0xbad0003, Not found)

Details:

Version:  ESXI 4.1.0 Build 348481 free version.

Steps that I did to create the error.

1. Created new Test virtual server with no OS for testing purposes.

2. In VSphere I right clicked the VM and choose snapshot, take snapshot (I unchecked both the memory and quiesce options)

3. After a few seconds the VM goes down and never powers up.  I checked the vmware.log in the VM's folder and I found the error mentioned above.

I have attached the contents of vmware.log to this post.

Thanks for your help!

Which type of storage you used?

If you use NFS, then take a look at Virtual machine freezes temporarily during snapshot removal on an NFS datastore in a ESX/ESXi 4.1 ho...

I'm not sure, but possible it is your case

VTsukanov,

Thanks for the reply.  Yes I am using NFS for a datastore.  I applied the patch recommended in the link you sent but I am still getting the same error.

Try to use other storage (local vmfs for example) and other VM name (Test01 for example) and repeat your steps reproduce the error
