We have a Cephfs cluster stuck in read-only mode, looks like following the
Disaster Recovery steps, is it a good idea to first make a RADOS snapshot of

Don't do this. Pool-level snapshots are incompatible with so-called
"self-managed" snapshots where something above rados (cephfs/rbd) is
handling snapshots.
