(version6.5.11)Hard disk read and write problems

Go to solution Solved by sijicha,

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!
