# Octane upgrade workflow
|
|
|
|
## Prerequisites
|
|
|
|
In this manual we assume that user manages their environment with Fuel 5.1.1 and
|
|
has successfully upgraded it to Fuel 7.0 with the standard procedure.
|
|
|
|
Environments with the following configuration can be upgraded with Octane:
|
|
|
|
- Ubuntu operating system
|
|
- HA Multinode deployment mode
|
|
- KVM Compute
|
|
- Neutron with VLAN segmentation
|
|
- Ceph backend for Cinder AND Glance (Optional)
|
|
- No additional services installed (like Sahara, Murano, Ceilometer, etc)
|
|
|
|
## Install Octane
|
|
|
|
Create archive from this repository with `git archive` command and copy it to
|
|
your Fuel Master host.
|
|
|
|
Unpack Octane tarball to /root/ directory. Change to bin/ directory of Octane.
|
|
|
|
```
|
|
[root@fuel ~]# cd /root/octane/octane/bin
|
|
```
|
|
|
|
Run Octane script to install necessary packages on Fuel master and patch
|
|
manifests and source code of components.
|
|
|
|
```
|
|
[root@fuel bin]# yum install -y git python-pip python-paramiko
|
|
[root@fuel bin]# ./octane prepare
|
|
```
|
|
|
|
## Install 7.0 Seed environment
|
|
|
|
First, pick the environment of version 5.1.1 you want to upgrade. Log in to Fuel
|
|
Master node and run:
|
|
|
|
```
|
|
[root@fuel bin]# fuel env
|
|
````
|
|
|
|
Find the environment you selected for upgrade and remember its ID. We will refer
|
|
to it as `ORIG_ID` below.
|
|
|
|
Use Octane script to create Upgrade Seed environment.
|
|
|
|
```
|
|
[root@fuel bin]# octane upgrade-env <ORIG_ID>
|
|
```
|
|
|
|
Remember the ID of resulting environment for later use, or store it to variable.
|
|
We will refer to it as <SEED_ID> later on.
|
|
|
|
### Upgrade controller #1
|
|
|
|
Choose added controller nodes from the list of unallocated nodes:
|
|
|
|
```
|
|
[root@fuel bin]# fuel node | grep discover
|
|
```
|
|
|
|
Remember the IDs of the nodes and run the following command replacing <NODE_ID>
|
|
with that number:
|
|
|
|
```
|
|
[root@fuel bin]# octane -v --debug install-node --isolated <ORIG_ID> <SEED_ID> \
|
|
<NODE_ID> [<NODE_ID>, ...]
|
|
```
|
|
|
|
This command will install controller(s)with version 7.0 in Upgrade Seed
|
|
environment.
|
|
|
|
### Upgrade State DB
|
|
|
|
State Database contains all metadata and status data of virtual resources in
|
|
your cloud environment. Octane transfers that data to 7.0 environment as a part
|
|
of upgrade of CIC using the following command:
|
|
|
|
```
|
|
[root@fuel bin]# octane upgrade-db <ORIG_ID> <SEED_ID>
|
|
```
|
|
|
|
Before it starts data transfer, Octane stops all services on 7.0 CICs, and
|
|
disables APIs on 5.1.1 CICs, putting the environment into **Maintenance mode**.
|
|
|
|
### Upgrade Ceph cluster (OPTIONAL)
|
|
|
|
Configuration of original Ceph cluster must be replicated to the 7.0
|
|
environment. Use the following command to update configuration and restart
|
|
Ceph monitor at 7.0 controller:
|
|
|
|
```
|
|
[root@fuel bin]# octane upgrade-ceph <ORIG_ID> <SEED_ID>
|
|
```
|
|
|
|
Verify the successful update using the following command:
|
|
|
|
```
|
|
[root@fuel bin]# ssh root@node-<NODE_ID> "ceph health"
|
|
```
|
|
|
|
## Replace CICs 5.1.1 with 7.0
|
|
|
|
Now start all services on 7.0 CICs with upgraded data and redirect Compute
|
|
nodes from 5.1.1 CICs to 7.0 CICs.
|
|
|
|
Following Octane script will start all services on 7.0 CICs, then disconnect 5.1
|
|
CICs from Management and Public networks, while keeping connection between CICs
|
|
themselves, and connect 7.0 CICs to those networks:
|
|
|
|
```
|
|
[root@fuel bin]# octane upgrade-control ORIG_ID SEED_ID
|
|
```
|
|
|
|
### Upgrade compute nodes
|
|
|
|
Select a node to upgrade from the list of nodes in 5.1.1 environment:
|
|
|
|
```
|
|
[root@fuel bin]# fuel node --env <ORIG_ID>
|
|
```
|
|
|
|
Run Octane script with 'upgrade-node' command to reassign node to 7.0
|
|
environment and upgrade it. You need to specify ID of the node as a second
|
|
argument.
|
|
|
|
```
|
|
[root@fuel bin]# octane upgrade-node <SEED_ID> <NODE_ID> [<NODE_ID> ...]
|
|
```
|
|
|
|
Repeat this process until all nodes are reassigned from 5.1.1 to 7.0 environment.
|
|
|
|
## Finish upgrade
|
|
|
|
### Clean up the Fuel Master node
|
|
|
|
Run 'cleanup-fuel' command to revert all changes made to components of the Fuel
|
|
installer and uninstall temporary packages.
|
|
|
|
```
|
|
[root@fuel bin]# ./octane cleanup-fuel
|
|
```
|
