ARM64 is become more popular on different markets, but obviously lots of pepople didn't have the hardware platform, and fastmodel is helpful for people to play with ARM64 environment, furthermore, we can run different software platform on it, such as Cloud, HA, Virt and OpenStack.

There is a ramdisk block device (brd), and there is a null multiqueue device (nullblk). The one can do I/O, but doesn't use multiqueue, and the other does multiqueue but cannot do I/O. So the idea is to have a new multiqueue ramdisk block device (ramblk?), which can do both. Would be most useful for testing multiqueue.

Occasionally, new versions of openQA break things. How do you stop that? MORE TESTING! Testing openQA by using openQA to ensure the new versions don't break should be a good example of how openQA can test everything and anything, even itself.

A new Puppet Master will be set up for the openSUSE and public SUSE infrastructure. We will need to move the puppet code from the old server to a new Gitlab instance, deploy it to the new box with r10k, and perform syntax, validation and RSpec testing through ci.opensuse.org

COLO or Coarse Grain Lock Stepping is an High Availability solution that builds on top of Remus, 1. investigate Xen COLO implemention and try to play with it.

I want to use this week to familiar with the SUSE products that i don't have time/chance to participate. For instance, SUSE Cloud, SUSE storage, Docker etc... Just like the presentations in SUSEcon 2015 closing keynote.

Gang(ghe@suse.com) and Eric(zren@suse.com) will do a functional comparison analysis between OCFS2 and GFS2 during this hack week. we will try to setup a GFS2 cluster environment, compare the features and performance with OCFS2,

In Beijing HA server room, we have a Huawei switch with a 10GB bandwith uplink FC port, a iSCSI HBA, a desktop computer, and some SFPs, I will build a 10GB bandwith iscsi server.

• Build zookeeper, mesos-master and mesos-slave on SLE12
• Setup a 3-nodes high-availability cluster (zookepper + mesos-master + mesos-slave run on each node)

With all the changes in the qa_virtauto world, our local CI testing has become rather fragile. This project is all about stabilizing the CI testing and ensuring all builds are fully tested - without manual intervention. :)

openvswitch is used by cloud infrastructure (e.g. OpenStack) and software defined networking stacks, often in conjunction with KVM and Xen compute resources. When creating workloads on KVM compute resources, orchestration services can specify the openvswitch interfaceid and port-profile of the workload's virtual interface(s). E.g. orchestration can create workload configuration containing

GFS2 and OCFS2 are 2 cluster filesystems in linux kernel. We also support GFS2, though most of our customers use OCFS2 as we recommend. Last hackweek, from

L3 bug reproduction often requires becoming the admin for a moment. I'd like to write down some nifty tricks I used to get certain “interesting” system configurations to work.

Task: - Learn Twopence structure

The public cloud is generally not a high availability-friendly environment, with unpredictable I/O latencies and machine stalls, custom tools needed for handling IP assignment etc. The idea with this project is to see if there is any way to leverage the Raft algorithm and booth together with pacemaker_remote for resource management to manage cloud instances and services running in the cloud.

This project aims for enabling FCoE over virtio-net. With that we should be able to run FCoE within a KVM guest, and finally have a 'real' FC host in a KVM guest. This should enable 'real' FC testing, like link failure, multipath operations etc.

While in the past MIPS boards were either low-end PIC32 or found in routers running OpenWRT at most, Imagination themselves have recently released the Creator CI20 board (Ingenic, MIPS32) running Debian. And the Shield Pro (previously iGuardian) kickstarter project (Octeon-III, MIPS64) promises to become a playground for testing KVM hardware virtualization. Porting openSUSE to MIPS will involve setting up an OBS instance linked to Factory (update: done) and cross-compiling a set of packages for an initial bootstrap (update: in progress). Maybe this can be scripted to some degree, as there will be some overlap with the ARM ILP32 port project.

Microsoft released Windows Server 2016 at October, 2016. In the data center edition, it released Storage Spaces Direct features for SDS/HCI market. What are those new features looks like? Proxmox a open-source company based in Vienna, which provides a linux cluster stack for kvm/lxc environment. What HA Storage related new ideas inside?

When doing the backport, I sometimes spend some time to check if the commit comes from a patch series and list all commits of a patch series. So I'd like to create a tool for doing this quickly.

As live migration is widely used in many scenarios nowadays, spend one week time to study it and try to improve its efficiency, e.g. seamlessly migrate with less downgrading the guest. Another challenging part is memory migration, as it involves the dirty memory's detection, record and copy.

Customers are using complex storage stacks such as LVM over dm-crypt over MD RAID over multipath over iSCSI and FC with LOTs of LUNs, and we're facing problems in that area which are usually very hard to reproduce. It's also hard to guard against regressions. Being able to quickly and reliably set up VMs with various types of storage / multipath is a key part of testing multipath. It's doable, but cumbersome and has a steep learning curve. I want to create easy-to-understand manual recipes plus scripts that are both easy to understand / customize and deploy.

0 Background This will be a verification test for Intel i915, code has been merged into kernel 4.16 and qemu 2.12, will provide a setup manual as output.

This is somehow related with our team's work(https://fate.suse.com/323437), We want to write a set of restful API for any components in HA product stack use to control the cluster.

The result for xfstests in osd seems always red[1], but actually it's only a few test fail in a group(around 1/50). If we want to keep use openQA to handle those test, we need some enhancement for that. Try to enhancement test result to make it shows in a better way. - Make more reasonable group for those test

In the other day, there were questions about to migrate high availability solution into OpenStack. With that context, there is no question to run the critical pacemaker and corosync processes inside the cloud. There is no difference between VMs and bare-metals in regarding to the dependency management system for both systemd and pacemaker, which is quit different than the situation of the container world. However,

In the past, some customers ever complained that OCFS2 file system performance went down when listing a big directory (e.g. include 400k files). According to my preliminary investigation, this performance problem is related to file system block allocation algorithm. Then, I want to look at the current mainstream file systems (e.g. EXT4, XFS, etc) block allocation algorithms in this hack week, compare and analysis these algorithms advantages/disadvantages.

INSTRUCTION: A remote reminder connected this server with WIFI module(Maybe not just a reminder :smile: ).

https://mycroft.ai/ Mycroft is the name of a suite of software and hardware tools that use natural language processing and machine learning to provide an open source voice assistant.

Since my mailbox has migrated to office365 mailbox a couple of weeks ago, I tried to optimize my tool chain to sync my mail and calendar and integrate to the gnome-shell (calendar, notification). So far I am comfortable with such a set and gonna use 2-3 hours in hackweek to summarize the practice of combining the following tools in written format: mutt, a small part of evolution process (for calendar sync), mailnag, mailnag gnome-shell-extension, tuning of gnome notification (understand the notification in full screen), trayicon plus.

Project Description

In the past year we've found ourselves in the middle of a pandemic, we merged two awesome companies together, and we have completely changed the trajectory of SUSE and Rancher. This project is intended to transfer knowledge of SUSE to Rancher and Rancher to SUSE for those who may be challenged with time and resources to try new things. This gives us a chance to explore other uses for Kubernetes all while taking advantage of older equipment (for use as workers) we may have to spare.

Project Description

Overall: Existing NFS-HA Consulting solution exists (for SLES15 SP1 and SP2+) and is in production at customers. Goal is to improve this solution, enhance the documentation and make it more robust.
