Ls Reading Directory . Input/output Error Ubuntu
answer The best answers are voted up and rise to the top Interpreting dd Input/Output error up vote 4 down vote favorite I tried to copy /dev/Storage/Storage (an LV under LVM) to an image file using a dd | pv | dd pipeline. dd reported an error, and I want to know whether dd finished copying my disk or stopped due to the error. I'm not sure since it gave input/output error centos me two different outputs: one with an error at the top and one without. I'd take a guess and say it didn't because between the two there's only an extra 0.1 seconds and no extra data, but I'm not sure if it did or not. /dev/Storage/Storage is a 1 TB disk (terabyte = 1012 = 10004) or 931.51 GiB (gibibyte = 230 = 10243) or 1953513472 sectors. The filesystem on the disk is messed up and doesn't work properly. $ sudo dd if=/dev/Storage/Storage | pv | dd of=Storage.img dd: error reading ‘/dev/Storage/Storage’: Input/output error ] 1627672400+0 records ins] [ <=> ] 1627672400+0 records out 833368268800 bytes (833 GB) copied, 75181 s, 11.1 MB/s 776GB 20:53:01 [10.6MB/s] [ <=> ] 1627672400+0 records in 1627672400+0 records out 833368268800 bytes (833 GB) copied, 75181.1 s, 11.1 MB/s linux dd share|improve this question edited Apr 27 at 15:26 Anthon 47.7k1462126 asked Aug 16 '15 at 0:08 Scoopta 314214 (1) Please show the command(s) that you typed to get this output. (2) Do you know how big you disk is? Please do not respond in comments; edit your question to provide the requested information. –Scott Aug 16 '15 at 0:36 One obvious question is whether your disk has 1627672400 sectors

And I used to copy vdi files as a kind of backup. Previously I did this (copying vdi file and then copying it back) many times without any problem. But today I experienced this error VirtualBox VMs/win_7$ cp ../../Bkps/win_7.vdi . cp: error reading ‘../../Bkps/win_7.vdi’: Input/output error cp: failed to extend ‘./win_7.vdi’: Input/output error I googled for this a little but from the advices on similar problems I undersood nothing unfortunately. Could anyone suggest how to solve this, please? The output from the dmesg is, (and I understand nothing from it) [ 2347.982876] ata1.00: exception Emask 0x0 SAct 0x1900406f SErr 0x0 action 0x0 [ 2347.982887] ata1.00: irq_stat 0x40000008 [ 2347.982895] ata1.00: failed command: READ FPDMA QUEUED [ 2347.982908] ata1.00: cmd 60/08:70:d0:da:f4/00:00:2e:00:00/40 tag 14 ncq 4096 in [ 2347.982908] res 41/40:08:d0:da:f4/00:00:2e:00:00/00 Emask 0x409 (media error)

On standby: auto umount NFS-share via system-sleep-hook with systemd.This works flawlessly some hours or even days. But after some time, the 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 output error on server!), but the correct freesize of the 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 input output error the clients which worked before, too.Any idea what's going wrong?additional info:server: /etc/exports _______________________ /srv/nfs/myshare 192.168.2.0/24(rw,all_squash,anonuid=33,anongid=33,no_subtree_check)(yes, the mapping is needed and right.)clients:/etc/fstab _______________________ servername:/srv/nfs/myshare /home/carl/nfs nfs4 noauto,soft,user,_netdev,timeo=14,rsize=8192,wsize=8192 0 0/usr/lib/systemd/system-sleep/umount-nfs _______________________ #!/bin/sh case $1 in pre) umount -f /home/carl/nfs ;; esac Last edited by Carl Karl (2014-09-21 17:07:47) Offline #2 2014-09-16 14:15:27 nomorewindows Member Registered: 2010-04-03 Posts: 3,017 Re: [solved] NFS: "ls: reading directory .: Input/output error" after time Somehow your nfs mounts have gone stale. 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.

I would copy/clone the the whole partition (using eg. dd) just to make data safe (don't forget to unmount the partition first). Then you can experiment with one of the copies to recover the files and fix filesystem; try to run fsck, or this might help as well: http://www.cgsecurity.org/ (photorec, testdisk) htt
