Bash Input Output Error
can answer The best answers are voted up and rise to the top ntfs-3g: Input/output error up vote 6 down vote favorite 4 For the past 3 days (after an update) my Debian Jessie refuses to mount NTFS disks. I reinstalled libfuse2 and ntfs-3g, yet I get the same Input/output error I tried the same disks under Windows 7 and OSX Mavericks (using ntfs-3g) and they work fine. I purged linux bus error ntfs-3g and reinstalled, and still the same problem. The disks will sometimes mount and sometimes won't mount. If they do mount, I am sometimes able to go into the mount directory, whereas some other times, I get a bash error Input/output error for the mount directory. The times I am able to go into the mount directory, when I try an ls -l, I see tons of question marks, instead of file/dir attributes. I have tried ntfsfix and chkdisk under windows, and they both reported no problems, it is only under this Jessie install that all of a sudden I can't mount them properly. dmesg has no usefull info other than the external disk being attached: [12816.210969] scsi 20:0:0:0: Direct-Access Seagate External SG16 PQ: 0 ANSI: 4 [12816.211825] sd 20:0:0:0: Attached scsi generic sg7 type 0 [12816.212542] sd 20:0:0:0: [sdg] 732566642 4096-byte logical blocks: (3.00 TB/2.72 TiB) [12816.213591] sd 20:0:0:0: [sdg] Write Protect is off [12816.213595] sd 20:0:0:0: [sdg] Mode Sense: bf 00 00 00 [12816.214782] sd 20:0:0:0: [sdg] Write cache: disabled, read cache: enabled, doesn't support DPO or FUA [12816.215561] sd 20:0:0:0: [sdg] 732566642 4096-byte logical blocks: (3.00 TB/2.72 TiB) [12816.242055] sdg: sdg1 sdg2 [12816.243244] sd 20:0:0:0: [sdg] 732566642 4096-byte logical blocks: (3.00 TB/2.72 T

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.

Updated June 19, 2016 Every process in Linux is provided with three open files( usually called file descriptor). These files are the http://www.linuxtechi.com/standard-input-output-error-in-linux/ standard input, output and error files. By default : Standard Input http://linoxide.com/how-tos/inputoutput-error-bad-blocks-how-to-restart-linux/ is the keyboard, abstracted as a file to make it easier to write shell scripts. Standard Output is the shell window or the terminal from which the script runs, abstracted as a file to again make writing scripts & program easier Standard error is the same as input output standard output:the shell window or terminal from which the script runs. A file descriptor is simply a number that refers to an open file. By default , file descriptor 0 (zero) refers to the standard input & often abbreviated as stdin. File descriptor 1 refers to standard output (stdout) and file descriptor 2 refers to standard error (stderr). These input output error numbers are important when you need to access a particular file , especially when you want to redirect these files to the other locations, File descriptors numbers go up from zero. Redirecting Standard Output Syntax to redirect the output of a command to a file. # Command_options_and_arguments > output_file Example : linuxtechi@localhost:~$ cat /proc/cpuinfo > command.txt We can see the data that would have gone to the screen with more command : linuxtechi@localhost:~$ more command.txt processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 37 model name : Intel(R) Core(TM) i3 CPU M 370 @ 2.40GHz stepping : 5 microcode : 0x616 cpu MHz : 0.000 cache size : 6144 KB physical id : 0 siblings : 2 core id : 0 cpu cores : 2 apicid : 0 initial apicid : 0 fpu : yes fpu_exception : yes cpuid level : 5 wp : yes The > operator tells
LINUX HOWTO | 2 Replies More Bad Disk This article I am trying to explain how to deal with " Input/output error " when you initiate any commands in Linux. I have pointed some examples that reports similar error. # 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 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 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 :-). 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 . Forced Reboot echo 1 > /proc/sys/kernel/sysrq echo b > /proc/sysrq-trigger Forced Shutdown echo 1 > /proc/sys/kernel/sysrq echo o > /proc/sysrq-trigger You might also likeHow To Fix / Repair Bad Blocks In LinuxHow To Backup LVM Configuration On Linux (vgcfgbackup & vgcfgrestore)
