To get started click on "Create a resource" to get ready to start deployments of a new instance of EXAScaler of EXAScaler Cloud.
In the search box that appears, type "EXAScaler Cloud" and hit return. For some reason the completions that start to show up do not work as expected.

All required services will automatically start and the filesystem will be mounted and available on all compute clients.
How to upgrade an existing EXAScaler Cloud environment
| Anchor | ||||
|---|---|---|---|---|
|
A software upgrade for an existing EXAScaler Cloud environment is possible by creating a new deployment using a copy of the existing file system.
To upgrade the existing EXAScaler Cloud environment you can use the standard EXAScaler Cloud Azure application by selecting the "Upgrade" value for the "Deployment type" option.
All running instances must be shut down for the existing EXAScaler Cloud environment before performing the upgrade, this is required to ensure data consistency while creating a copy of existing data:

Stop storage server exascaler-cloud-65f1-oss3
Stop metadata server exascaler-cloud-65f1-mds0
Stop management server exascaler-cloud-65f1-mgs0 |
Then launch the standard EXAScaler Cloud Azure application using the Azure Marketplace
➊ Basics step:
- specify your Azure subscription
- new resource group
- region
- and select "Upgrade" value for the "Deployment type" option:
➋ Deployment step: select an existing EXAScaler Cloud deployment:
Base OS image (you can upgrade Red Hat Enterprise Linux to CentOS Linux and vice versa) and availability options:
➌ Security step: specify user name and authentication parameters (you can use user name and authentication parameters other than the existing environment):
➍ Network step: specify network and subnet (you can create a new one) and public IP addresses options:
➎ Management step: you can change the type of management server and the type of management and monitoring targets, but the size of the targets must be the same as in the existing environment:
➏ Metadata step: you can change the type of metadata server and the type of metadata target, but the size of the target must be the same as in the existing environment:
➐ Storage step: you can change the type of storage servers and the type of storage targets, but the number of the storage servers and the number and size of the storage targets must be the same as in the existing environment:
➑ Client step: you can change the type of compute clients and the type of compute targets, but the number and size of the compute targets must be the same as in the existing environment:
➒ Review + create step: at this stage Microsoft Azure checks all selected options against the subscription quota. And we can review and check all the parameters we have chosen before starting the deployment:
