How To Force fsck (Filesystem Consistency Check) After Reboot

With old sysvinit and Upstart, users could force a disk check on next reboot using a simple command (sudo touch /forcefsck), but that’s no longer the case nowadays, with most Linux distributions using systemd. This article explains how to force fsck to run at boot time in two ways, which work with systemd. You’ll also find a command that shows when a partition was last checked by fsck, at the end of the article.

Building a Raspberry PI Cluster – Part IV: Monitoring

Having a cluster built out of Raspberry Pi’s is not only fun but also eases your work. As we discussed in our latest article in the series you can use the cluster to compile software or make it gather data from various sources on the Internet. There are many uses for such a thing. However, after compiling for an hour straight you might get curious as of how your nodes perform. How they work under load, if they’re not under-powered or if the CPU temperature is not rising above desired levels.

Dual booting Windows and Linux using UEFI

Rather than doing a step-by-step how-to guide to configuring your system to dual boot, I’ll highlight the important points. As an example, I will refer to my new laptop that I purchased a few months ago. I first installed Ubuntu Linux onto the entire hard drive, which destroyed the pre-installed Windows 10 installation.read more

[$] New system calls for memory management

Several new system calls have been proposed for addition to the kernel in a
near-future
release. A few of those, in particular, focus on memory-management
tasks. Read on for a look at process_vm_mmap() (for zero-copy
data transfer between processes), and two new APIs for advising the kernel
about memory use in a different process.
