All Open/Lock state held by the client will be released. After revocation, the client will no longer be able to use state on the server until it does a fresh SetClientID/SetClientIDConfirm operations sequence. THIS SHOULD BE DONE AS A LAST RESORT ONLY, when clients are holding state that must be released on the server. .Pp The .Ar ClientId argument is a hexadecimal string, which is the last field of the .Xr nfsdumpstate 8 command's .Fl o and .Fl l options output. .Sh SEE ALSO .Xr nfsv4 4 , .Xr nfsdumpstate 8 .Sh HISTORY The .Nm command was introduced as a part of the experimental nfs server subsystem.
