      There have been several occurrences in Atlas where one or more secondary nodes already have an index built that the primary does not have. We think this is due to interrupted rolling index builds. Creating the same index on the primary may result in the index build stalling indefinitely as the secondary nodes with the index will return early and skip voting for the index's commit quorum.

      The workaround is to adjust the commit quorum using the setIndexCommitQuorum command.

      It would be ideal if secondary nodes with the index already existing could participate in voting for the commit quorum to avoid this.
