Centos 6.3 NFS 'slower' than Ubuntu
location: ubuntuforums.com - date: February 7, 2013
I tried using centOS 6 instead of ubuntu for my nfs media server (Tired of the server stating that it wants to reboot due to automatic security updates every other day). I believe I had set it up the same with the same /etc/exports file and same drive being shared, but noticed that it was noticeably 'slower' than when it was a Ubuntu machine.
- Much slower to be mounted
- would 'time out'
- generally slower to access/brose the folders.
I am not referring to file transfers themselves.
I thought perhaps I was just being 'nutty' and just installed ubuntu back on the machine again and it is much smoother again (Very noticeable). Has anyone noticed this or have any ideas what is causing this? I am sharing a 3TB drive which has about 2.5TB of media on the folder being shared.
Cannot copy files > 2 GB to NFS mount on Ubuntu 12.04 server
location: linuxquestions.com - date: August 30, 2013
My "server" is really just an overgrown hard drive used for backup. It has 3 x 1 TB and 1 x 2 TB individual drives - no RAID. All are accessible via NFS, Samba and SSH.
The machine has run Ubuntu 8.04 and 10.04 just fine for many years. Recently I upgraded to Ubuntu 12.04 (yes I know I should reinstall rather than upgrade but I may be doing that or decommissioning in near future so I said what the heck). The upgrade seemed to work fine.
Today I noticed that I could not copy a file > 2 GTB to the sever via NFS. I get the message "Error writing file: File too large." I observed this in Gnome Commander and Nautilus on my CentOS 6 workstation. Here are some of the key configuration files.

Problems Connecting to a freeNAS server on SMB or NFS
location: ubuntuforums.com - date: March 1, 2008
Hey guys my system is a FreeNAS Server running several IDE Drives each of which is shared over SMB (for windows) and NFS (for *nix) This is where I have my 2 TB of Videos, Music, Photos, etc. stored all the drives are formated NTFS because I cam from a windows background.
My Mythbuntu Computer is a Athalon 64 with a smaller hdd (120 gig) and DVD drive. No tuner yet.
These are both hardwired to a router where they all have static IP addresses.
Now for my question.
How do I mount the Server from my Mythbuntu PC?
I'v followed guides all over the net and I generally recieve a
mount: wrong fs type, bad option, bad superblock on //server/share/folder,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

Unable to mount NFS Share [RPCPROGMNT: RPC: Timed out]
location: linuxquestions.com - date: August 3, 2008
Configuring NFS Sever has never been such a difficult task. But on FreeBSD I am still not being able to mount NFS share.
I have two FreeBSD Machines:
1.] NFS Server
2.] NFS Client
Settings of NFS Server:
# cat /etc/exports | grep -i exports
NFS: Ubuntu (server) and Mac OS X (clients)
- date: July 17, 2006
I'm a Mac user who was recently given a PC, which I plan to basically use as a headless server and [email protected]
client (as opposed to having the PowerMac continue to do double duty as both a desktop and a server). One of its server tasks I want it to perform is network storage for the two Macs' automated backups. Unfortunately, the Macs see that the PC has available NFS shares but won't let me mount them using the Finder's connect to server. I get an error message saying that the username and password was incorrect, even though it never asks me for a username or password.
PC server: Ubuntu Server 6.06 (kernel version 2.6.15-25-server), wired connection to the router
PowerMac G4: Mac OS X 10.3.9, wired connection to the router
PowerBook G4: Mac OS X 10.3.9, wireless connection to the router
I have full control of all of the computers involved.

NFS Large File Copies Fail Error writing to file: Input/output error
location: linuxquestions.com - date: June 27, 2009
I recently upgraded my file/media server to Fedora 11. After doing so, I can no longer copy large files to the server. The files begin to transfer, but typically after about 1gb of the file has transferred, the transfer stalls and ultimately fails with the message:
"Error writing to file: Input/output error"
I've run out of ideas as to what could cause this problem. I have tried the following:
1. Different NFS versions: NFS3 and NFS4
2. Tried copying the files to different physical drives on the server.
3. Tried copying the files from different physical drives on the client.
4. Tried different rsize and wsize block sizes when mounting the NFS share
5. Tried copying the files via a different protocol. SSH in this case. The file transfers are always successful when I use SSH.
Regardless of what I do, the result is the same. The file transfers always fail after approximately 1gb.
Some other notes.
1. Both the client and the server a

nfs mounted partition giving error "no space left"
location: linuxquestions.com - date: January 2, 2007
I have 2 linux system, with Redhat linux 9 as Operating system.
on one linux system (system A) i have created a nfs share
The /home partition is Storage device ( SAN). which 535GB.
of which 140 GB is used.
on another system (server B), i have mounted server A's home partition through nfs.
when users logon on on server B and access /home and create a file it tells "no space left" . tried with dd command and check
dd if=/dev/zero of=myfile count=50000 bs=1024
it gives error "no space left" . But when we do df -h
it shows only 140 gb used and 390 GB available but unable to creat any file.
on the server A console following error message appears
ext2_fs error (device sd(8,35)): ext2_new_block free blocks count corrupted for block group 50
suppose i logon as user directly on server A and give the command
dd if=/dev/zero of=myfile count=50000 bs=1024
The file myfile gets created.
[SOLVED] NFS mount Error: "System Error: Connection refused"
location: linuxquestions.com - date: October 16, 2010
Hi, Greetings !
I am trying to nfs mount a directory from my server on another workstation and it is throwing up the following error.
mount: mount to NFS server 'craycx1' failed: System Error: Connection refused.
I edited /etc/exports file on the server with correct syntax and there is nothing in /etc/hosts.allow and /etc/hosts.deny.
I am able to ssh from client to server and vice versa successfully.
rcpinfo indicates that NFS server is running..
Please suggest me whatelse can be wrong ?
Thanks in advance for your time and support.
