On 11 Dec 2023 15:46 +0100, from rachid.oub...@elum-energy.com (Rachid Oubelk): > Dear support team,
A clarification; this mailing list is not a "support team". It's a group of people, many of which who share little more than the fact that they use Debian to varying degree, and with varying levels of experience and expertise. You should treat any response you get from this list accordingly, and know that nobody here is under any obligation. If you are running mission-critical applications on Debian, you may want to investigate paid support through some company which provides that service. _That said,_ > Please, we are using Debian GNU/Linux 9.13 (stretch) installed on a > UC-8112-LX controller version 3.4, I am not familiar with the UC-8112-LX controller.

Very urgent. _Usually_ an I/O error is caused by a storage-level problem such as a sector read error from which the storage device could not recover by using the error-correcting data stored on it. You should see more detailed information in the kernel logs; check /var/log/syslog (exact locations can vary depending on your syslogd configuration) and the output of dmesg (may have been rotated out, especially if the system has been rebooted) for a period around the time of the error. -- Michael Kjörling 🔗 https://michael.kjorling.se “Remember when, on the Internet, nobody cared that you were a dog?”
