SysEleven Stack Cinder API issues in Region CBK

SysEleven Status — Wed, 27 Feb 2019 15:45:00 +0000

Currently we are facing issues with the SysEleven Stack API. We have noticed, that when creating a new Cinder Volume, it will be in "error" state immediately. Cinder volumes that have been created before already are not affected. We are working on a solution and keep you informed.

SysEleven Stack API issues

SysEleven Status — Mon, 18 Feb 2019 13:22:00 +0000

We observed an elevated rate of errors, creating local storage virtual machines (L1.* flavor). Engineers are now looking into the problem and we will keep you informed here. **UPDATE 15:45**: Creating L1.* virtual machines currently requires unusual amounts of disk space on the hypervisors. The elevated error rate was because not enough space was left, for short amounts of time. Our engineers have resolved this issue for now, and are still working on a permanent solution. Please contact us at cloudsupport@syseleven.de if you are still encountering any issues.

SysEleven Stack API issues in Region DBL

SysEleven Status — Tue, 12 Feb 2019 23:12:00 +0000

Currently we are facing issues with the SysEleven Stack API in the DBL Region. We are working on a solution and keep you informed. The outage only affects spawning new virtual machines or changing existing resources. We apologise for any inconveniences. **UPDATE 00:30**: We have identified the cause of the API issues in DBL and resolved the issues for most API operations.

SysEleven Stack: Long wait time when creating Local SSD Storage servers in all regions

SysEleven Status — Mon, 11 Feb 2019 09:21:00 +0000

Currently it will take a long time to create servers with the Local SSD Storage (L1.*) flavors. The wait time increases linearly to Local SSD Storage capacity of the chosen flavor. Eventually, creating the server will succeed. This is due to a mitigation we put in place that solves sporadic performance problems, when a virtual machine has been created or deleted. We are right now working on a better mitigation, that will not affect creating servers. The issue only affects spawning new virtual machines with the L1.* flavor (Local SSD Storage). We apologise for any inconveniences. **UPDATE 2019-02-13:** The issues are fully resolved now. Creating and deleting Local SSD Storage instances will only take a few seconds now, and the time for creating and deleting VMs is constant, no matter what disk capacity.

MetaKube partial outage

SysEleven Status — Sat, 12 Jan 2019 11:00:00 +0000

Root cause: We created a oauth service with dex to authenticate our web applications against. Dex writes all of the session information into the etcd cluster. Due to a misconfigured monitoring we created over 500000 sessions in the etcd cluster. The database size grow from about 300MB to 700MB. That slowed down all cluster operations. During the whole incident customer applications were not affected, the MetaKube dashboard including cluster creation were regularly not working correctly when one of the master apiservers ran out of memory.

SysEleven Stack Neutron API issues in Region DBL

SysEleven Status — Wed, 02 Jan 2019 10:00:00 +0000

We were facing issues with the SysEleven Stack Neutron API between Dec 29th 2018 and Jan 2nd 2019. Some Neutron API requests were slow, and a few requests might have timed out and failed. The reason was an almost-out-of-memory situation in the software of one of the three SDN controllers. The problem was fixed at 11:26 CET on Jan 2nd 2019. Network connectivity of VMs were not affected by this issue. We apologise for any inconveniences.

SysEleven Stack issues in region DBL

SysEleven Status — Tue, 04 Dec 2018 09:55:00 +0000

Some Instances in DBL were unreachable between 10:55 and 11:03. **Update 11:05**: The problem appears to be currently resolved but we are still investigating to understand the root cause. **Update 11:45**: All Instances in our DBL region were affected by a loss of network. The outage was caused by a maintenance command issued on one isolated and empty compute node that unexpectedly affected all hypervisors in the whole cluster. It raised the log level which led to our SDN agents to be overwhelmed by traffic. We will conduct a post-mortem to find ways to prevent that error from happening again.

SysEleven Stack issues in region CBK

SysEleven Status — Mon, 15 Oct 2018 10:05:00 +0000

Today we were facing issues with the distributed file system, a core component of the SysEleven Stack. **Affected times for the region CBK** 13:12 – 13:17 (MESZ) 14:32 – 14:37 (MESZ) **Affected times for the region DBL** 12:05 – 12:15 (MESZ) 12:51 – 13:00 (MESZ) 13:50 – 14:00 (MESZ) During these times it was possible that virtual machines did not respond due to IO wait. It might also have affected creating virtual machines and cinder volumes. We will keep you informed and apologise for any inconveniences. **UPDATE 16:20** We identified that regular maintenance work on storage nodes (reboots) have indirectly caused this incident.

SysEleven Stack API issues in Region DBL

SysEleven Status — Tue, 02 Oct 2018 11:40:00 +0000

Currently you may experience troubles with the network API . Spawning and deleting instances or other network resources is not possible. If you experience any unexpected behaviour don't hesitate to contact us. We apologise for any inconveniences. **UPDATE 22:45** We have identified and resolved the networking API troubles. We found a bad entry in the network state database of our SDN software, that caused a cascading failure: Internal locks could not be acquired anymore, which caused the API errors, which in turn caused networking troubles during live migrations in a small number of virtual machines. We now understood the root cause and will post more information on actions we will take to prevent this from happening again once we conducted the post-mortem. **UPDATE 15. October** We are currently working the following action points: * We identified and are working to resolve the root cause in our SDN software * We will improve the monitoring of our networking APIs, to identify and correlate future troubles earlier * We will improve monitoring of virtual machine port binding of our SDN software, so we can identify and fix troubled VMs faster in the future
