A key performance metric to monitor on a Linux server is disk I/O (input/output) activity, which can significantly impact several aspects of a Linux server, particularly the speed of saving to or retrieving from disk, of files or data (especially on database servers). This has a ripple effect on the performance of applications and services.

The Debian Project Leader election results have been announced. Andreas Tille has been re-elected and will serve another term through April 2026. LWN looked at the election and candidates in early April.

Clear Linux is a minimal distribution primarily designed with performance and cloud use-cases in mind. The operating system upgrades as a whole rather than using individual packages. Extra software can be added to the system (along with associated dependencies) using pre-compiled bundles which can be accessed through the distribution's swupd software manager.

New compiler releases often bring with them new warnings; those warnings are usually welcome, since they help developers find problems before they turn into nasty bugs. Adapting to new warnings can also create disruption in the development process, though, especially when an important developer upgrades to a new compiler at an unfortunate time. This is just the scenario that played out with the 6.15-rc3 kernel release and the implementation of -Wunterminated-string-initialization in GCC 15.

Sometimes worms have a tendency to multiply once their can is opened. James Bottomley recently encountered that situation; he led a session in the filesystem track at the 2025 Linux Storage, Filesystem, Memory Management, and BPF Summit (LSFMM+BPF) to discuss filesystem behavior with respect to suspending and resuming the system. As he noted in his topic proposal, he came at the problem because he needed a way to resynchronize the contents of efivarfs after a system resume and thought there should be an API available to use. But, as the resulting thread shows, the filesystem freeze and thaw code had never been used by the system-wide suspend and resume code. Due to a scheduling mixup, though, several of us missed Bottomley's session, including Luis Chamberlain who has been working on hooking those two pieces up; what follows is largely from a second session that Chamberlain led, with some background information from the topic-proposal discussion and an email exchange with Bottomley.

Let’s start by defining a bad sector/bad block, it is a section on a disk drive or flash memory that can no longer be read from or written to, which usually happens due to permanent physical damage on the disk surface or failing flash memory transistors.

As more bad sectors build up, they can seriously impact your storage device’s performance, reduce its capacity, or even lead to complete hardware failure.

It is also important to note that the presence of bad blocks should alert you to start thinking of getting a new disk drive or simply mark the bad blocks as unusable.

Therefore, in this article, we will go through the necessary steps that can enable you to determine the presence or absence of bad sectors on your Linux disk drive or flash memory using certain disk scanning utilities.
