Hi Thomas, so you are seeing high load on your storage and you are asking
'why'? an answer with the facts you give would be: you are using your
storage, so, you have storage IO.
so, if you want to dive deeper:
-which storage are you using, specs would be nice.
-which host model are you using?
-network specs? card model, etc. switch model, etc.
hows your setup made? iscsi? nfs? gluster?
based on the former, we might get a better idea and after this some tests
could be made if needed to find if there's a bottleneck or if the
environment is working as expected..
regards,
