Re: [Xen-users] Debian 7.7 xcp-xapi doesn't start on boot

[Mark Benson <md.benson@xxxxxxxxx>]

Solved. I hadn't eradicated xendomains from the startup. The xendomains init file has changed names from:

/etc/init.d/xend

to

/etc/init.d/xendomains

Lord knows how dpkg-reconfigure got around that, but hey ho. Thanks for your help. It made me rethink the process from scratch and I got to a solution!

Thanks. They only list developer mailing lists on xenserver.org. The CSS doesn't load on the support forums and they are all kinds of messed up for me, not sure why :\

After a fresh reboot this is what I see:

root@zaire:~# service xcp-squeezed status

[ ok ] squeezed is running.

root@zaire:~# service xcp-xapi status

[FAIL] xapi is not running ... failed!

root@zaire:~#

I did read the notes for that bug but squeezed seems to be working okay. Also if I ONLY run

dpkg-reconfigure squeezed

then

service xcp-xapi start

it still won't start. The xcp-squeezed is probably a red herring, I just found those reconfig instructions on the Xen Orchestra blog and decided to give them a shot, and suddenly it worked.

In fact I found subsequently only

dpkg-reconfigure xcp-xapi

is required and it starts up. Yet

service xcp-xapi start

on it's own doesn't work and fails to start (as I assume it does on startup), so something in the dpkg script is magically curing (more likely fudging or forcing an override of) the issue.

Indeed, shockingly it's in /var/log/xcp-xapi.log :P

I've flushed out the logs and produced some clean outputs:

Failed at boot:Âhttps://www.dropbox.com/s/eow388i494kh317/xcp-xapi.log.5?dl=0

Failed after boot:Âhttps://www.dropbox.com/s/oprsg9pz0mlfxb3/xcp-xapi.log.3?dl=0

Successful during/after dpkg-reconfgure:Âhttps://www.dropbox.com/s/ty6atht1rufwc1h/xcp-xapi.log.4?dl=0

As best I can see the issue initially is some kind of V6D error. Any subsequent retries seem to choke on not being abler to bind the service to 127.0.0.1:80 which would seem to me that the process is choking up the port. I also found this when I looked after a fresh boot:

root@zaire:~# ps ax | grep xcp

Â4095 pts/2 Â ÂS+ Â Â 0:00 grep xcp

No idea if that's normal or not, but there seems to be a lot of stunnel processes.

Appreciate any input.

xcp has effectively been subsumed by the OpenXenserver project which has
it's lists/wiki etc over at www.xenserver.org, which is probably where
you will find the most help.

Disclaimer: I know next to nothing about any of this. But given that
reconfiguring squeezed seems to be related does "service xcp-squeezed
start" before starting xcp-xapi start?

Googling "xcp-xapi missing table" also threw up:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=682202 which I don't
even remember filing!

I'd expect them to be under /var/log somewhere...
