In server administration it is very important to understand how the running processes work in detail, from high load to slow response time processes, there comes a time when your server may start to become so slow or fail to respond sometimes, and as a consequence, it will require immediate attention, and here it comes the process management or Linux process management specifically in place.
When it is the time to kill a process or renice it and how to monitor the currently running processes and how these processes affect the system load. Let’s see how Linux process management will help us tuning the system
Our main points are:
Tuning performance with memory management
Managing memory with vmstat
Checking the system load with the top command
Monitoring disk I/O with iotop
Checking processes with the ps command
Checking performance with iostat and lsof
Calculating the system load
Discovering process IDs using pgrep and systemctl
Nice and renice processes
Sending the kill signal
I hope you like it.

Currently I have a 6TB harddrive with a single EXT4 partition used to store all my media files, while my root is on a 32GB flashdrive. I understand that reserved blocks are needed for defragmentation but even setting at 1% of the total disk space, it is 60GB reserved blocks. I wonder how much space is actually needed for EXT4 defragmentation and whether I can set reserved blocks to 1Gb or 500Mb for example?submitted by /u/akanosora

The storage team of ProfitBricks has been looking for a way to speed transfers between VMs on compute nodes and physical devices on storage servers, connected via InfiniBand, in their data centers. As a solution, they developed the IBNBD driver, which presents itself as a block device on the client side and transmits the block requests to the server side, according to Danil Kipnis, Software Developer at ProfitBricks GmbH.
“Any application requiring block IO transfer over InfiniBand network can benefit from the IBNBD driver,” says Kipnis.

Today’s software supply chain is fundamentally different than it was only a few years ago, and open source programs at large enterprises are helping to drive that trend. According to Sonatype’s 2016 State of the Software Supply Chain enterprises are both turning to existing open source projects to decrease the amount of code they have to write, and increasingly creating their own open source tools.
