Abstract
Systems and methods for enforcing consistency of file to storage node mappings in distributed file systems. An example method may include: receiving a request to perform a file operation with respect to a file associated with a volume of a distributed file system; identifying, among a plurality of storage nodes of the distributed file system, a storage node associated with the file; obtaining a lock of a layout of the volume; and responsive to determining, by a processing device, that a directory layout version number matches a volume layout version number, performing the requested file operation with respect to the file.
