Hi lists,
Currently the ceph status output formats all numbers with binary unit
prefixes, i.e. 1MB equals 1048576 bytes and an object count of 1M equals
1048576 objects. I received a bug report from a user that printing object
counts with a base 2 multiplier is confusing (I agree) so I opened a bug and
https://github.com/ceph/ceph/pull/19117.
In the PR discussion a couple of questions arose that I'd like to get some
opinions on:
- Should we print binary unit prefixes (MiB, GiB, ...) since that would be
technically correct?
+1
- Should counters (like object counts) be formatted with a base 10
multiplier or a multiplier woth base 2?
+1
My proposal would be to both use binary unit prefixes and use base 10
multipliers for counters. I think this aligns with user expectations as well
as the relevant standard(s?).
Most users expect that non-size counters - like object counts - use base-10,
and size counters use base-2 units. Ceph's "standard" of using base-2
everywhere was confusing for me as well initially, but I got used to that...
Still, wouldn't mind if that would get sorted out once and for all.
