Detailed Description

The Revoke-NfsClientLock cmdlet releases locks that a client computer currently holds for files that a Network File System (NFS) server shares. You can select the locks to revoke by specifying the path of the files. The Path parameter supports wildcards, so you can revoke multiple locks that match the specified pattern.

You can revoke NFS v4 protocol locks by specifying the state identifier of the locked files. You can revoke NFS v3 protocol locks by specifying the computer name of the NFS client that holds the lock on the files.

Parameters

-AsJob

Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete. The cmdlet immediately returns an object that represents the job and then displays the command prompt. You can continue to work in the session while the job completes. To manage the job, use the *-Job cmdlets. To get the job results, use the Receive-Job cmdlet. For more information about Windows PowerShell® background jobs, see about_Jobs.

-ThrottleLimit<Int32>

Specifies the maximum number of concurrent operations that can be established to run the cmdlet.

The throttle limit applies only to the current cmdlet, not to the session or to the computer.
