The /proc/fs/lustre/health_check file on the client does not currently report anything besides health=healthy, since this is only wired up to report request handling state on the server nodes, and if the ldiskfs filesystem has been mounted read-only.

It would be desirable to have health_check print out the OSC and MDC import states on the client (e.g. if imp->imp_state != LUSTRE_IMP_FULL as long as the import is not marked imp_deactive).
