Claim Text:
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; enabling the legacy file system filter driver at the cluster device after the CSV filter driver is enabled; 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, wherein the replication filter is different than the legacy file system filter driver.
