Sorry, it's just the argument to the command:
osd test-reweight-by-utilization dry run of reweight OSDs by
{<int>} {<float>} {<int>} {--no- utilization [overload-percentage-for-
increasing} consideration, default 120]
so you want something like
ceph osd test-reweight-by-utilization 110
(as in 110%. Yes the arguments and units are super annoying and
confusing. This command is eventually going away though... the idea is
that the mgr will just do this on its own without the admin needing to get
involved.)
