VMware: Virtual Machine Failed to Power-on due to Disk Consolidation-Snapshot-Issue

• VM failed to power after storage outage or snapshot removal. 
• vCenter shows Virtual Machine disk consolidation is needed alert.
• Performing a Disk Consolidation fails and shows that Another task is in progress.

This issue occurs when the filename-ctk.vmdk file is missing.

Example of error log:

1. Check the task list for the VM Collecting information about tasks in VMware ESXi. See Broadcom article 1013003 Collecting information about tasks in VMware ESXi 

# vim-cmd vimsvc/task_list VMID 

2. Kill the process

# lsof | grep vm-name
# kill -9 process-id 

3. Move all the CTK files into a temp folder

# mkdir temp
# mv *-ctk.vmdk 

4. Comment the change, tracking file line in all .vmdk, present in .vmx

# less .vmx | grep .vmdk 
# vi .vmdk
# :wq! 

5. Create a copy of the vmx file, and then edit it to change from TRUE to FALSE

# cp vm-name.vmx vm-name.vmx.bck
# vi vm-name.vmx
scsix:x.ctkEnabled = "TRUE" ----> scsix:x.ctkEnabled = "False" 

6. Save the file, and reload the vmx file

# vim-cmd vmsvc/reload VMID 

See VMware article 2009244 ERROR: "could not open/create change tracking files" when powering on the VM 

7. You should now be able to successfully power on the VM. The consolidation is in progress.
