auto-read-only is an internal state of the RAID array, it has nothing to
do with file systems. So you probably won't find anything in the
locations you mention above; auto-read-only is only displayed in
/proc/mdstat. Look at the mdadm man page and read the sections "Auto
Assembly" and "INCREMENTAL MODE".
