OpenSolaris Bible: First Impressions

I got home from work last night and had my new OpenSolaris Bible [Amazon $32] sitting at my doorstep.  Browsing through it, I was fairly impressed with the range of tidbits they covered. ZFS, iPKG, SMF, FMD, xVM, Zones, Java and C++ development, etc.

First thing I decided to play with was getting those remote CIFS shares mounted (they had been accessible via file explorer, but not via command-line).  Unfortunately, it required I reboot the machine after enabling the smb/server... and well, for some unknown reason that currently takes 4 hours... so I didn't get to play with it much.  I did however manage to get one of the shares to mount... Still trying to get the automount to work, but it's a start.

Taking the book to work today, I decided to play with FMD... Here's some comparison results between the work machine and the home machine... [Note: 'eris' is the work machine. 'serveris' is the home machine]

Now, what else can I play with?

Hanging at Hostname: serveris

I had to reboot last night, so I made sure to keep track of the time.
10:58pm I had told Grub which instance to run and it was waiting at Hostname: serveris
1:30am I went to bed and it was still sitting there
7:30 this morning I check 'dmesg' and it shows nothing at all until 2:55am

So it took 4 hours to boot. That's pretty lame.

Project Darkstar

I recently had this conversation with Owen (rest of the conversation is here):

Hi Malachi,

I haven't forgotten about you. Good news though. We have recently gotten approval to make the server api as well as the interfaces for writing custom services, authenticators, etc GPLv2 + classpath exception. We haven't updated the code yet, but this is coming very soon. I would anticipate the next official release should contain this new licensing scheme. In the meantime, keep an eye on our incremental releases:

Either the next one, or the one following will likely have this change.

thanks, Owen

Hey Owen,

That is great news! So if I am understanding correctly, that will allow me to specify the sgs-server-api as a maven dependency without dropping the MIT licensing on my game?

Thanks, Malachi de Ælfweald

Yes that is correct. The classpath exception should free you from the requirement of using GPL for any linked code.

Based on that, I decided it was time to move forward with the darkstar-based projects...

Since I have a Hudson server, I decided to let it keep track of how to make it successfully build...

At first I was trying to build with JDK7, but it kept failing on the Javadoc module saying that the jars had invalid characters in it. That went away once I changed to JDK6. I also had to tell it to skip the tests, because one of them just hung forever...

The Hudson job for the server is here.
The Hudson job for the client is here.
The Hudson job for the maven plugin is here.

The distributables were delivered to Nexus.

I created a new user on the server ('darkstar'/'darkstar') and unzipped the

I then created a symlink (/home/darkstar/current to /home/darkstar/sgs-server-dist-0.9.10-SNAPSHOT)

I don't know if it is correct, but I made this SMF manifest for it.

Guess it's time to build an app...

Server Died

So I got home last night to find the server had power but was not responding (mouse, keyboard, ssh, anything). I tried rebooting, but it kept handing at "Hostname: serveris" and wouldn't go any further (even in single-user mode). I saw some chatlogs online that suggested adding '-k -a -d verbose' and using '/dev/null' to the answer of any questions (like /etc/system replacement)...

I tried that and got this far (see left)...

Looking around some more, I saw that if I changed the '-k' to '-kd' it would drop it into debug mode. At that point, I did the following:

[0] moddebug/W 80000000
[0] :c

This allowed me to see a few more details.... (sorry for the blurriness of the pic - it was about 3am)

After trying to find anything online that would help (and the IRC channel) I finally said screw it and decided I would reinstall opensolaris on the root mirror.

I downloaded the USB version of OpenSolaris 0906 111a, but evidentially my quad core machine does not have the option of booting from USB (WTF?). I reburned the CD version and installed it. One thing that confused me is that although my old system was 10/08 upgraded to 111a and the new version was supposed to be 0906 111a, it now says 101b.

Trying to boot the new one, it again hung. At a different position, but... I was starting to think it was a hardware problem. I let it try to boot overnight and the next morning it was finally at the login prompt... with the old install.

The logs showed that it had tried to load the Belkin UPS a few steps after where it locked up, so I unplugged the UPS. I went ahead and applied all updates and rebooted. It took about 5 hours for it to finally boot again (though it did). It still says I am using 101b and that there are no new updates.

The xVM instance is there and I was able to start it. The whole root zone however is gone. The ZFS partition is there, and empty. zoneadm doesn't show anything but global. So, I am going to try to recreate the global zone, but... I still don't know what happened. I am also concerned that it currently takes about 5 hours to boot.

Playing some music

So I wanted to listen to some music, but neither youtube or pandora were working (not sure why, they were yesterday)...

So I tried Songbird, which I use at work. It wouldn't work either:
Error: GStreamer error: Internal data flow error. Additional information: gstbasesrc.c(2234): gst_base_src_loop (): /GstPlayBin2:player/GstURIDecodeBin:uridecodebin1/GstFileSrc:source:
streaming task paused, reason not-linked (-1)

So I tried Rhythm, but it couldn't play anything either...

WTF? Right?
So I did this instead. Now I have music playing :)

Don't forget to escape the inner class

I think I have used Windows too long...

You have to escape the $ for the inner class :(
