Alienware X58, Dell studio XPS and OpenSolaris

Previously I had blogged about pogolinux (an i730 system).  Since then we got a couple more boxes to try.  

Alienware X58: What a hunk of system and I don't mean that in a good sense.  It's back breaking.  The first set of systems we got were DOA.  As two of us were lifting one from the box an uncomfortable loud "thunk"  came from box.  When I opened it, the fan had come loose from the side and was flopping all around.  We sent those back and got new ones.  These were definitely better. They came out of BIOS.   Installing OpenSolaris via USB was quick.  About 5 minutes and this image had all the languages.

I must add that the pogolinux box without was just a wee bit quicker.

Recovering an OpenSolaris system

Before I decided to blog this, I figured I would first search to check out if there are other blogs that discuss the techniques required to recover a system.  Turns out sriram blog talks about using beadm technique but here a bit more elaborate version.

Our local admin was trying to upgrade the AI server to a newer build.  The system was installed with OpenSolaris 2009.06 and he had published a number of install services.  However a simple pkg image-update failed miserably and so did pkg install SUNWipkg.  A quick investigation revealed that someone had added an older version 2008.11 version of the SUNWipkg(pkg verify is your friend). This normally would be possible,  but the user had added the SVR4 version of SUNWipkg.  So the system was not upgradable.  A reinstall was not the answer he wanted to hear.

So here's what we did:

1. Created a new beadm from the snapshot and activated it.

2. Rebooted to the new BE and mounted the old one.

3. pkg image updated the old BE.

4. Upon successful completion, activated the old BE and rebooted it.

These are the steps. All these commands were run as root.  The name of the BE was opensolaris.

1. beadm create -e opensolaris@install opensolaris-1

2. beadm activate opensolaris-1; reboot

3. (after logging in), beadm mount opensolaris /mnt

4. pkg -R /mnt SUNWipkg

5. pkg -R /mnt image-update

6. reboot.

Why I removed Ubuntu ..Really!!

 

A couple of  months ago, I got  a new workstation.  A quad core Xeon box from Dell. It came with preinstalled Ubuntu.  I decide to play with that for while.  After a while I noticed that the system would randomly reset. Ah the darn unstable linux is what I thought!!

I reinstalled the system with OpenSolaris 2008.11 and it ran for a day or so. The system reset again.  Annoyed I started looking at /var/adm/messages and I found that there was a hardware fault detected by FMA and taken appropriate action.  Now it was nice to call Dell Support  and tell them definatively the cause, diagnosis and that I needed a new motherboard.  

The rep asked me what test was running.  I said nothing. This functionality is built into OpenSolaris...and it's free!!  One cannot get this running linux.

Here's what fmadm faulty printed

pogolinux offers preinstalled OpenSolaris 2008.11 systems

 

We recently got a few Nehalem systems from pogolinux.  When ordering we noticed that they offered to preinstall the systems with OpenSolaris 2008.11.  Naturally we chose it.

The systems arrived, we plugged them in and there was the login screen for OpenSolaris.

Nice!!

Using Distro constructor to add SVR4 pkgs to your image

As a developer, I often have to build modified images to test out my changes.  Using DC one can do this very easily. I imagine others might have similar  needs, hence here is a quick tutorial.

The distro_constructor lists the set of steps required to build an ISO. One can see this by running:

distro_const build -l <config_file.xml>. Here's an output from one of my runs.

distro_const build -l slim_cd.xml
Step           Resumable Description
-------------- --------- -------------
im-pop             X     Populate the image with packages
im-mod             X     Image area modifications
slim-im-mod        X     Slim CD Image area Modifications
br-init            X     Boot root initialization
slim-br-config     X     Slim CD boot root configuration
br-config          X     Boot root configuration
br-arch            X     Boot root archiving
slim-post-mod      X     Slim CD post bootroot image area modification
grub-setup         X     Grub menu setup
post-mod           X     Post bootroot image area modification
iso                X     ISO image creation
usb                X     USB image creation

Modifying an image in DC is achieved by addding an extra step. In the example below, I had to test the install changes to support booting off a multi-terabyte disk. My SUNWinstall, an SVR4 pkg, had the updated changes. Since the installer is part of the microroot, I decided that changes had to be applied after "Image area modification".

In the slim_cd.xml file these steps are called out in the finalizer class. Each step is a script sub-class which has a step name, a message and the script to call. Invoking my favorite editor (emacs!!) I searched for "<finalizer>". The following lines were added to create a new step.

 <script name="/export/bld_images/mtb-pkgadd">
         <checkpoint name="mtb-pkgs" message="Add MultiTB pkgs"/>
 </script>

These lines were inserted after the "im-mod" step. Next, I created my script mtb-pkg. When the script is called from the distro constructor, stdin and stdout are not available. For a pkgadd to run in this mode, a private version of the admin file is required. My mtb-pkgadd script was:

 #!/usr/bin/ksh93

ADMIN_FILE=/tmp/admin.$$
cat << \\ADMIN_EOF > $ADMIN_FILE
mail=
instance=unique
partial=nocheck
runlevel=nocheck
idepend=nocheck
rdepend=nocheck
space=nocheck
setuid=nocheck
conflict=nocheck
action=nocheck
networktimeout=60
networkretries=3
authentication=quit
keystore=/var/sadm/security
proxy=
basedir=default
ADMIN_EOF

pkgadd  -a ${ADMIN_FILE}  -d /brmnas/nadkarni/slim_wses/gui-changes/packages/i386/nightly-nd -R /export/bld_images/mtb/build_data/pkg_image SUNWinstall

That is really all that is need to apply the changes. Since I wanted to verify that the pkg was applied correctly, I decided to stop after mtb-pkgs step.

distro_const build -p slim-im-mod mtb.xml

DC stops at the start of the step. Running

distro_const build -l mtb.xml
 
Step           Resumable Description
-------------- --------- -------------
im-pop             X     Populate the image with packages
im-mod             X     Image area modifications
mtb-pkgs           X     Add MultiTB pkgs
slim-im-mod              Slim CD Image area Modifications
br-init                  Boot root initialization
slim-br-config           Slim CD boot root configuration
br-config                Boot root configuration
br-arch                  Boot root archiving
slim-post-mod            Slim CD post bootroot image area modification
grub-setup               Grub menu setup
post-mod                 Post bootroot image area modification
iso                      ISO image creation
usb                      USB image creation

I verified the bits and then resumed the build process by running:

distro_const build -R mtb.xml

 

 
  
 
  

2008.11 in the side view mirror

Call me the "late Latif".  Most people blog about a release when it's released.  I blog about it when it's aged a bit.   After months of hard work it was great to finally deliver 2008.11.  A functionality that has not been discussed in the blogs thus far is  the support for booting off a multi-terabyte disk.   While support for multi-terabyte non boot disk has been available for quite a while, boot disks were limited to under 1TB. Boot disks can now be upto 2TB. This feature along with the prototype version of the Automated Installer should interest users in the enterprise space who have been waiting for jumpstart type functionality from the Caiman project for a while.

Another component delivered by the Caiman project is the Distro Constructor(DC).  This tool enables one to create liveCD or Automated Install (AI) images.  It is preferable to run this tool on a reasonbly powerful machine as it does
require a fair bit of compute power.

 When I first tried to build it on my Toshiba M9, I noticed that I could keep my coffee warm by the heat it was generating. My desktop, a W2100z was no better. Building images on this
system upped the decibel level of fan noise to that of a jet engine.  Luckily, I was able to snag an Ultra 24.  Its quiet and efficient. I can build images in 20-30 minutes on this puppy.
Often its even faster since I use DC's snapshoting capability

I view building ISOs as BDC (Before DC) and ADC (After DC). In the BDC world, one used "cdkit". It required a complex setup and assummed a very specific environment. Even users inside Sun would have to struggle to create an ISO.  Distro Constructor was designed to eradicate the "fear" of trying to build an ISO and I feel this goal has been met.

So go ahead fire up those fans, use  DC and send us your feedback either on caiman-discuss@opensolaris.org
or by filing bugs for new features.

sparc port..

Over the last couple of months I have been mentoring Chris Walsh and monitoring the sparc port.  It  was a lot of fun.  Chris's dogged persistence on getting this to work is remarkable.  He has blogged his trials and tribulations at
http://blogs.sun.com/cwalsh/entry/porting_opensolaris_project_indiana_to  and http://blogs.sun.com/cwalsh/entry/porting_opensolaris_project_indiana_to1

Chris will be giving a talk on this at the FROSUG meeting in August where you can see a demo.

Bunnahabhain and SVM


A while back we finally started a project to enable friendly names for SVM volumes.  As users of SVM know, the volume names until now could only be dxxx and the names for hotspares had to be hspxxx.  We needed to fix that.  So as  is typical for our group the project that delivered it was called  bunnahabhain (prounced as bunahavan).  Yes another single malt scotch.

This project was putback in Nevada build 37.  For more info look here.

Frkit available

I am really excited to announce that frkit is now available on the opensolaris laptop community. We are still fighting the legalities of getting things out.   But that is improving significantly.  Over the next few months, expect to see many more modules, including the NDIS wrapper.
