Pro-active self-healing in a distributed file system

摘要

A first storage server identifies a second storage server connecting to a cluster of storage servers in a file system. The first storage server locates a file in a replication directory hierarchy in the second storage server. The file has not been accessed by a client application. The first storage server determines, prior to the file being accessed by the client application, that the file on the second storage server has stale data and overwrites the stale data in the file on the second storage server with current data.

主权项

1. A method comprising:
requesting, by a processing device on a first server, a link status for a network port related to a second server; determining, by the processing device, that the second server after a failure is reconnecting to a cluster of servers in a file system in view of the link status for the network port; determining, in response to determining that the second server is reconnecting to the cluster of servers in the file system, that an image file on the second server comprises stale data; updating the stale data in the image file on the second server with current data; and responsive to detecting a request to access the image file, providing an indication during the updating that the image file is partially locked at a portion comprising the stale data.
