What you think about returning empty slice (i.e. default) in case of an error during parsing? I think this is more appropriate than having half parsed slice.

Let's use []uint32{handler.DefaultCopiesNumber} or drop handler.DefaultCopiesNumber.
Probably we can skip initialization of this field because empty/nil vector leads to default behavior (the same as vectore with one element 0)

Since this PR is about refactoring. Can we move this check to line 162? It's minor, but still

Should we use here this

l.Info("added constraint", zap.String("location", constraint), zap.Uint32s("copies numbers", vector32))

?

Info will be more consistent with other similar cases. And it will be more convenient to see this information about copies number without any changes on cluster (where logging level is info)

@ironbee @alexvanin I forgot, should this PR reload frostfs.set_copies_number and placement_policy.copies_numbers by SIGHUP?
