Hi, On which node should we add the "admin socket" parameter to ceph.conf. On the MON, OSD or on what node?
On one of my clients (which is the Ansible node in this case) has the following: [client.libvirt] admin socket = /var/run/ceph/$cluster-$type.$id.$pid.$cctid.asok # must be writable by QEMU and allowed by SELinux or AppArmor Permissions on the folder: 0 drwxrwx---. 2 ceph ceph 40 23 jul 11:27 ceph But /var/run/ceph is empty.
