[Solved] Log Error: kernel: blk_update_request: I/O error, dev fd0, sector 0

Environment: Center OS 7.6 virtual machine

Log error: kernel: BLK_ update_ request: I/O error, dev fd0, sector 0

Query the error information and find that there may be no floppy disk, and the floppy disk drive is loaded when the system is started.

Verification: lsmod | grep float

Step 1: (Not Work)

Try creating nofloppy.conf in the /etc/modprobe.d/ directory to disable the floppy module from loading on boot

vim /etc/modprobe.d/blacklist.conf

#Add command line
blacklist floppy


echo "blacklist floppy" | tee /etc/modprobe.d/blacklist-floppy.conf


Step 2: The use of blacklist does not disable the way, and finally choose to add the following code in grub to boot disable

vim /boot/grub2/grub.cfg
#Add code
#Disable floppy drive

After rebooting and checking the logs, no errors were reported.
