When using VMware virtual machines, many users experience the error "The Operation Was Cancelled by the User". This error is caused when too many storage operations are taking place concurrently in the same disk. It's important to understand when and how this error occurs, and how to fix it.
Symptoms of the Error
The "The Operation Was Cancelled by the User" error generally originates from VMware's vstor2 devices. The following symptoms may occur when encountering this error:
- VMware Tools installation fails
- Virtual machine fails to start
- Activation fails
- Deleting or renaming files fails
- Files are closed unexpectedly
- Unexpected dialog boxes or screens appear
Causes of the Error
The "The Operation Was Cancelled by the User" error is triggered by too many storage operations being conducted on the same disk concurrently. This can occur when a program tries to install a file at the same time another program is deleting or writing to the same disk. It can also be caused when a virtual machine operation tries to use the same disk at the same time as another operation. Additionally, if the disk is running in a RAID configuration, this can cause the error since RAID causes conflicts in storage operations.
Solution
Fortunately, this error can be easily resolved by disabling RAID in the virtual machine's Configuration menu. Disabling RAID and restarting the virtual machine should solve the problem. If disabling RAID does not work, try changing the Disk Mode option to "Independent-Persistent" and restarting the virtual machine.
FAQ
What is the "The Operation Was Cancelled by the User" error?
The "The Operation Was Cancelled by the User" error is an error caused by too many storage operations taking place concurrently on the same disk in VMware virtual machines.
What are the symptoms of the error?
The symptoms of the error include: VMware Tools installation fails; virtual machine fails to start; activation fails; deleting or renaming files fails; files are closed unexpectedly; and unexpected dialog boxes or screens appear.
What are the causes of the error?
The "The Operation Was Cancelled by the User" error is caused by too many storage operations being conducted on the same disk simultaneously. This can occur when a program tries to install a file at the same time another program is deleting or writing to the same disk, and when a virtual machine operation tries to use the same disk at the same time as another operation. Additionally, if the disk is operating in a RAID configuration, this can cause the error since RAID causes conflicts in storage operations.
How can the error be fixed?
The error can be fixed by disabling RAID in the virtual machine's Configuration menu and restarting the virtual machine. If disabling RAID does not work, try changing the Disk Mode option to "Independent-Persistent" and restarting the virtual machine.
What are the alternatives to fixing the error?
The alternatives to fixing the error are to try restarting the virtual machine, removing hardware from the virtual machine, disabling unused hardware in the virtual machine, and increasing the amount of RAM or CPU allotted to the virtual machine.
