Newbie Joined: May 9, 2014 Messages: 15 Thanks Received: 0 Trophy Points: 4 Hello, I'm quite new to Freenas and BSD. With my installation I ran into the following problem. I'm using freenas nfs shares as a backup space for some servers. All my script does is mount the freenas nfs share and than use rsync to copy a few folders on a regular basis. Freenas/ZFS than does snapshots on the shares. So far so good, but what I experience is, that I get a lot of these messages: Code:rsync: readdir("/mybackup/files/files.txt"): Input/output error (5) and in dmesg: Code:nfs: server freenas.intern.lan not responding, timed out cat /proc/mounts shows the following mount options Code: nfs rw,relatime,vers=3,rsize=16384,wsize=16384,namlen=255,soft,proto=udp,timeo=60,retrans=20,sec=sys,mountaddr=172.16.4.25,mountvers=3,mountport=726,mountproto=udp,local_lock=none,addr=172.16.4.25 Any ideas on what might be the problem? I'm happy to provide more information on the setup if needed.
