The disclosed computer-implemented method for making snapshots available may include (i) identifying a writeback log that records input/output operations of a compute node within a high-availability environment, (ii) placing, in the writeback log, a marker that indicates a start of a snapshot to be stored on a data node, (iii) marking, after placing the marker and before all data within the snapshot has been transferred to the data node, the snapshot as available, (iv) receiving, from an additional compute node, a request to read from the snapshot, and (v) sending, from the compute node to the additional compute node, metadata indicating which portion of data from the snapshot is stored on the data node and which portion of the data from the snapshot is not stored on the data node but is stored in the writeback log. Various other methods, systems, and computer-readable media are also disclosed.
