5.9.6.2.2. Terminating Access With umount , all access to the disk drive must be terminated. For partitions with active file systems on them, this is done using the umount command. If a swap partition exists on the disk drive, it must be either be deactivated with the swapoff command, or the system should be rebooted. Unmounting partitions with the umount command requires you to specify either the device file name, or the partition's mount point: A partition can only be unmounted if it is not currently in use. If the partition cannot be unmounted while at the normal runlevel, boot into rescue mode and remove the partition's /etc/fstab entry. When using swapoff to disable swapping to a partition, you must specify the device file name representing the swap partition: If swapping to a swap partition cannot be disabled using swapoff , boot into rescue mode and remove the partition's /etc/fstab entry.

Commands:
umount /dev/hda2 umount /home
swapoff /dev/hda4

16.6. virt-rescue: The Rescue Shell This section provides information about using the rescue shell. 16.6.1. Introduction This section describes virt-rescue , which can be considered analogous to a rescue CD for virtual machines. It boots a guest virtual machine into a rescue shell so that maintenance can be performed to correct errors and the guest virtual machine can be repaired. There is some overlap between virt-rescue and guestfish. It is important to distinguish their differing uses. virt-rescue is for making interactive, ad-hoc changes using ordinary Linux file system tools. It is particularly suited to rescuing a guest virtual machine that has failed . virt-rescue cannot be scripted. In contrast, guestfish is particularly useful for making scripted, structured changes through a formal set of commands (the libguestfs API), although it can also be used interactively.

Chapter 8. Defining deployment details To automate the deployment of Red Hat Hyperconverged Infrastructure for Virtualization using Ansible, you need to define your deployment in the following configuration files. These files are created on the hyperconverged node and establish SSH public key authentication with itself and other nodes in the cluster. gluster_inventory.yml An inventory file that defines the storage volumes and their layout as Gluster volumes. single_node_gluster_inventory.yml An inventory file for single node deployment that defines the storage volumes and their layout as Gluster volumes. he_gluster_vars.json A variable file that defines a number of required values for deployment. Procedure Create backup copies of the example configuration files. For 3 to 12 nodes deployment, use the following commands to create the backup copies: For single node deployment, use the following commands to create the backup copies: Define your deployment in a gluster_inventory.yml for a 3 to 12 nodes deployment or in single_node_gluster_inventory.yml file for a single node deployment. Use the example gluster_inventory.yml file to define your deployment. A complete outline of this file is available in Understanding the gluster_inventory.yml file Define deployment variables in a he_gluster_vars.json file. Use the example he_gluster_vars.json file to define the required variables. A complete outline of this file is available in Understanding the he_gluster_vars.json file Encrypt the he_gluster_vars.json file and specify a password. The required variables in he_gluster_vars.json include password values, so it is important to encrypt the file to protect the password values. Enter and confirm a new vault password when prompted. This password is required when you deploy Red Hat Hyperconverged Infrastructure for Virtualization using the process in Executing the deployment playbook . See Working with files encrypted using Ansible Vault for more information.

8.43. fence-virt 8.43.1. RHBA-2013:1601 - fence-virt bug fix update Updated fence-virt packages that fix two bugs are now available for Red Hat Enterprise Linux 6. The fence-virt packages provide a fencing agent for virtual machines as well as a host agent, which processes fencing requests. Bug Fixes BZ# 883588 The respective gzip files for the fence_virt(8) and fence_xvm(8) manual pages were previously created with executable permissions for everybody, which is incorrect. This has been fixed and these files are now properly created with 644 permissions. BZ# 903172 A bug in the fence_virt fencing agent could cause the agent to fail listing the virtual machines that could have been fenced by the fence_virtd daemon using the serial channel within a virtual interface. This happened when the virtual machine had been started or live-migrated after starting the fence_virtd daemon on the cluster node. The bug has been fixed and fence_virt now lists virtual machines as expected in this scenario. Users of fence-virt are advised to upgrade to these updated packages, which fix these bugs. Before applying this update, make sure all previously released errata relevant to your system have been applied.

13.2. Types The main permission control method used in SELinux targeted policy to provide advanced process isolation is Type Enforcement. All files and processes are labeled with a type: types define a SELinux domain for processes and a SELinux type for files. SELinux policy rules define how types access each other, whether it be a domain accessing a type, or a domain accessing another domain. Access is only allowed if a specific SELinux policy rule exists that allows it. The following types are used with dhcpd : dhcp_etc_t This type is mainly used for files in /etc , including configuration files. dhcpd_var_run_t This type is used for the PID file for dhcpd, in /var/run . dhcpd_exec_t This type is used for transition of DHCP executable files to the dhcpd_t domain. dhcpd_initrc_exec_t This type is used for transition of DHCP executable files to the dhcpd_initrc_t domain. Note To see the full list of files and their types for dhcp, run the following command:

Chapter 6. April 2024 6.1. Cluster info Customers noticed that cloud and OpenShift costs in cost management do not always match the data that is in the cloud provider's console. Most of the time, this discrepancy is because there is a missing integration between the Hybrid Cloud Console and either the OpenShift cluster, or the cloud customer account. This missing integration creates discrepancies in billing and cluster data. To help solve this discrepancy, we added two new views in the OpenShift details page of cost management: The Cluster information view shows details about your cluster such as the cluster ID, the Cost Management Metrics Operator version and if there is an update available, and links to your integrations. The Data details view shows your data processing states. These states inform you if data is already processed, is currently processing, or has errors. If you have a linked cloud integration for a cluster, it also displays the processing states for supported clouds. 6.2. Tag mapping You can now unify your tags by mapping ones that have similar or related meanings. This functionality offers greater flexibility and control over how you categorize and track your resources. Tag mapping reduces complexity, helps you have accurate reporting and analysis, and enhances consistency across your resources. For example, imagine that you are tracking your environment spending across different platforms, each with its own naming conventions: Platforms: GCP OpenShift AWS Variations in your key values: env environment Environment With the tag mapping feature, you can seamlessly convert these key values under a single expected key, such as environment , to ensure that you are consistent in tracking your spending. To learn about tag mapping, see Enabling and creating a tag mapping .

Chapter 1. Overview of the API Designer Red Hat Fuse on OpenShift provides API Designer, a web-based API editor, that you can use to design REST APIs that comply with the OpenAPI specification (versions 3 or 2), a vendor-neutral and portable open description format for API services. API Designer is a "light" version of the Apicurio Studio open source project ( https://www.apicur.io/ ). This means that your API Designer sessions are stateless and you must save your API definition as a JSON file at the end of each session. You can also use API Designer to generate a preliminary Fuse project based on a REST API definition. In your Fuse development environment, you can then complete the project's Camel routes and build the project. Finally, you can deploy the resulting REST service on Fuse on OpenShift. Here is an overview of how you can use API Designer to incorporate REST APIs in your Fuse on OpenShift application solution: Add API Designer as a service to your OpenShift project. In API Designer: Create an API definition with API Designer. Save the REST API definition as a JSON file to your local file system. You can save your API definition at any point during your editing session, even if the API definition is not complete. Upload an API definition to API Designer. Generate a Fuse Camel project based on the current REST API definition. API Designer provides a downloadable zip file that contains a complete Maven project. In your Fuse development environment, complete the skeleton implementation provided by the generated Fuse project. Build and deploy the Fuse application to OpenShift. (Optional) Integrate the Fuse application with Red Hat 3scale API Management, using the 3scale service discovery capability to find and configure your Fuse application.
