sijicha Posted May 18, 2023 Share Posted May 18, 2023 Hello everyone I have a question about hard disk reading. When I try to modify the /sys/bus/pci/devices/0000:xx:00.x/sriov_numvfs file, the system prompts me "bash: echo: write error: Input/output error " After searching, I found that this is suspected to be a bad sector problem. I used the xfs_repair command to repair all my hard disks in the array, and then put my system U disk into the windows system for detection, and there were no bad sectors. I would like to know which hard disk the folder is deployed in so that I can perform deeper detection. I will upload the results of my scan with xfs_repair -nv /dev/mdx command later for reference. thank you all! Quote Link to comment
Solution sijicha Posted June 5, 2023 Author Solution Share Posted June 5, 2023 In fact, this is not a hard disk read problem. But my network card is a counterfeit version and does not support sriov. After I replaced a network card, the file was successfully modified. An infuriating yet frustrating coincidence.... Quote Link to comment
