VMWare ESX Server error: An invalid snapshot configuration was detected


While trying to create a snapshot on a host I received an error: 
An invalid snapshot configuration error occurred. 

Tech support was good and walked me through the resolution:

#
vmware-cmd -l

[gets a listing of hosts and filesystem paths and combine the host that you are getting the error on with the
vmware-cmd command:

#
vmware-cmd /vmfs/volumes/45j2fdb8-42a8bc40-dd01-0019bbca5388/host.com/host.com.vmx hassnapshot

[if there are no snapshots you will see this output]

hassnapshot() = 1

#
ls -la *vmsd
-rw------- 1 root root 477 Sep 19 19:49 host.com.vmsd

#
mv host.com.vmsd host.com.vmsd.bak

then issue the snapshot command.

You saved my day!

Now the TDS backup is working again on this server.

TDS backup stands for Tomato Disaster solution. It is very good and with DataDomain it perfect to backup virtual servers..
