[jfut]

It is desirable to be able to provide for el7 and el8.

• https://github.com/ganeti/ganeti/releases/tag/v3.0.0rc1
• Python >=3.6 required
• GHC >= 8.0 required (tested <= 8.8])

[jfut]

Hi, I have built Ganeti 3.0.0.rc1-1 RPM packages to test with el7 and el8. :rocket:

WARNING: Do not use in production environments.

• https://jfut.integ.jp/linux/ganeti/7/testing/
• https://jfut.integ.jp/linux/ganeti/8/testing/
• working branch: https://github.com/jfut/ganeti-rpm/tree/stable-3.0 -> merged to master branch

I have fixed some TODOs and will release a stable version later this month or next month.

Test installation

Please let me know if you have any problems with the test. Thank you for your cooperation.

• el7

Ganeti 3.0.0 RPM for el7 uses python36 (version 3.6.x) packages instead of pyhon (version 2.7.x).

yum --enablerepo=epel install \
  https://jfut.integ.jp/linux/ganeti/7/testing/python36-inotify-0.9.6-14.el7.noarch.rpm \
  https://jfut.integ.jp/linux/ganeti/7/testing/ganeti-3.0.0.rc1-1.el7.x86_64.rpm \
  https://jfut.integ.jp/linux/ganeti/7/x86_64/ganeti-instance-debootstrap-0.16-1.el7.noarch.rpm

You can also update from version 2.x.

yum --enablerepo=epel install https://jfut.integ.jp/linux/ganeti/7/testing/python36-inotify-0.9.6-14.el7.noarch.rpm
yum --enablerepo=epel update https://jfut.integ.jp/linux/ganeti/7/testing/ganeti-3.0.0.rc1-1.el7.x86_64.rpm

• el8

Ganeti 3.0.0 RPM for el8 uses python3 (version 3.6.x) packages.

dnf --enablerepo=epel install \
  https://jfut.integ.jp/linux/ganeti/8/testing/python3-bitarray-0.8.3-3.el8.x86_64.rpm \
  https://jfut.integ.jp/linux/ganeti/8/testing/ganeti-3.0.0.rc1-1.el8.x86_64.rpm \
  https://jfut.integ.jp/linux/ganeti/8/testing/ganeti-instance-debootstrap-0.16-1.el8.noarch.rpm

You can still use various Ganeti OS definitions.

• Ganeti Instance Image (yum)
• ganeti-instance-debootstrap

Haskell(GHC) environment changes

Since Ganeti 3.0.0, the upstream release is built/tested against GHC 8.0 through 8.8.

The GHC versions provided by the EPEL repository for el7 and el8 are as follows:

• el7: 7.6.3-x.y.el7
• el8: 8.2.2-x.y.el8

GHC for el7 cannot build Ganeti 3.0.0 or later. In addition, we have been built and provided RPM packges for many GHC libraries required to build Ganeti, but their version dependencies are complex and very difficult to build.

For those reasons, starting with Ganeti 3.0.0 RPM package, we decided to build using the GHC's official Binary Packages.

Current GHC version to use for build:

• Version 8.6.5
• ghc-8.6.5-x86_64-centos7-linux.tar.xz

Ganeti RPM Changes

• Update to 3.0.0
• Remove BuildRequires: python-ipaddr
• Remove Requires: python-ipaddr
• Remove Requires: bridge-utils
• Use ghc binary package instead of RPMs
• Add %{python3_pkgversion}
• Add the --with-sshd-restart-command option instead of the --with-ssh-initscript option
• Add %global debug_package %{nil}
• Add a check by python unittests(make py-tests) in %check
• Add a check by haskell unittests(make hs-tests) in %check
• Add ganeti-3.0.0-ghc-json-version.patch
• Remove document source files
• Add ganeti-3.0.0-qemu-migrate-set-parameters-version-check.patch (#34)

Please also see the upstream release notes (3.0.0beta1, 3.0.0rc1, and 3.0.0)

Known Issues

• DRBD 8.4 does not support Kernel 4.18.x on el8, so the DRBD disk template cannot be used on el8 yet.

TODO

• [x] Change running user and group (#20)
• [x] Update documents (include #35)
• [x] Build RPM packages using Github Actions (#36)

Hi, I have built Ganeti 3.0.0.rc1-2 RPM packages to test with el7 and el8. :rocket: :rocket:

WARNING: Do not use in production environments.

• https://jfut.integ.jp/linux/ganeti/7/testing/
• https://jfut.integ.jp/linux/ganeti/8/testing/

Important changes

Change running user and group (#20)

Now, ganeti daemons work with the privileges of gnt- users and gnt- groups.

Directories and files in /var/lib/ganeti and /var/log/ganeti are automatically modified to the appropriate permissions by the /usr/lib64/ganeti/ensure-dirs script at startup.

However, to modify the permissions of files in /var/lib/ganeti/queue/archive/, you need to manually execute the following command only once after installing the new package.

# -f, --full-run  Make a full run and set permissions on archived jobs (time consuming)
/usr/lib64/ganeti/ensure-dirs -f

Once you run it, you can just start it normally.

systemctl start ganeti.target

# Optional
systemctl start ganeti-kvmd.service
systemctl start ganeti-metad.service

Migrate qemu-kvm to qmue-kvm-ev

The oldest version of qemu supported by the upstream is qemu-2.11 (Ubuntu 18.04 LTS Bionic). Therefore, it is recommended to migrate qemu-kvm(version 1.5.x) on el7 to qemu-kvm-ev(version 2.12.x). At the moment, Ganeti of the Ganeti RPM Package still works with qemu-kvm, but it will not working in the future.

# Migrate qemu-kvm to qemu-kvm-ev
yum install centos-release-qemu-ev
yum update qemu-*
