Abstract: A method for dynamic fault tolerance in a stretched storage cluster is provided. Embodiments include determining that data of a storage object is unavailable on a first site in a multi-site storage cluster comprising: the first site; a second site; and a witness node. Embodiments include modifying a voting arrangement for the storage object so that votes from the second site can achieve a quorum without any votes from the first site or the witness node. Embodiments include determining that the witness node is unavailable. Embodiments include, after determining that the witness node is unavailable, allowing data to be read from or written to one or more entities of the second site based on the quorum being achieved.
