PROVIDING TRANSPARENT FAILOVER IN A FILE SYSTEM |
摘要 |
<p>A connection state system is described herein that allows a client to resume a connection with a server or a different replacement server by remotely storing client state information in association with a resume key. The system provides a resume key filter operating at the server that facilitates the storing of volatile server state information. The state information can include information such as oplocks, leases granted to a client, and in-flight operations on a file handle. The resume key filter driver sits above the file system, which allows multiple file access protocols to use the filter. Upon a failover event, such as a server going down or losing connectivity to a client, the system can bring up another server or the same server and reestablish state for file handles held by various clients using the resume key filter.</p> |
