Abstract
Methods and systems are disclosed to initiate a snapshot of a volume distributed across a plurality of storage nodes of a distributed file system. The systems may create in the plurality of storage nodes a writeable sub-volume associated with the volume of the distributed file system. The system may identify a previous writeable sub-volume associated with a previous snapshot and mark the previous writeable sub-volume as read-only.
