Based on my reading: shutting down the file system including un-mounting clients, MDT/MGS,
and OST and then performing a writeconf would clear this permanently removed OST.
Question: I believe and also do not see any issue in continuing to run the file system
without having to shut down until the next scheduled maintenance, to run writeconf and
hence to clear deleted OST's from being listed on MDS. Do I get this right?
