Summary:Techniques are disclosed relating to fencing out a first one of a plurality of nodes configured to handle requests for data stored in a distributed storage. A database system, in various embodiments, stores a value indicating that the first node is permitted to update a catalog stored at a metadata server. In response to a determination to prevent the first node from updating the catalog and writing to the distributed storage, in various embodiments, the database system updates the value to indicate that the first node is not permitted to update the catalog and instructs the distributed storage to prevent write operations to a particular portion allocated to the first node for writing data.
