Abstract
Techniques for generating a crash-consistent clone of file(s) stored by a distributed file system are described herein. To generate the crash-consistent clone, a coordinator node may identify multiple nodes (e.g., at least a first node and a second node) of the distributed file system that are storing different portions of data of the file. The coordinator node may then send a first command to the multiple nodes to cause each of the multiple nodes to quiesce the file and clone the different portions of the data to generate the crash-consistent clone of the file. The coordinator node may then receive, from the multiple nodes, a status associated with generating the crash-consistent clone of the file. Based at least in part on the status, the coordinator node may send a second command to the multiple nodes to cause each of the multiple nodes to unquiesce the file.
