This guide presents the complete walk-through how to upgrade OnApp Cloud v4.3 to the v5.0 for the cloud configuration where all servers are CloudBooted except Control Panel server. Please follow the complete procedure of the upgrade process. All packages (Control Panel, CloudBoot, Compute resources) must belong to the same major version to ensure the best performance of your cloud.

Important Notes


 

  1. You must be running the latest patch of OnApp 4.3 version to upgrade to 5.0 version. If you are using an earlier version, please upgrade to 4.3. first.
  2. Check the Activity Log in your OnApp CP dashboard if there are no transactions running in your cloud. If so, wait until all transactions are complete.
  3. Make sure no Control Panel files are open for editing under the root user account.

  4. If you are using a third-party billing platform, please ensure that this is compatible with OnApp 5.0 before proceeding with the upgrade! The latest WHMCS modules can be found here.

  5. If you are using WHMCS modules, make sure to update the PHP Wrapper after you update OnApp Cloud. Download the latest wrapper.

  6. Be aware that from now on, OnApp Licensing has a standalone client.Use only 443 port to connect from Control Panel to licensing server.
  7. We strongly recommend that you test all your custom scripts before upgrading your production environment.

  8. Be aware that OnApp does not support UEFI on static compute resources. You should disable UEFI on your compute resources before installing OnApp.

  9. If you are using Integrated Storage with caching, please contact support before upgrade.

  10. Update of packages using the default repositories (base, update etc.) is no longer applicable as centos.org has stopped the support of CentOS 5.x.. You should switch boxes running on CentOS 5.x., to the so called Vault repositories. At least, it will give a possibility to install packages, which are necessary because of different dependencies.

Drives assigned for use by Integrated Storage are identified using a disk signature that is generated using SCSI page query mechanism to the device. Please note that disk signatures may change across different kernel versions following an upgrade and reboot. If this occurs, go to the compute resource edit page to re-identify and select the correct drives. Please contact support if you have any concerns regarding this operation.

Default Bonding Mode changed to IEEE 802.3ad Dynamic link aggregation

The OnApp Integrated Storage uses IEEE 802.3ad dynamic link aggregation as default bonding mode for SAN Network. This requires your switch configured to work in LACP mode. This setting will be applied when making changes to the Cloudboot Compute Resource. Please edit each of your Cloudboot Compute Resource setting that are using bonding to the desired one and press Save.

Upgrade Control Panel Server


 

  • CP installer for Installation and Upgrade contains a new -D option enabling to avoid OnApp database dumping during the install/upgrade.
  • To increase the cloud performance we recommend setting RUBY_GC_MALLOC_LIMIT parameter in custom configurations to 16 millions. For more information on RUBY_GC_MALLOC_LIMIT parameter, refer to Ruby’s GC Configuration and Garbage Collection articles.

  • Installer output is redirected to ./onapp-cp-install.log

  • All installer critical errors are in /var/log/messages

  • Custom values must be set before the installer script runs.
  • You may wish to reboot your Control Panel server to take advantage of a new kernel if it is installed. It is not required immediately as a part of the upgrade process though.
  • If you face the problem with viewing the maps on VS/Smart/Application server creation wizard (Locations step), refer to the Add Google Map API Key document.

 

To upgrade your Control Panel server:

  1. If you are using a remote RabbiMQ server, make sure the onapp user on the Control Panel has SSH access to that remote server:

    su onapp
    ssh root@<ip addrees>


  2. Stop the Monit service:

    # service monit stop
  3. Run the following command from the CP server to stop the OnApp service:

    service onapp stop
  4. Download and install the latest OnApp YUM repository file:

    bash#> rpm -Uvh http://rpm.repo.onapp.com/repo/onapp-repo-5.0.noarch.rpm
  5. Upgrade OnApp Control Panel installer package:

    bash#> yum update onapp-cp-install


  6. Update your server OS components (if required):

    bash# /onapp/onapp-cp-install/onapp-cp-install.sh -y
  7. (Optional) If you need some custom Control Panel configuration, set the values before the installer script runs.

    --noservices

    Do not start OnApp services: monit, onapp and httpd
    Please note, crond and all OnApp's cron tasks remain running. They could be disabled by stopping crond service manually for your own risk.

    -Ddo not make database dump, and make sure it is disabled in the cron and not running at the moment
    -hprint this info

    You may wish to reboot your Control Panel server to take advantage of a new kernel if it is installed. It is not required immediately as a part of the upgrade process though.

    Customers running vCloud integration pay attention that upgrade process can take some time, as vCloud and OnApp synchronization is running along with OnApp upgrade.


    Perform the following steps if you plan to deploy Accelerator. Otherwise skip.


  9. If you plan to configure an Accelerator, run the following command:

    • For all compute resources:

      rake hypervisor:messaging:configure
    • For certain compute resources only:

      rake hypervisor:messaging:configure['11.0.50.111 11.0.50.112']

      To perform the configuration for a number of compute resources, separate their IPs with a space.

    The command above runs on compute resources that are online. If some compute resources are offline, you should run the command again when they are online.

    The rabbitmq_host parameter in the on_app.yml file should contain the real IP address of the server with RabbitMQ installed. The rabbitmq_host parameter should not be set to 'localhost' or '127.0.0.1'.

    The server with RabbitMQ installed should be available from the compute resources.



    For information on manual configuration for Accelerator, refer to RabbitMQ Configuration for Accelerator.

 

Upgrade CloudBoot Packages




  • Create a backup of the /tftpboot directory in case storage packages rollback will be needed.
  • If you are updating to the OnApp 5.0 Patch 4 CloudBoot Update, note that NIC naming has been changed from MGT to mgt in this update. This improvement affects CloudBoot compute resources that have custom scripts with advanced networking configuration including MGT NIC manipulations. You need to change 'MGT' to 'mgt' in the compute resource custom scripts during the update, if 'mgt' NIC manipulations are performed there.

To upgrade the OnApp Storage packages:

  1. Upgrade the repo:

    CP_host#> rpm -Uvh http://rpm.repo.onapp.com/repo/onapp-repo-5.0.noarch.rpm
    
  2. Upgrade the packages:

    CP_host#> yum update onapp-store-install
  3. Run the script:

    CP_host#> /onapp/onapp-store-install/onapp-store-install.sh

    Be aware that the disk-less nodes password is the root password for the CloudBoot compute resources. By default it is blank.

    When run in the interactive mode, enter the required information.

Upgrade CloudBoot Backup Servers



Make sure to update CloudBoot packages on your Control Panel server before proceeding to the upgrade of CloudBoot backup servers.


CloudBoot backup servers are CloudBooted KVM compute resources that can be be used as backup servers. The CloudBoot backup server upgrade procedure is almost the same as the CloudBoot compute resource upgrade. Follow the instructions provided in this section to upgrade CloudBoot backup servers in your cloud.

Once you have upgraded the CloudBoot dependencies, you have to reboot your Cloud Boot compute resource to update the Cloud Boot RPM. You do not need to perform any backup server upgrade operations using console.

To do so:

  1. Go to your Control Panel Settings menu.

  2. Click the Compute resources icon.

  3. Click the label of the CloudBoot compute resource the backup server is based on.

  4. On the compute resource details screen, click the Actions button, then click Reboot Compute resource.

  5. A new screen will open asking for confirmation before reboot:

    • Are you sure you want to reboot this compute resource? Confirm that you want the compute resource to reboot.

  6. When you're certain you want to proceed with the reboot, click the Reboot button.

  7. Repeat these steps for all CloudBoot backup servers in your cloud.

  8. Once all are rebooted, proceed to CloudBoot compute resources upgrade.

Upgrade CloudBoot Compute Resources


Simple RebootThis method is the simplest method technically. It also ensures all tools are updated. However, it will result in some limited downtime (its duration depends on how many virtual servers are running on each compute resource).
Migrate and rebootThis method involves migrating all virtual servers off each CloudBoot compute resource in turn. The compute resource can then be safely rebooted, picking up the upgraded Integrated Storage and CloudBoot packages. Virtual servers that do not support hot migrate will have to be stopped.

In case you have applied any custom configuration to your CloudBoot servers, it is recommended to recheck that this customization does not break new cloud boot image version. For this, reboot a compute resource and run Storage Health Check and Network Health Check. Make sure that Vdisks hosted on a compute resource are redundant and healthy before rebooting a CloudBoot compute resource.

If you are using Integrated Storage with caching, please contact support before upgrade.


Simple Reboot

Follow the below procedure to upgrade the CloudBoot compute resources with reboot:
 

1. Upgrade CloudBoot Packages.
2. When the CloudBoot packages upgrade is complete, stop all virtual servers which reside on the CloudBoot compute resources.

3. Reboot all CloudBoot compute resources.

Once the compute resources are booted, the upgrade is complete. Before starting all Virtual Servers please ensure that the diagnostics page does not report any issue. In case of any issue, please press repair button to resolve it, then continue with starting Virtual Servers.


Note that virtual servers cannot be stopped simultaneously, but must be stopped in sequence. This can result in considerable downtime if there are a large number of virtual servers.

Migrate and reboot

Use this procedure if you prefer migrating all virtual servers to another compute resource and conducting overall upgrade of your CloudBoot and Integrated Storage. Virtual servers that do not support hot migrate will have to be stopped.

Once you have upgraded the CloudBoot packages, you have to reboot your CloudBoot compute resources to update them.

To do so:

  1.  Run the following command from the Control Panel server terminal to display the list of compute resources with their IP addresses. Make a note of the list of IPs:

    CP_host#> liveUpdate listHVs 

    This command will also show whether compute resources are eligible for live upgrade.

    If the command liveUpdate is not available then it may be located in the sbin directory instead (cd /usr/local/sbin).

  2. Run the following command for every compute resource:

    CP_host#> liveUpdate updateToolstack <HV IP Addr> 

    Once all the toolstacks are updated run the following command for every compute resource: 

    CP_host#> liveUpdate refreshControllers <HV IP Addr>

    Wait several minutes for all degraded disks to come to synchronized state. The synchronization will take approximately three minutes for each compute resource.

    After each controller restart, check for any issues on the backup server (or on one Compute resource from each zone):

    1. Log on via SSH to the backup server (or Compute resource).
    2. Run getdegradednodes from the SSH console.
    3. Run getdegradedvdisks from the SSH console.

  3. Migrate all the virtual servers from the CloudBoot compute resource to another compute resource. Follow the instructions described in the Migrate Virtual Server section of the Admin guide to migrate virtual servers.
  4. After that, go to your Control Panel Settings menu.
  5. Click the Compute Resources icon.
  6. Click the label of the CloudBoot compute resource you have migrated all VSs from.
  7. On the compute resource details screen, click the Actions button, then click Reboot Compute resource.

    Rebooting a compute resource assigned to a data store with a single replica (single-replica compute resource) or degraded virtual disks may result in data loss.


  8. A new screen will open asking for confirmation (via two check boxes) before reboot:

    • Stop all virtual servers that cannot be migrated to another compute resource? Check this box if you want VSs that cannot be migrated to be powered off. When a compute resource is scheduled for a reboot, OnApp will first attempt to hot migrate all VSs it hosts. If hot migration is not possible for a VS, OnApp will attempt to cold migrate that VS. With this box checked, if cold migration fails, the VS will be stopped so the reboot may proceed. If you don't check this box, OnApp will attempt to hot and then cold migrate all VSs hosted by the compute resource being rebooted – but will stop the migration process if any VS cannot be migrated.
    • Are you sure you want to reboot this compute resource? A simple confirmation to confirm that you want the compute resource to reboot.

      Before the reboot, please ensure that all vdisks are fully synced and redundant. If some of them are not fully synced, the virtual server, that is owner of a degraded (or non-redundant) vdisk, can loose access to the vdisk. It can be manifested as IO errors during writes or reads to/from the vdisk inside the virtual server.

  9. When you're certain you want to proceed with the reboot, click the Reboot button.
  10. Once the compute resource is booted, repair the disk that were degraded during the reboot.

    1. Make sure no disks are out of sync. To do so, check the Diagnostics page in CP at Dashbord > Integrated Storage > Compute zonelabel > Diagnostics. Alternatively, log into a compute resource and run the command below: 

      HV_host#> getdegradedvdisks
    2. Repair all the degraded disks before proceeding to the upgrade process. To do so, log in to your CP and go to Integrated Storage > Compute zonelabel > Diagnostics page. Alternatively, run one of the following commands:

      HV_host#> onappstore repair uuid=
      HV_host#> parallelrepairvdisks
  11. Repeat these steps for all CloudBoot compute resources in your cloud.

Configuration for Accelerator

Perform the following steps for your Cloudboot compute resources if you plan to deploy Accelerator.

  1. Run the following command on the CP server:

    • For all compute resources:

      rake hypervisor:messaging:configure
    • For certain compute resources only:

      rake hypervisor:messaging:configure['11.0.50.111 11.0.50.112']

      To perform the configuration for a number of compute resources, separate their IPs with a space.

  2. The command above should  be run after every reboot. However, you can avoid the necessity to run the command repeatedly after every reboot by coping the following information (using your parameters) from /home/mq/onapp/messaging/credentials.yml to the custom config:

     echo "---
    host: 10.0.50.4  # RABBITMQ SERVER IP/FQDN
    port: 5672      # RABBITMQ CONNECTION PORT(default: 5672)
    vhost: '/'
    user: accelerator-example # RABBITMQ USER NAME
    password: 'e{y31?s8l' #RABBITMQ ACCESS PASSWORD
    queue: 'hv-10.0.50.102' # hv-[IP Address of Compute Resource]
    exchange:
      name: 'acceleration'
      type: 'direct'
      durable: True" > /home/mq/onapp/messaging/credentials.yml
    chown -R mq:mq /home/mq
    service onapp-messaging restart

    For information on manual configuration for Accelerator, refer to RabbitMQ Configuration for Accelerator.


Local Read Policy



Enabling Local Read on a compute zone ensures that the locally stored copy of the data will always be used for reads. This significantly reduces read latency and improves overall storage performance by reducing load on the SAN network. However, in order to use this policy every compute resource must have sufficient physical drives to be able to store the number of stripes specified in the data store. E.g. in a 2R4S data store there must be at least 4 physical disks on the compute resource to use local read.


Changes to Local Read Policy Enforcement


 

Originally, when this policy was introduced OnApp did not enforce the requirement for the minimum number of drives. Consequently, some users who set the policy having insufficient drives may see the following error message:

 

Fatal: OnApp::Actions::Fatal Storage API Call failed: {"result"=>"FAILURE", "error"=>"Local reads have been enabled on the zone - members required per host: 4, required hosts: 2, available hosts: 0"}

The solution is to either add additional drives to that compute resource and then add them to the data store or to disable read local.


Getting support for your upgrade

You can use the information in this document to perform your own upgrade to the 5.0 version of the OnApp Cloud. However, if you have a full OnApp Cloud license, you are entitled to free upgrade support from the OnApp Support team.

If you would prefer to have the Support team perform the upgrade for you, just raise a ticket in the normal way. Please be aware, however, that there may be a queue! For help with your upgrade, visit the OnApp community forum: http://forum.onapp.com.
