What is the best way to clone a set of software RAID 1 disks?

Here's the thing: One of my friends has a server with software RAID-1 with a set of two disks. The task at hand is simple: clone the disks into another set of two empty disks.

He is running CentOS, I don't know which version though.

Now, I know that the most straightforward way is to manually fail one of the drives, put an empty drive on its place and let it rebuild. Then fail the other old drive, p ...

Does "docker swarm leave" sends any kind of SIGNAL to the containers to give them a chance to gracefully shutdown?
us flag

I wasn´t able to find an answer to this and simple tests let me think, that docker is killing the containers without any SIGNAL.

If this is really the case: How can I remove a node from the swarm gracefully without killing any containers that are currently running?

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.
