CLUSTER SHARED VOLUME REPLICATION |
摘要 |
Systems and methods for replicating input-output (I/O) events of a cluster shared volume (CSV) are presented. Such systems may include a cluster device or node (in a cluster of devices), a coordinator node, and a replica server. Replication techniques disclosed herein may include capturing, using a processor operatively associated with a cluster device, a direct I/O event generated at the cluster device (e.g., by a virtual machine). A legacy file system filter driver of the cluster device may be used and enabled to perform the capturing of the direct I/O event. The legacy file system filter driver may be different than a CSV filter driver associated with the CSV, and may be enabled after the CSV filter driver is enabled. The captured direct I/O event may then be transmitted to the replica server using, e.g., a replication filter, to maintain a backup copy of the event at the replica server. |

1. A method to replicate input-output (I/O) events of a cluster shared volume (CSV), the method comprising:
capturing, using a processor operatively associated with a cluster device, a direct I/O event associated with the cluster shared volume, the direct I/O event generated at the cluster device and captured using a legacy file system filter driver of the cluster device, wherein the legacy file system filter driver is different than a CSV filter driver at the cluster device, the CSV filter driver associated with the cluster shared volume; and transmitting, using the processor, the direct I/O event from the cluster device to a replica server using a replication filter at the cluster device. |
