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.
Claims20
A method comprising:
- initiating, by a processing device, a snapshot of a volume distributed across a plurality of storage nodes of a distributed file system;
- creating in the plurality of storage nodes, by a snapshot management system executed by the processing device, a first writeable sub-volume associated with the volume of the distributed file system;
- identifying, by the snapshot management system, a second writeable sub-volume associated with a previous snapshot taken prior to initiating the snapshot;
- and
- marking, by the processing device, the second writeable sub-volume of the distributed file system as read-only.

A system comprising:
- a memory;
- and
- a processing device operatively coupled to the memory, the processing device to:
- create, by the processing device, a first writeable sub-volume associated with a volume distributed across a plurality of storage nodes of a distributed file system;
- identify, by the processing device, a second writeable sub-volume associated with a previous snapshot;
- and
- marking, by the processing device, the second writeable sub-volume of the distributed file system as read-only.

A non-transitory machine-readable storage medium storing instructions that cause a processing device to:
- initiate, by a processing device, a snapshot of a volume distributed across a plurality of storage nodes of a distributed file system;
- create, by the processing device, a writeable sub-volume associated with the volume of the distributed file system;
- and
- mark, by the processing device, the volume of the distributed file system as read-only.
