do I fix this problem?A. This message appears when you don’t have a floppy drive attached to Linux server. Solution is quite simple just disable driver for floppy and reboot the system. You can verify this with the following command (this solution works with RHEL, CentOS, Redhat, Ubuntu/Debian and other Linux distros) : # lsmod | grep -i floppy Output:floppy 95465 0Open file called /etc/modprobe.d/blacklist: # vi /etc/modprobe.d/blacklist Listing a module (driver name) in this file end_request i o error dev fd0 sector 0 suse prevents the hotplug scripts from loading it. Usually that'd be so that some other driver will bind it instead, no matter which driver happens to get probed first. Sometimes user mode tools can also control driver binding. Append following line: blacklist floppy Save and close the file. Now reboot the Linux server: # reboot Share this tutorial on:TwitterFacebookGoogle+Download PDF version Found an error/typo on this page?About the author: Vivek Gite is a seasoned sysadmin and a trainer for the Linux/Unix & shell scripting.

I have removed the floppy drive from the VM configuration (as my host machine does not have one, and I haven't used one in literally 12 years). When the VM boots, an http://unix.stackexchange.com/questions/147370/how-does-one-disable-the-floppy-module-from-loading-on-boot-in-centos7 error message comes up: end_request I/O error dev fd0 sector 0 The error does not halt the machine from running, but i would like to deal with the issue. After looking around online, it seems that the floppy module is loaded at start up by default, whether there is a floppy drive connected or not. This can be disabled by telling the system not to load the module at start up, and apparently the different flavours of GNU Linux all have different ways of doing this. I've tried several methods, and all have failed as the module still loads on start up and the same error message still appears during boot. I've tried adding the following line to each corresponding file: /etc/modprobe.conf: alias floppy off /etc/modprobe.d/blacklist.conf: blacklist floppy /etc/modprobe.d/floppy.conf: blacklist floppy In each case those files did not exist as default and needed to be created, and thus far every method has failed. Does anyone have a definitive answer for how to disable the floppy module from loading on boot in CentOS 7 specifically? I have asked on the CentOS 7 forums, but there has not been any reply, hence me asking here instead. Please note that the solution for CentOS 6.5 does not work. floppy centos share|improve this ques

How to set kernel boot options Kernel boot options are contained in the file /boot/grub/grub.conf. Each installed kernel has a group of lines called a stanza describing: the title of the operative system to load where to find the boot partition (in grub named root!) what kernel (vmlinuz-*) to boot, with additional kernel options the name of the initrd to load A typical stanza looks something like this: title Fedora 13 (2.6.33.5-124.fc13.i686.PAE) root (hd1,7) kernel /vmlinuz-2.6.33.5-124.fc13.i686.PAE ro root=/dev/mapper/VG_f13-LV_f13_root rd_LVM_LV=VG_f13/LV_f13_root rd_NO_LUKS rd_NO_MD rd_NO_DM LANG=en_US.UTF-8 SYSFONT=latarcyrheb-sun16 KEYTABLE=us rhgb quiet initrd /initramfs-2.6.33.5-124.fc13.i686.PAE.img title CentOS 5 (2.6.18-194.3.1.el5) root (hd0,4) kernel /vmlinuz-2.6.18-194.3.1.el5 ro root=/dev/mapper/VG_CentOS-LV_CentOS_root rd_LVM_LV=VG_CentOS/LV_CentOS_root
