Dear support,
we are running Lustre 2.2 on our system and we noticed that also with a low usage of the file system, the MDS is always with a load avarage around 10 and comparing with Lustre 1.8.4 with a high I/O the MDS is basically always around load avarage of 1.80. Is this the normal behavior of Lustre 2.2?
