Hi Team

Post discussion on this ML and at UDS-Q I've written up what I think
is the bug triage process we should be following for server bugs:

  https://wiki.ubuntu.com/ServerTeam/KnowledgeBase/BugTriage

I tested this during my triage session yesterday and it covered all of
the bugs that I triaged.

This is v1.0 - please review - happy to discuss changes and make
updates if people think that it needs improvement.

Cheers

James

Re: Byobu autostart from cron

Whisperity — 2012-05-19T19:26:09

byobu-enable only changes the user's configuration to automatically load
byobu after a shell was initiated. However, as described earlier:

Do you try byobu-enable?

Byobu autostart from cron

Whisperity — 2012-05-19T14:04:37

Dear fellow Ubuntu users,

I have an automatation question I'd like to ask from you. My server runs
some servers which are, unfortunately, not daemons (like Minecraft or
Source Dedicated Server). I am planning on making them automatically start
at boot with the *< at >reboot* directive in crontab, but I wish their sessions
to be usable from *byobu*.

Problem being, that byobu does not auto-start. I have written a shell
script:

#!/bin/bash
screen -dr byobu -X screen -t srcds
screen -r byobu -p srcds -X stuff "./start_gmod.sh $(printf '\r')"

And I execute it as my *nonprivileged* user in *crontab*:

< at >reboot           sourcesrv                    cd /srv/srcds/orangebox
&& ./hook-byobu.sh

However, running this script requires *byobu* to be started when it runs.
If I test the script with starting byobu by hand and then executing it from
SSH, it does order byobu to make a new window and then starts the server.

My question being: can I, somehow, automatize the start of byobu into the *
hook-byobu.sh* file? I tried adding *byobu* (the command itself) after the
shebang-line, but then it hangs until I, by hand, F6 (detach) from byobu.

Turning byobu's *Start automatically after log in* on does not work,
because there is no login to happen, as the script is started from cron.

precise LIO target with iscsi support

Aleksi Handelofski — 2012-05-18T17:48:42

Hi All!

I saw that the kernel in precise brought support for the LIO target including the iscsi module.
So i wanted to know if the LIO iscsi support ist considered production ready or should we still use
the old and tested TGT?

Thanks for your opinions!

Alex

Hi,

yes but may be it is another typo:


An IP of 1213.203.209.160 in your default route does not exist in IPv4
;-). The 1213 is much too high ;-) and I think the 2 should be deleted.
But I also think your routing is not correct. In my opinion there should
be 113.203.209.163(the IP of your KVM host) instead of 113.203.209.161
and 113.203.209.0 instead  of 1213.203.209.16.
But these are only guesses and it depends on how routing is done in your
data center. (I think you are using Hetzner and Hetzner does not allow
you to use their gateway with other MAC addresses than your KVM host!) 
Maybe it is a typo but may be not because you used the command "route -n".

If you realy want some help you should post config files! It is easier
to track problems.

Hi Evan,

Can you elaborate a little more on getting "a webpage error" please?
What kind of error is it? 404 or security?

[...]
If you look at convirt screen shots you'll notice Convirt has very 
little to do with libvirt.
Libvirt is great if you want to build your own management platform.

Convirt, on the other hand, IS a management platform.

Thanks for pulling this together James,  it fits nicely into our need to
automate away a lot of the mindless manual part of tracking the release.
I've gone ahead and created a WIKI page to summarize your template [1],
and will be starting off a wider discussion on this beyond the server
team.  We've got too many half followed ways of tracking the status of
features [2][3][4], and until we standardize, automation isn't going to
happen effectively.  

Thierry's points are valid about the lack of history on the whiteboard
section,  but folks can subscribe to the blueprints they're interested
in and monitor, so I don't consider this a blocker.  Certainly its
something we'd like to see improved in Launchpad, but lack of this
logging shouldn't stop us from trying to get this standardization and
built in quality going forward.  ;)  Getting a common set of
keywords/phrases established and folks thinking about the problem from
the viewpoint of how do we test this,  how will it appear to the user,
has to be an improvement on where we are today.    

A good initial target will be generating the release notes for our
features [5] as they get completed.  A combination of standard location
to look for (ie. "Release Notes:"),  accurate status (blueprint "Done"),
linkage of related features together (via
topic-quantal-server-release-notes) to ReleaseNotes/UbuntuServer -
should enable a nice bit of this automation.   I'll make a point of
moving the blueprint for the release note automation[5] into this new
blueprint format tomorrow. ;)   I do plan on citing [6] though in any
discussion, since that example is how like most will need to look
like. ;)

Thanks!

MAAS Install issue

Evan Jones — 2012-05-15T19:17:33

I have downloaded the newest Ubuntu server iso image and have problems with
setting up the cloud. Here is what has happened so far.

 

Using a VMWare 4.0 server as the install platform.

 

Attempt #1

.         created controller on VMWare server. Install went smooth with no
problems. IP address for MAAS controller was 192.168.1.9 (from network DHCP
server -Endian firewall).

.         Created maas superuser as per instructions. Worked correctly.

.         Opened IE9 on Win7 desktop and went to MAAS page 192.168.1.9/MAAS
as per instructions. Page opened correctly.

.         Performed sudo maas-import-isos. Worked correctly.

.         Created 2 nodes in VMWare. Installed correctly. Nodes shut down
correctly.

.         Opened IE9 on Win7 desktop and went to MAAS page 192.168.1.9/MAAS
as per instructions. Page opened correctly.

.         Attempted to "Accept and Commission" nodes. System hung on me. I
had to shutdown controller and reboot.

.         Could not get back to MAAS Admin page at 192.168.1.9/MAAS.

.         Deleted all VMWare machines from disk and inventory on VMWare
server and started over.

 

Attempt #2 through--------

 

Did all of the same as above. When I tried to open the webpage at
192.168.1.9/MAAS or any other IP address that I tried during various install
attempts I would get an webpage error. If I entered just the controller IP
address I would get the Apache 
IT WORKS" but there is no content loaded for this webpage notice.

 

I have tried this with several different IP addresses, on a bare metal
machine, a different subnet on the network and with Firefox, Chrome and IE 8
and IE 9 on different desktop machines. Every attempt has provided the same
response: If I entered just the controller IP address I would get the Apache
IT WORKS" but there is no content loaded for this webpage notice. If I enter
the ip/MAAS address I get a webpage error.

 

I have even re-downloaded the Ubuntu 12.04 iso image and tried all over
again. Same problem.

 

What am I missing?

Thanks.

 

Evan

Re: resolv.conf

Márcio Santos — 2012-05-16T21:30:16

Hello Moretti.

I am assuming you are using Ubuntu 12.04.

There has been a change in the way the system creates the resolv.conf file.
If you have a static network configuration, you need to put your DNS
Servers configuration in the /etc/network/interfaces file with the
following entries:

        dns-nameservers x.x.x.x
        dns-nameservers x.x.x.x

On restart, the system will automatically populate the contents of the
resolv.conf file with the entries in the interfaces file.

Hope this helps.

Márcio
