Highly available network filer super cluster

One or more non-transitory computer-readable media storing a set of instructions, which, when executed by one or more hardware processors, cause:

• receiving, at a first cluster of nodes, a file system request for a first file;
• wherein each node in the first cluster of nodes has direct access to a first shared storage, on which a set of files is stored, and wherein the set of files includes the first file;
• wherein the first shared storage performs processing of requests for the set of files from a first plurality of nodes in the first cluster of nodes;
• wherein the first cluster of nodes is configured to replicate changes to the set of files, stored on the first shared storage, to a replica set of files stored on a second shared storage that each node in a second cluster of nodes, that is different from nodes in the first cluster of nodes, has access to;
• wherein the second shared storage performs processing of requests for the replica set of files from a second plurality of nodes in the second cluster of nodes;
• determining that the second cluster of nodes is to process the file system request;
• receiving, at a node in the second cluster of nodes, the file system request;
• and
• in response to receiving the file system request, processing, at the node in the second cluster of nodes, the file system request for a second file, in the replica set of files, that is a copy of the first file and is stored on the second shared storage.
