Why was it done that way? I do not understand the reason why distributing
the IOPS accross different disks, when the measurement
we have is for one
disk alone. This means with default parameters we will always be far from
reaching OSD limit right?
It's not on different disks. We distribute the IOPS across shards on a
given
OSD/disk. This is an internal implementation detail.
This means in your case, 450 IOPS is distributed across 5 shards on the
same OSD/disk. You can think of it as 5 threads
being allocated a share of the total IOPS on a given OSD.
