tof:computer:vserver:upstart_ubuntu_lucid [09/06/2010 15:17] – status of stopping vserver Christophe Boyaniquetof:computer:vserver:upstart_ubuntu_lucid [13/07/2010 11:58] (Version actuelle) Christophe Boyanique

-Stopping the vserver does not (yet) work correctly: init do not stop services and all processes are killed after a timeout by vserver utils: 
-<code> 
-# vserver <vservername> stop 
-A timeout occured while waiting for the vserver to finish and it will 
-be killed by sending a SIGKILL signal. The following process list 
-might be useful for finding out the reason of this behavior: 
- 
----------------------------------------------------------------------- 
-15816   153 <vservername>  ?   Ss   0:00 /sbin/init 
-15835   153 <vservername>  ?   Ss   0:00 dbus-daemon --system --fork 
-15838   153 <vservername>  ?   Sl   0:00 rsyslogd -c4 
-15847   153 <vservername>  ?   Ss   0:00 /usr/sbin/sshd 
-15955   153 <vservername>  ?   Ss   0:00 atd 
---------------------------------------------------------------------

-The vserver can be stopped cleanly by going to level 0 in the vserver: 
-<code> 
-vserver <vservername> exec telinit 0 
-</code>

-Missing of ''/dev/console'' makes all scripts with ''console output'' fail:+Missing of ''/dev/console'' makes all scripts with ''console output'' fail. First think would be to create the ''console'' device inside the guest but this should be avoided: 
 <code> <code>
-# mknod --mode=600 /etc/vservers/<vservername>/vdir/dev/console c 5 1+19:57 <@Bertlwell, regarding console: you probably don't want 'the console' created inside a guest, because that means that  
 +               upstart (from the guest) will write on your host console (and can read stuff from there too) 
 +19:58 <@Bertl> what you want is to put a tty or pts there instead of the console, or if you like to see the output on the  
 +               current tty just tty
 </code> </code>
 +
 +I use ''tty'' so the console outpouts on the current tty:
 +
 +<code>
 +# mknod --mode=600 /etc/vservers/<vservername>/vdir/dev/console c 5 0
 +</code>
 +
 +
 +If you want to troubleshot from outside the vserver you can use for example ''tty8'' as the console device for vservers:
 +
 +<code>
 +# mknod --mode=600 /etc/vservers/<vservername>/vdir/dev/console c 4 8
 +</code>
