I had an issue a couple of days ago in which I had the /docker filesystem full and unable to pinpoint exactly which docker container is using it.
Fortunately docker comes with powerful utilities to help you out with this.
Follow what comes if curious.
How to check how docker is using the system space:
The following commands even if they are close they provide different output. the -v option will give you way more details docker system df -v docker system df
You have installed vmware tools provided by your ESXi host but you see this message on some servers: "VMware Tools is installed and supported, but a newer version is available on the host."
If you carefully read VMware documentation you will find out they recommend using open-vm-tools instead of VMware tools, as mentioned in the article (link at the end).
Improved stability, automatic updates, smaller footprint, package optimised for each distribution are some of the reason behind this recommendation.
I attached a disk one day and was impossible to create datastore on it via web interface.
Well, did not thought much about it and went directly on command line, via ssh and if you are curious, please follow.
I got bored and thought if I can mix up an old PC with a newer(ish) graphics adapter so I took my old 2009 server from the storage and added on it GTX 1050 Ti.
The results were spectacular and I am sharing with you this experience.
You are here because you cannot find glances via apt, right?
I got into the same issue but differently. I removed glances because it was giving the following error: glances AttributeError: 'ThreadScanner' object has no attribute 'isAlive'.
And when I attempted to reinstall it back, SURPRISE! Not available :D
Actually you cannot resize the OS partition on an existing ESXi installation but you can backup the configuration, reinstall with the right options and restore back the configuration.
You could probably also migrate during the installation process but I haven't tested that yet.
With SSD arriving more and more in our lives it is natural to find it on linux servers too.
Not working with SSD in this area much, haven't found much interest of finding ssd related things in Linux so far.
So, nowadays one can wonder wondering: how would I know if my disks in Linux are SSD or not?
A valid response would be: close the system, open it up and see what disk you have there :)))
But what if this is a linux server far far away? You need to be able to find out these things from OS level.
