This bug comes to us from Patrick Preisler. He discovered that it was not possible to run the command "ceph config set mgr mgr/dashboard/redirect_resolve_ip_addr True". I have included much of his email to me below.

I've deployed a Ceph Cluster (v17.2.5) via Cephadm and I was messing around with the MGR Settings. I read through the MGR Dashboard Documentation and came across the "RESOLVE IP ADDRESS TO HOSTNAME BEFORE REDIRECT" Section ( https://docs.ceph.com/en/quincy/mgr/dashboard/#resolve-ip-address-to-hostname-before-redirect ).

However, when I tried to enable the Option I get an error message:

[root@storhost1 ~]# ceph config set mgr mgr/dashboard/redirect_resolve_ip_addr True
Error EINVAL: unrecognized config option 'mgr/dashboard/redirect_resolve_ip_addr'

and when I used "ceph config ls" I also can't find the option:

I also tried a few more greps but I can't find the Option..

Am I missing something here or does this Option no longer exist?
