On standby: auto input output error linux rm umount NFS-share via system-sleep-hook with systemd.This works flawlessly some hours or even days. But after some time, the input output error linux usb following happens:1. mount nfs-share: no error message2a. trying to access that folder via filemanager, e.g. thunar: folder seems to be empty (it isn't on server!), but the correct freesize of the bash input output error NFS-share on server is displayed in the statusbar.2b. trying to access that folder via commandline: $ ls ls: reading directory .: Input/output errorThe very same worked just a few hours before, I haven't changed anything meanwhile. Apart from standby (--> auto umount NFS-share) and resume (manual mount NFS-share) on the clients which worked before, too.Any idea what's going wrong?additional info:server: /etc/exports

You'd need to remount them or restart nfs related services. Dmesg or syslog output may help. I may have to CONSOLE you about your usage of ridiculously easy graphical interfaces...Look ma, no mouse.

File Input Output Error Linuxany commands in Linux. I have pointed some examples that reports similar error. linux input subsystem # du -bash: /usr/bin/du: Input/output error #mkdir sampledir mkdir: cannot create directory `sampledir': Input/output error Input/output error while running the command linux input output error deleting file mostly due to two reason. Either it could be bad blocks on the disk or someone hacked your machine. In this situation first suggestion would be to check /var/log/messages for any disk related alerts (might https://bbs.archlinux.org/viewtopic.php?id=187131 see some sense key alerts). tail -n 100 /var/log/messages tail -f /var/log/messages If you notice any disk issues , try any disk utility to confirm this. One option would be use smarttools. You can check smartool option to fix bad blocks. If you already installed it you can take the advantage of that. Next immediate action would be take backup of your system. Good if you already have it :-). http://linoxide.com/how-tos/inputoutput-error-bad-blocks-how-to-restart-linux/ If you have good backup its safe to reboot.If your system was hacked there are chances they might messed up your file and system would not work after reboot. You can also try fsck but it really dont fix most time if it bad block issue. Fsck can fix only if it related to any filesystem related issues. Usually fsck will fail in between as when it try to read the file at bad block. Now if try to reboot , it can also give the same output. You can try init 6. # reboot bash: /sbin/reboot: Input/output error # shutdown -r now bash: /sbin/shutdown: Input/output error If the above reboot commands doesnot work try either forced reboot or shutdown .

Everything has been going fine and I have not made any changes for a while. However, I have just noticed that Webalizer is no longer producing reports properly (they seem garbled) and now I cannot even copy files via FTP or even do a mkdir without getting an error (see below). Code: mkdir testing mkdir: cannot create directory `testing': Input/output error I tried to search for this and found people had similar errors but they mostly seemed to be tampering with their partitions and I have not been doing this.
