Re: SS4200-E no_root_squash

idata · ‎01-24-2010

I have made a recent purchase of the SS4200-E with the sole purpose of running as a NFS server. I edit the /etc/exports file to reflect the no_root_squash needed to meet my needs and it appears that the system resets this setting each time it restarts. There has got to be a fix for this issue but I can seem to find any solution yet.

Any Advice?

Thanks in advance.

The system reverts to the original /etc/exports (and possibly other files) every reboot. I don't know where you could hide something to do that.

Below steps worked for me..

Step 1: edit /etc/exports

· / *(rw,sync,no_root_squash)

· Step 2: execute /etc/init.d/portmap restart

· Step 3: execute /etc/init.d/nfs restart

· Step 4: execute /etc/init.d/iptables stop

· Step 5: verify by executing "showmount –e localhost"

step 6: Ensure that gateway ip (netstart -nr)

Cool! And that persists beyond reboots?

KAMALANATH_N_Intel · ‎01-28-2010

yes..

I just ensured with the linux team, below steps will permanantely make changes..

Step 1: edit /etc/exports

· / *(rw,sync,no_root_squash)

· Step 2: execute /etc/init.d/portmap restart

· Step 3: execute /etc/init.d/nfs restart

· Step 4: execute /etc/init.d/iptables stop

Step 5 : · Step 6: verify by executing "showmount –e localhost"

step 6: Ensure that gateway ip (netstart -nr)

Step 1: edit /etc/exports

· / *(rw,sync,no_root_squash)

· Step 2: execute /etc/init.d/portmap restart

· Step 3: execute /etc/init.d/nfs restart

· Step 4: execute /etc/init.d/iptables stop

Step 5 : chkconfig nfs on

Chkconfig portmap on

Chkconfig iptables off

· Step 6: verify by executing "showmount –e localhost"

step 6: Ensure that gateway ip (netstart -nr)

I was hoping you could elaborate on this a little more. When I run step 2 below I get the following messge

-sh: /etc/init.d/portmap: not found

Further I don't see the other files that you mention under the init.d directory. It appears that portmap, nfs and iptables run from somewhere else.

Any ideas on this?

Thanks

Hello sean,

Which OS are you using?

make sure you have the following package installed in your OS.

1. portmap

2. NFS-utils

3.iptables

Issue the below commands to know whether you have NFS packages installed in your build.

# rpm -qa |grep portmap

# rpm -qa|grep iptables

# rpm -qa|grep nfs

I have RHEL 2.6 kernel machine and below lines will configure NFS setup permanently.

Step 1: edit /etc/exports

· / *(rw,sync,no_root_squash)

· Step 2: execute /etc/init.d/portmap restart

· Step 3: execute /etc/init.d/nfs restart

· Step 4: execute /etc/init.d/iptables stop

Step 5 : chkconfig nfs on

Chkconfig portmap on

Chkconfig iptables off

· Step 6: verify by executing "showmount –e localhost"

step 7: Ensure that gateway ip (netstart -nr)

Thanks,

kamal.

Linux version 2.6.19.2 (soho@lsoho059.lss.emc.com) (gcc version 4.2.1) # 1 PREEMPT Tue Jun 24 04:35:38 MDT 2008

This is the version of Linux that shipped on the unit. I came installed with a 256MB DOM and boots from that. I'm guessing that you were not responding to that OS when you posted your solution.

Thanks

I'm very interested in the solution for 1.1.11.32736. The file /mnt/soho_storage/config/exports apparently regenerates on reboot.

I wonder if it's possible to edit the script that regenerates this file. Anyone know where it is?

I have exactly the same no_root_squash need as the op and have tried following the instructions in response 2 and 4 but my /etc/init.d doesn't contain the executables listed. Here is the contents of my /etc/init.d:

S20urandom S40bond-init S41netplug S50sshd S60executord default_ip.awk rcS

S39interfaces S40network S50samba S59hostnamed cups hotplug zeroconf

I believe I'm running the latest firmware, 1.1.11.32736, and nfsd is enabled and working (i.e. I can mount SS4200-e volumes from my linux boxes using nfs).

idata · ‎02-10-2010

Since there's no "/etc/init.d/nfs restart" script with my firmware, I can instead just type "exportfs -a" after adding no_root_squash to exports. This gets makes it work until the next reboot.

KAMALANATH_N_Intel · ‎02-11-2010

oh really!..

Does it work for you?

Anyways, thanks for sharing the info!

idata · ‎02-11-2010

Well, it's only a temporary workaround. I'm still looking for a way to do this automatically so that it works after a configuration change or reboot.

That works! Thanks for posting the answer. Please let us know if you run across a more permanent solution.

For ultimate configurability and control, you could use the hardware only SKU which is just the SS4200-E without the EMC DOM, and install Linux. Or just remove the DOM. Obviously this isn't a supported configuration from Intel, but you would have more options for greater capabilities.

The SS4200 is just a 945GZ GMCH motherboard with a ICH7R south bridge (chipset software RAID). The eSATA port is controlled by a SIL3132 eSATA controller. The NIC is an Intel® 82573E 10/100/1000 Megabits per second (Mb/s) Ethernet Local Area Network (LAN) Controller. There should be no problem getting generic Linux drivers for those components.

The issue may be installing with some sort of video capabilities. The http://www.intel.com/support/motherboards/server/ss4200ehw/sb/CS-028981.htm Windows Home Server* Integration Guide shows how to use a video controller on the system with the use of a PCIe x1 to PCIe x16 flex extender.

You could probably even get a different DOM and use that for the OS. The SS4200-E system ships with a 256MB DOM for the EMC OS, but the system itself should support a larger DOM size. The DOM is just plugged into an IDE port.

Then all you need is a USB keyboard, mouse and CD-ROM.

You will find a permanent solution if you google ss4200 "enable no_root_squash".
