Bug 1942013

upstream docs had the wrong flag names   pr to fix: https://github.com/ceph/ceph/pull/40447

flags will be   --realm and --zone  once this is merged

using --rgw-realm and --rgw-zone dont do anything

both flags and positional arguments are supported

Daniel do we need to backport https://github.com/ceph/ceph/pull/40447 to pacific?

Ken it was already back ported in this pr from sage https://github.com/ceph/ceph/pull/40437

Ok, thanks. That PR is in the v16.2.0 upstream tag, so it will be in today's downstream rebase.

these flags --rgw-zone , --rgw-realm in addition to all the flags in this file https://github.com/ceph/ceph/blob/47d00f6503c721932547533a0ada89c221987736/src/common/legacy_config_opts.h

are accepted to every single ceph,ceph-mon,ceph-mgr,radosgw-admin,..... command 

it's the way the ceph CLI works basically any config option can be specified via the CLI for any ceph daemon/executable


examples:
[ceph: root@vm-00 /]# ceph -s --pid-file t            
  cluster:
    id:     827aca78-97e0-11eb-b38a-525400a09620

    mgr: vm-00.hehsce(active, since 22m), standbys: vm-02.bxtxvm
    osd: 3 osds: 3 up (since 19m), 3 in (since 19m)
 
  data:

[ceph: root@vm-00 /]# ceph orch host ls --mempool_debug

the problem here was the documentation was wrong thats been fixed and verified

if these flags being accepted here is a problem, there is a much bigger problem outside the scope of cephadm
