How to fix etcd within a kuberentes cluster?
us flag

I have a bare-metal (kubeadm) kubernetes cluster that's really unstable, and I traced it back to an etcd issue.

From the etcd pod's description I get:

Image: k8s.gcr.io/etcd:3.4.13-0
Liveness: ... #success=1 #failure=8
Startup:  ... #success=1 #failure=24

In the logs startup sequence seems fine (compared to another cluster), then I get a lot of warnings:

Is there a maximum size for an HTTP GET? And if there is a max size, is it determined by the protocol or is it at the discretion of the server?

Increasing Virtual Disk dont show up as unalocated space in Disk Management

In our environment we work with VMware Virtual disk SCSI. When the Windows Servers run out of space we increase the space of the virtual disk. After that, I go in the disk management to increase the disk in the OS, but the unalocated disk space dont show up there. I need to reconnect to the server multiple times to get to see the unalocated space.

Can someone explain this to me and if there is a  ...

download newest build of an artifact using maven in the command line
in flag

All I want at the end of the day is for the puppet-managed servers in our development environment to always pull the latest build of the latest version of whatever application they are running. While maven isn't exactly intended for that, since all the shadowjars live in the same repository as their dependencies, and all come with md5 checksums to compare files that maven already generated, it seemed an  ...

Can't SSH from host to VM through static IP
gb flag

I'm setting a cluster of servers with ubuntu 16.4 VM's to learn about it. As suggested by some tutorials, I set a static ip for each machine besides DHCP one (2 network interfaces). To achieve that I edited /etc/network/interfaces and added the following config:

# The secondary network interface
auto enp0s8
iface enp0s8 inet static
address 192.168.0.210

Server updates out of maintenance window
vn flag

Lately our SQL server had an update out of the maintenance time window. I want to understand a few things:

  1. Do we need to anticipate more updates to our servers which are out of the maintenance time window that we configured?
  2. Was there a way that we could have known about this update? 
  3. Is there a way to make sure all the updates will be in the maintenance window that we configured? 

Thank you! ...

Monitoring Byte Usage of Large MySQL InnoDB Buffer Pools?
jp flag
Vjz

I am trying to monitor the total number of used bytes in a MySQL 5.7 InnoDB Buffer Pool, that can go up to 100GB, using Innodb_buffer_pool_bytes_data but it seems that this status variable is a 32-bit unsigned integer when I query it, so it overflows when bytes go past 2^32.

It seems to be an unsigned long integer internally in MySQL (https://github.com/mysql/mysql-server/blob/5.7/storage/innobase/includ ...

Mail from Teams forwarded to Gmail marked as spam due to DMARC failure

When I write a chat message in Microsoft Teams the receiver gets an e-mail notification on her Office 365 account (receiver@htlvb.at) when she is offline in Teams. The receiver set it up so that all her mails are forwarded to her personal Gmail account (receiver@gmail.com). For normal mails sent to receiver@htlvb.at this works as expected. But all Teams notifications are marked as spam. Google says that ...

cluster-autoscaler simulator in minikube

I have seen examples for the horizontal pod autoscaler (HPA) using minikube (example). However, I'm wondering if there is a similar tutorial to get hands on experience with the cluster autoscaler (CA) with minikube. I don't have access to an actual K8 cluster. Although it seems this should be possible, I haven't found any tutorials on the subject. One reason may be that: as I understand it, the C ...

The Stunning Power of Questions

Much of an executive’s workday is spent asking others for information—requesting status updates from a team leader, for example, or questioning a counterpart in a tense negotiation. Yet unlike professionals such as litigators, journalists, and doctors, who are taught how to ask questions as an essential part of their training, few executives think of questioning as a skill that can be honed—or consider how their own answers to questions could make conversations more productive.

That’s a missed opportunity. Questioning is a uniquely powerful tool for unlocking value in organizations: It spurs learning and the exchange of ideas, it fuels innovation and performance improvement, it builds rapport and trust among team members. And it can mitigate business risk by uncovering unforeseen pitfalls and hazards.

For some people, questioning comes easily. Their natural inquisitiveness, emotional intelligence, and ability to read people put the ideal question on the tip of their tongue. But most of us don’t ask enough questions, nor do we pose our inquiries in an optimal way.

The good news is that by asking questions, we naturally improve our emotional intelligence, which in turn makes us better questioners—a virtuous cycle. In this article, we draw on insights from behavioral science research to explore how the way we frame questions and choose to answer our counterparts can influence the outcome of conversations. We offer guidance for choosing the best type, tone, sequence, and framing of questions and for deciding what and how much information to share to reap the most benefit from our interactions, not just for ourselves but for our organizations.
