Description Mike Hackett 2018-09-28 18:15:05 UTC

Description of problem:
Release notes state:

Previously, the Red Hat Ceph Storage Dashboard used collectd and Graphite for gathering and reporting on Ceph metrics. With this release, Prometheus is now used for data gathering and reporting, and provides querying capabilities. Also, Prometheus is much less resource intensive.

Ceph-metrics will require an upgrade to get to Ceph-Dashboard with Prometheus. Since all metric data will be lost during this upgrade we are looking from a plan from engineering to document this upgrade process to provide to customers.

Version-Release number of selected component (if applicable):
3.1

Comment 17 Madhavi Kasturi 2018-10-30 07:58:18 UTC

Document - 
https://access.redhat.com/documentation/en-us/red_hat_ceph_storage/3/html-single/installation_guide_for_red_hat_enterprise_linux/#upgrading-a-red-hat-ceph-storage-cluster

Section - If upgrading from Red Hat Ceph Storage 3.0 to 3.1 and using Red Hat Ceph Storage Dashboard, 

Issue: Followed the steps mentioned
1. If the cephmetrics-ansible package isn’t already updated, update it: 
2. Change to the /usr/share/cephmetrics-ansible/ directory. 
3. Purge the existing cephmetrics installation. 

The purging of the cluster is failing at TASK remove containers, as 3.0 cephmetrics did not have contianer deployment.

Playbook fails with error at TASK [Remove containers] 

TASK [Remove containers] ******************************************************************************************************************************************************************************************
failed: [magna012.ceph.redhat.com] (item=grafana-server) => {"changed": false, "item": "grafana-server", "msg": "Failed to import docker-py - No module named docker. Try `pip install docker-py`"}
failed: [magna012.ceph.redhat.com] (item=prometheus) => {"changed": false, "item": "prometheus", "msg": "Failed to import docker-py - No module named docker. Try `pip install docker-py`"}
	to retry, use: --limit @/usr/share/cephmetrics-ansible/purge.retry

Change: Alter the sequence of steps as follows
1. Change to the /usr/share/cephmetrics-ansible/ directory. 
2. Purge the existing cephmetrics installation. 
3. If the cephmetrics-ansible package isn’t already updated, update it: 
Change to --> Update the cephmetrics-ansible package
4. Install the updated Red Hat Ceph Storage Dashboard 

Moving this BZ to assigned.
