To respond to myself: after about 18 hours, self-heal seemed to finish. I then unmounted the gluster directory on all machines and restarted the gluster daemon and it all seems fine. This is the second time this has happened to us in about six weeks. The first time was after one of the servers was down for a few days, but Friday's incident seemed to be provoked by heavy usage of the file system and not by any disruption to the network or service. In the previous incident, there weren't any suggestions of problems either.
