  • Performing DHCP kexec on discovered hosts

    Authored by: Lukas Zapletal

    Satellite 6.2 introduced PXE-less discovery which is targeted to networks without PXE or DHCP services available. In this workflow, kernel on discovered nodes is replaced (via kexec technology) instead of rebooting. This turns out to be useful feature on PXE/DHCP networks as well.

    To configure kexec on PXE/DHCP enabled network, do the following simple steps.

    Step 1: Verify foreman discovery image version

    Newer version of foreman-discovery-image must be used in order to send required "discovery_kexec" fact. We are planning rebase of foreman-discovery-image package in Satellite 6.2 upcoming errata. In the meantime, it is possible to download upstream version which is based on CentOS 7 rather than Red Hat Enterprise Linux. Series 3.4 are known to work with Satellite 6.2.

    tftp_capsule# cd /var/lib/tftpboot/boot/
    tftp_capsule# wget http://downloads.theforeman.org/discovery/releases/3.4/fdi-image-3.4.1.tar
    tftp_capsule# tar -xvf fdi-image-3.4.1.tar
    

    Step 2: Configure foreman discovery image kernel options

    Satellite will either reboot or kexec discovered node based on presence of special fact called "discovery_kexec". When present and KExec template is associated with given Hostgroup and Operating System, kexec is performed. Reboot is the fallback mechanism if the two requirements are not met.

    In Hosts - Provisioning templates search for "global" string and edit "PXELinux global default" template. In Satellite 6.2 it is possible to directly edit this template, in upcoming version this template must be cloned and Global setting must be changed to use the cloned template instead the default one.

    ONTIMEOUT discovery_upstream
    ...
    LABEL discovery_upstream
      MENU LABEL Foreman Discovery Image 3.4.1
      KERNEL boot/fdi-image/vmlinuz0
      APPEND initrd=boot/fdi-image/initrd0.img rootflags=loop root=live:/fdi.iso rootfstype=auto ro rd.live.image acpi=force rd.luks=0 rd.md=0 rd.dm=0 rd.lvm=0 rd.bootif=0 rd.neednet=0 nomodeset proxy.url=https://CAPSULE_URL:9090 proxy.type=proxy fdi.pxfactname1=discovery_kexec fdi.pxfactvalue1=1
      IPAPPEND 2
    

    Change proxy.url and proxy.type accordingly to point to either Satellite Server or Capsule. Note the options fdi.pxfactname1=discovery_kexec fdi.pxfactvalue1=1 which are required in order to have the "discovery_kexec" fact sent along.

    Now click on Build PXE Default to rebuild pxelinux.cfg/default template. Hosts can be discovered now.

    Step 3: Modify Red Hat KExec template

    Find Red Hat Kexec template, clone it, associate it with requied Operating System and edit its contents:

    <%#
    kind: kexec
    name: Red Hat kexec
    oses:
    - CentOS 4
    - CentOS 5
    - CentOS 6
    - CentOS 7
    - Fedora 19
    - Fedora 20
    - Fedora 21
    - Fedora 22
    - RedHat 4
    - RedHat 5
    - RedHat 6
    - RedHat 7
    -%>
    <%
      mac = @host.facts['discovery_bootif']
      bootif = '00-' + mac.gsub(':', '-') if mac
      append = @host.facts['append']
    -%>
    {
      "kernel": "<%= @kernel %>",
      "initram": "<%= @initrd %>",
    <% if (@host.operatingsystem.name == 'Fedora' and @host.operatingsystem.major.to_i > 16) or
        (@host.operatingsystem.name != 'Fedora' and @host.operatingsystem.major.to_i >= 7) -%>
      "append": "ks=<%= foreman_url('provision') %> inst.ks.sendmac <%= "ksdevice=bootif BOOTIF=#{bootif} #{append}" %>"
    <% else -%>
      "append": "ks=<%= foreman_url('provision') %> kssendmac <%= "BOOTIF=#{bootif} #{append}" %>"
    <% end -%>
    }
    

    The template was designed for DHCP-less environments and it assumes static IP configuration. These "discovery_*" facts are not present, therefore the default template generates "ip=::::::none" Anaconda configuration which leads to System halted. The modified version does not provide static configuration, therefore Anaconda performs DHCP request.

    Make sure to set this template as default one for required Operating Systems.

    Step 4: Verify requirements and provision

    Before provisioning the very first discovered node, show the detail page, expand all facts and search for "discovery_kexec" fact, it should be set to "1". Also make sure the Red Hat KExec template is associated with Operating System.

    Discovered hosts now can be provisioned or auto-provisioned and kexec will be performed instead of reboot.

    Troubleshooting

    On some hardware or VMs, kexec will freeze when discovered node is on the first virtual console (tty1) with the text user interface.

    To workaround this issue switch virtual terminal to tty2 (Alt+F2) before kexecing.

  • Dealing with many network interfaces during host check-ins

    Authored by: Lukas Zapletal

    Satellite 6 comes with powerful host importing capabilities as part of its inventory feature. When a host checks-in via Puppet or subscription-manager, all incoming data, which we call "facts", are parsed. This mechanism is called "fact import".

    By default Satellite 6 extracts networking information such as NICs, MAC and IP addresses making necessary changes to reflect the new state in the inventory database. When an IP address of a registered host changes for example, the same change is applied in Satellite 6 database during fact import.

    This can be problem for hosts with frequently changing interfaces, typically virtualization hypervisors or container hosts. The default behavior in Satellite 6 is safe; new interfaces are added but missing interfaces are never removed. This stems from Puppet behavior when disabled interfaces are not reported via facter which could lead to mis-deletions in the Satellite 6 inventory.

    In these workloads, Satellite 6 will be adding new network interfaces to hosts indefinitely leading to slow performance of host check-ins for both Puppet and subscription-manager. We've seen hosts with thousands of records of invalid network interface inventory data. There are two configuration options to solve this situation.

    First, fact import for NICs can be completely disabled via Ignore Puppet facts for provisioning global setting. When this option is turned on, the IP or MAC address of existing host is never updated automatically. Although the name of this setting implies this only affects Puppet, it also affects subscription-manager import code as well. We will rename this option in the future to match its real meaning.

    This will essentially completely turn off Puppet fact parsing which cannot be used in case hosts are being registered via Puppet and network interfaces are needed, for example to remotely execute scripts. For this case, there is an alternative method to filter out some interfaces from being added or updated in the Satellite 6 inventory via Ignore interfaces with matching identifier global option. By default it is set to:

    'lo', 'usb*', 'vnet*', 'macvtap*', '_vdsmdummy_'
    

    For example to filter out docker network interfaces, 'veth*' would be added to the list. Interface naming conventions are different for virtualization or container technologies like libvirt, vdsm, xen or lxc. What is usually common is some prefix or suffix that can be easily matched using a wildcard syntax. Note the syntax is not a regular expression, but a simple wildcard.

    Satellite 6.2.9 introduced two new settings called Ignore facts for operating system and Ignore facts for subnet which work in a similar way, but are not related to network interfaces.

  • How to share custom repositories across organizations

    Authored by: Lukas Zapletal

    Satellite 6 is strictly a multi-tenant application meaning that every organization gets its own subscription manifest and must select appropriate repositories and sync it. Although the design of Satellite 6 makes sure every single RPM package is downloaded only once across all organization, syncing metadata and publishing and promoting content within many organizations can be time consuming for some specific use cases. The following will work with Satellite 6.2 or newer.

    One use case is a custom Yum repository with EPEL. This type of content can be easily shared across organizations in case there is a need to use latest and greatest EPEL content synced on a daily basis for example. In this case, the recommended way is to create a special organization which we will refer to under the name "SharedContent". It is recommended to give it unique and short label as it will be present in all repository URLs; a good candidate would be "shared".

    Under SharedContent organization new Custom Product and Repository can be created, let's say EPEL product and EPEL7 repository. During creation, the Publish via HTTP option must be checked, or it can be enabled later on in the Repository detail page. For such a large repository like EPEL, it is recommended to use the on-demand download policy and also to customize Satellite 6 squid daemon configuration and cache volume size to handle a large cache .

    After initial synchronization which usually takes longer, the key thing is to find out the URL where the content is being published to. This can be done in the Product - Repository detail page as Published At field. It will be something like:

    http://sat6.host.lan/pulp/repos/shared/Library/custom/EPEL/EPEL7/
    

    The same content is also available under HTTPS but to access content via SSL, a client certificate must be provided. One is available under Organization detail page and it's called Debug Certificate. It is possible to use it to consume the shared content if HTTP is not preferred.

    To consume EPEL content, provisioning templates or puppet manifests need to be updated to use the custom repository. As an example, we will leave here a snippet for Anaconda RHEL kickstart. It is recommended to clone the original template and create a custom one associating it with all Operating Systems and setting it as default:

    ...
    repo --name=epel --baseurl=http://sat6.host.lan/pulp/repos/shared/Library/custom/EPEL/EPEL7/
    ...
    

    For HTTPS URL make sure to use --noverifyssl option or use post scriplet to deploy server certificate and yum configuration after installation when SSL server cert verification is a must.

    Once everything is tested, Sync Plan can be created. It is also possible to create Content Environments or Content Views and leverage content promotion capabilities in the shared organization. That's how any custom repository can be easily shared.

  • Satellite 6.2.10 is released

    Authored by: Rich Jerrido

    Satellite 6.2.10 has been released today. 6.2.10 introduces many fixes based on customer cases and feedback. There is one erratum for the server [1] and one for the hosts [2]. The install ISOs will be updated next week at the earliest.

    Customers who have already upgraded to 6.2 should follow the instructions in the errata. Customers who are on 6.1.x should follow the upgrade instructions at [3].

    PLEASE NOTE: Customers who have received hotfixes should verify the list below to ensure their hotfix is contained in the release before upgrading. Their hotfixes may be overwritten if they upgrade. Please reach out to the Satellite team if you are unsure.

    The list of bugs fixed in in 6.2.10 include:

    • The refreshing of manifests process has been improved with several bug fixes and enhancements such as subscription refreshes and a confirmation dialog. (BZ#1455154, BZ#1455199, BZ#1393580, BZ#1436242, BZ#1266827)
    • The upgrade process will now execute foreman-rake katello:correct_repositories for the user. (BZ#1446713, BZ#1365223, BZ#1375075, BZ#1425437)
    • The subscription status is now consistent across the web UI and CLI. (BZ#1371605)
    • Memory leaks in OpenSCAP and the tasks plug-in have been resolved. (BZ#1432263, BZ#1412307)
    • Updating a content set associated to a pool with very large numbers of entitlements caused Candlepin to run out of memory. Consequently, updating a custom product with a large number of hosts took a long time. This bug has been fixed and Candlepin performance is now improved in the scenario described. (BZ#1435809)
    • Previously, when applying two errata to one thousand hosts the Gofer Agent daemon (goferd) sometimes terminated unexpectedly with a segmentation fault. The code has been improved and goferd no longer fails in the scenario described. (BZ#1418557)
    • Several fixes have been made to remote execution. (BZ#1387658, BZ#1417978, BZ#1422690, BZ#1449830, BZ#1413966, BZ#1390931, BZ#1438601)
    • Capsule synchronization was failing after upgrade for certain library configurations. These cases have been fixed. (BZ#1456446, BZ#1456559)

  • Satellite 5.8 cdn-sync Performance

    Authored by: Grant Gainey

    Introduction

    Red Hat Satellite 5.8.0 comes with a new way to synchronize channel-content from Red Hat: cdn-sync. Unlike satellite-sync, which synchronizes content (i.e. channels, packages, errata, and kickstart trees) from RHN Classic servers, cdn-sync retrieves content from Red Hat's CDN servers (the same source which is used by systems registered via subscription-manager). cdn-sync command attempts to keep option parity with satellite-sync where it makes sense to do so.

    Although Satellite 5.8.0 itself (when running in connected mode) now registers to Red Hat using subscription-manager, clients registered to Satellite continue to use the RHN Classic tooling (e.g. rhn-register).

    While the content-sources differ between satellite-sync and cdn-sync, the goal is to end up with the same results in the Satellite doing the synchronizing. Red Hat is aware of some discrepancies between the two content-sources, and is working on making them consistent. Also, as content is structured differently on CDN, the cdn-sync-mapping package was added, which maps content locations (i.e. repositories with packages or kickstart trees) on CDN to matching channels on Satellites.

    Performance Comparison

    Tests were run concurrently on the same hardware (4 x Intel(R) Xeon(R) CPU E3-1220 V2 @ 3.10GHz, 8 GB RAM) located in same lab. The operating system was a fully updated Red Hat Enterprise Linux 6 Server.

    The tables below show the results from a comparison of sync times for the "Red Hat Enterprise Linux Server (v. 7 for 64-bit x86_64)" repository. The comparison is between the following commands:

    5.8.0 Beta (build 20170330) and the 5.8.0 Release Candidate (build 20170515): cdn-sync -c rhel-x86_64-server-7
    5.6.0 and 5.7.0: satellite-sync -c rhel-x86_64-server-7

    Satellite version time cdn-sync/satellite-sync -c rhel-x86_64-server-7
    Red Hat Satellite 5.6.0 13 hours, 8 minutes, 9 seconds
    Red Hat Satellite 5.7.0 13 hours, 8 minutes, 10 seconds
    Red Hat Satellite 5.8.0 Beta 3 hours, 20 minutes, 28 seconds
    Red Hat Satellite 5.8.0 RC 1 hour, 51 minutes, 7 seconds

    (On the 5.8.0 Beta, sync was without 7.3 kickstart tree, due to a beta bug)

    Conclusion

    Initial sync of a channel takes far less time on Red Hat Satellite 5.8.0 when compared to 5.7.0 or 5.6.0 (around two hours instead of thirteen, assuming a fast connection to cdn.redhat.com). This is primarily the result of the switch to the CDN-based syncing tool cdn-sync, which retrieves content from the content distribution network, fetching content from a source that should be closer to your Satellite Server.

  • Questions and Answers from the February 2017 Satellite Ask-Me-Anything session

    Authored by: Rich Jerrido

    Satellite 6 Ask Me Anything FAQ

    As promised, listed below are the responses to the questions we received in our Feb 2017 Satellite Ask Me Anything session.

    AMA Feb Questions

    January AMA Q&A: https://access.redhat.com/blogs/1169563/posts/2918221

    Next steps: Create 2nd blog post before Tuesday AMA (linking to January Q&A as reference); Later in March, create Satellite 6 Technical FAQ

    Content Views

    Question: Does a composite content view duplicate all content in the content views it contains?
    Answer: No. Content views (and composite views) are merely references to the content on disk. RPM are only stored once on disk. Each content view does having unique yum metadata, but this is measured in the 10s of megabytes.

    Question: What are the best practices for creating a content view?
    Answer: See 2015 - 10 Steps to Build an SOE: How Red Hat Satellite 6 Supports Setting up a Standard Operating Environment https://access.redhat.com/articles/1585273

    Puppet

    Question: Puppet Enterprise only supports integration with Satellite 6 for RHEL 7 or higher puppet masters. Is there any way for RHEL 6 PE users to integrate Satellite with Puppet Enterprise?

    Answer: The integration module is available only for RHEL7 Puppet Masters.

    Question: Is a Continuous Integration/Deployment Workflow possible with Jenkins, r10k and Git possible with Puppet in Satellite 6?

    Answer: Yes. Take a look at the soe-ci to see an example of how one can implement a CI/CD workflow with Satellite 6 + Jenkins

    Question: Is puppet required for provisioning?
    Answer: No

    Install & Upgrades

    Question: I have upgraded my Satellite server from 6.1 to 6.2. However, when viewing my Satellite under access.redhat.com and Subscriptions, it still shows my Satellite Server as version 6.1. Is this serious?

    Answer: It is not serious and you should not be concerned. This is a known bug that will be addressed in future releases of Satellite 6.

    Question: How to automate the installation of RHEL in an environment where dns and dhcp already exists?

    Answer: Simply do not install the DNS and DHCP components on the Satellite.

    Question: We have a number of clients with hostnames that include underscores (''). These clients reported in fine to Satellite 6.1. In order to upgrade to 6.2, I had to delete them in order for the upgrade to be successful. I now find that I cannot add them back. What has changed and why?
    Answer: In Satellite 6.0 and 6.1, there were two definitions of a host, one that was used for provisioning/configuration and another that was used for content/subscription. The content/subscription definition allowed hostnames that were arbitrary, and those could include shortnames & other characters (such as underscores). In Satellite 6.2, one of the major changes was that these definitions were unified, and all hostnames needed to be proper FQDNs. As part of bz1426424, bootstrap.py will allow you to supply an arbitrary hostname when registering that differs from your configured hostname.

    Multi-Org

    Question: We have certain organizations within our organization, which would like to manage their own hosts. How does this work in Satellite 6.x and what's needed to setup multi-org?

    Answer: For each organization, you need to

    • Create a subscription manifest in the Customer Portal
    • Create a new organization in Satellite
    • Import the subscription manifest.

    Question: Is there a way to avoid duplication of sync'd repo data between organizations? We have multiple organizations, and each org seems to need a new copy of repos that are already present in other organizations.

    Answer: RPMs are already deduplicated between organizations. However, each organization needs to 'sync' the repositories that they wish to use in order to get their own copy of them.

    Disconnected Satellites

    Question: My customer is air-gapped from the internet. How can I transfer patches/errata from one Satellite to customer air-gapped Satellite?

    Answer: See Red Hat Satellite 6.2 Feature Overview: Inter-Satellite Sync

    Question: If I have an air-gapped DMZ where I deploy a separate Satellite, will I need to get my subscriptions split as well?

    Answer: Each Satellite will require its own subscription manifest. However, you only need to allocate the subscriptions required to manage each host to the respective Satellite.

    Misc

    Question: What do I need in Satellite 6 to execute remote commands on the guest?

    Answer: SSH Keys need to be setup for each host. Many methods on how to deploy these keys are described in Making systems ready for Satellite 6.2's remote execution

    Question: Any way to extract metadata from Foreman using either hammer or other utilities? I'd like to update our CMDB with this information.
    Answer: Yes, depending on which data you are looking for, this will be accessible via hammer or via the API. Note: hammer can output to CSV, YAML or JSON.

    Question: When should we expect system profile backup feature in Satellite 6?
    Answer: This is currently not planned for an upcoming release of Satellite.

    Question: What do I need to configure our install in order to enable reporting for all hosts under the Host tab?

    Answer: Reporting refers to 'configuration management' reporting. Puppet needs to be installed for this.

    Question: I just applied an errata to a group of systems and it broke and application. How do I figure out what packages were installed if I do not have a profile backup to compare?

    Answer: Each job such as an errata installation submits a background task. You can view these tasks (via Monitor->Tasks) to see which packages were installed.

    Question: We have several VMWare vCenters. What is your recommendation on creating Compute Resources? Should I create 1 Compute Resource for each vCenter?

    Answer: Compute Resources only support a single vCenter, so 1 Compute Resource per vCenter.
