Check if the virtual machine still has a World ID assigned to it:. On the ESX host where the virtual machine is still running, kill the virtual machine. This releases the lock on the file. To kill the virtual machine, run this command:. Note: This command takes minutes to complete. Determining if the file is being used by a running virtual machine If the file is being accessed by a running virtual machine, the lock cannot be usurped or removed.
It is possible that the host holding the lock is running the virtual machine and has become unresponsive, or another running virtual machine has the disk incorrectly added to its configuration prior to power-on attempts. To determine if the virtual machine processes are running: 1. Determine if the virtual machine is registered on the host run this command as the root user:. Assess the virtual machine's current state on the host, run this command:. To address this issue, see To stop the virtual machine process, see Powering off an unresponsive virtual machine on an ESX host If the ESX specific steps above identified the owner of the lock, proceed to these troubleshooting steps.
ESXi troubleshooting steps Identifying the locked file To identify the locked file, attempt to power on the virtual machine. The output returns a list of the virtual machines registered to the ESXi host. Each line contains the datastore and location within of a virtual machine's. Verify that the affected virtual machine appears in this list. If it is not listed, the virtual machine is not registered on this ESXi host. The host on which the virtual machine is registered typically holds the lock.
Ensure that you are connected to the proper host before proceeding. This host is identified by the MAC address of the primary management vmkernel interface. This reduces the amount of lock troubleshooting to just the VMkernel. For servers prior to ESXi 4. From ESXi 4. In versions of ESXi equal or greater than 4. Note: If you have already identified a VMkernel lock on the file, skip the rest of the steps in this section.
On the ESXi host where the virtual machine is still running, kill the virtual machine. For ESXi 5. Obtain a list of all running virtual machines, identified by their World ID, Cartel ID, display name, and path to the. Two worlds are listed. The second world number in this example, is the virtual machine Cartel ID.
For additional information, see Mapping a virtual machine world number to a virtual machine name In ESXi 4. To generate a core dump after killing the running virtual machine but hung and nonresponsive , use the command kill -6 PID or kill PID. Note: In ESXi 4. Run the esxtop utility using the esxtop command. Press c to switch to the CPU resource utilization screen.
Press c to add the column for the Leader World ID. Press k. Wait 30 seconds and validate that the process is no longer listed. Determine if the virtual machine is registered on the host, run this command as the root user:. The output lists the vmid for each virtual machine registered. Record this information as it is required in the remainder of this process on the ESXi server. Further troubleshooting steps These steps are applicable to both ESX and ESXi Using the touch utility to determine if the file can be locked The touch utility is designed to update the access and modification time stamp of the specified file or directory.
As such, the command can be used to test the file and directory locking mechanism in the VMFS filesystem, where the procedure is expected to fail on locked files. Using touch is the preferred method because the changes to the resource are minimal. At this point, retry the virtual machine power-on operation to see if it succeeds.

For this, the initial step is to identify the locked files. Also, note the Mode value:. Today, we saw how our Support Engineers fix this error. Never again lose customers to poor server speed!
