I'm trying to follow the directions in ceph-ansible for having it automatically set up the crush map. I've also looked at https://access.redhat.com/documentation/en-us/red_hat_ceph_storage/4/html/in... But.. my setup isnt working. ansible complains about: [WARNING]: While constructing a mapping from /etc/ansible/hosts.yml, line 5, column 9, found a duplicate dict key (hostA2). Using last defined value only. Could anyone explain what I'm doing wrong, please? Here's the relevant hosts.yml snippets all: children: osds: hosts: hostA1: osd_crush_location: host: 'hostA1' chassis: 'hostA' root: 'default' hostA2: osd_crush_location: host: 'hostA2' chassis: 'hostA' root: 'default' -- Philip Brown| Sr. Linux System Administrator | Medata, Inc. 5 Peters Canyon Rd Suite 250 Irvine CA 92606 Office 714.918.1310| Fax 714.918.1325 pbrown@medata.com| www.medata.com
