Abstract: Techniques are provided for providing a fully active and non-replicated block storage solution in a clustered filesystem that implements cache coherency. In a clustered filesystem where one or more data blocks are stored in a respective cache of each host node of a plurality of host nodes, a request is received at a host node of the plurality of host nodes from a client device to write the one or more data blocks to a shared storage device. In response to the request, the one or more data blocks are stored in the cache of the host node and a particular notification is sent to another host node of the plurality of host nodes that the one or more data blocks have been written to the shared storage device. In response to receiving the notification, the other host node invalidates a cached copy of the one or more data blocks in the respective cache of the other host node.
