NAME


clear_locks - clear locks held on behalf of an NFS client

SYNOPSIS

DESCRIPTION


The clear_locks command removes all file, record, and share locks created
by the hostname and held on the current host, regardless of which process
created or owns the locks.

crashing and failing to clear held locks. Clearing locks held by an
active client may cause applications to fail in an unexpected manner.
