Dear All,
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?
Please advise.
Thank you,
Amit H. Kumar

Indeed, if you make sure the OST is deactivated on your MDT as well as on all clients, it
will not bother your filesystem.
We have an old cluster that is slowly shut down by emptying OSTs and switching off their
OSS - I believe we have many more deactivated OSTs now than
active ones. No trouble to be seen.
Regards,
Thomas
