A method and system for integrating anti-virus in a clustered storage system. A clustered storage system provides anti-virus scanning with third-party software components. Specifically, the clustered storage system receives a request for data from a client, identifies the data requires scanning and scans the data for viruses with third party software components that have been previously provided by any one of a number of third party software vendors.

Integrating anti-virus in a clustered storage system

A system receives a scan request for a storage object in a clustered storage system. The system determines if an anti-virus (AV) server is executed on a preferred node in the storage system. The system requests information describing a plurality of nodes on the clustered storage system from a service manager. This information is used to select an alternate AV server which is executed on a substitute node if the initial AV server is not executed on the preferred node. The scan request is sent to the initial AV server if the initial AV server is executed on the preferred node. The scan request is sent to an alternate AV server if the initial AV server is not executed on the preferred node.

Load balancing of scan requests to all antivirus servers in a cluster

A volume metadata manager manages volume metadata including antivirus attributes. When a volume is to be relocated, the volume metadata manager updates a generation indicator in volume-level metadata for the volume but does not update a generation indicator in file-level metadata for a file in the volume. After the volume is relocated, the volume metadata manager updates the generation indicator and antivirus attributes of the file when the file is requested for access.

A method and system for integrating anti-virus in a clustered storage system. A clustered storage system provides anti-virus scanning with third-party software components. Specifically, the clustered storage system receives a request to access data from a client, retrieves the data from storage, and scans the data for viruses with third party software components that have been previously provided any one of a number of third party software vendors. If the data is free of viruses, the clustered storage system communicates the data to the client. Otherwise, the clustered storage system attempts to apply remedial actions to the infected file. For example, the clustered storage system may attempt to repair the file by removing the virus. If remedial action successfully removes the virus, the clustered storage system communicates the requested data to the client. Otherwise, the clustered storage system communicates an access denied message to the client.
