Mount.nfs: Mount(2): Input/output Error Mount.nfs: Mount System Call Failed
usually means that NFS server and client do not agree on the version nfs input output error linux of NFS offered, however this might not be the cause of your problems. So, could you login as root to the RHEL3 boxes
Rpc: Failed To Contact Portmap
and do an: rpcinfo -p server (server=resolvable name of your RHEL5). and provide the output? Also, what are the mount options you use on the /etc/fstab file (or automount config) on the RHEL3 side to mount the home dirs from RHEL5? Do the NFS imported mount windows nfs share on linux input output error partitions show up in df, does it hang, display the partitions as mounted but with no util info?...

I can ssh into the workstations but creating files gives the same Input/Output error. The server hard drives are fine BUT I do see this in /var/log/messages on every occurrence on the clients: kernel: svc: unknown version (3) I'm not able to log into the clients from the GUI so something serious is going on.

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 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 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: 3,015 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.
