(gelöst) avahi mounter geht nicht mehr

mk75 · February 15, 2015 at 5:28 PM

Hallo,
Ich hatte ein funktionierendes Client/Server System in dem beide "von alleine" sich gegenseitig ihre Aufnahmeverzeichnisse angezeigt haben.
Irgendwann um Weihnachten herum, nach dem ich ein Update gemacht habe hat es "von allein" aufgehört zu funktionieren.
Ich erinnere mich das es damals während des Updates ein Problem mit dem NFS gab
aber sonst nichts auffälliges.
Momentan ist bei Client / Server apt-get update und dist-upgrade vollständig durchgelaufen.

Ich bin jetzt soweit mit der Fehlersuche das ich das Problem im Server vermute.

Das spricht das log vom "client":

Code

Beim Server passiert jedoch gar nichts:

Code

root@vdr3:/home/markus# tail -n 2000 /var/log/syslog | grep avahi

Erst wenn ich den Service Starte erhalte ich ein Output:

Code

root@vdr3:/home/markus# service avahi-mounter start
avahi-mounter start/running, process 2667
root@vdr3:/home/markus#

Feb 15 17:18:11 vdr3 avahi-mounter[2669]: mount static to /srv/vdr/video.00

Aber es geht immer noch nicht.
In einen anderen Thread wurde geraten den Avahi Manuell zu starten, beim Client passiert nichts, beim Server erscheint
folgende Fehlermeldung:

Code

Gibt es vielleicht irgendetwas wie ein einfaches "reinstall" ohne das man alle seine Einstellungen usw. verliert ?

Mein Frau meckert schon täglich das wir vom Server nichts mehr abspielen können. Mittlerweile kopiere ich die
Filme vom Server die sie sehen will per scp vom Server auf den Client....

mini73 · February 22, 2015 at 10:26 AM

Auf dem Server muss der avahi-daemon laufen und eine passende service-Datei in seinen Einstellungen haben. Dann dürfte der avahi-mounter in automatisch finden, wenn er startet.

Alternativ kannst du ja auch mal versuchen, auf den avahi-linker umzustellen, da gibt's hier im Portal irgendwo eine Anleitung von seahawk1986.

mini73 · February 22, 2015 at 10:29 AM

Wenn man /home und /srv bei der Installation auf eigene Partitionen gepackt hat, muss man nur die eigenen templates und diverse Dinge unter /var/lib/vdr und /etc/vdr sichern, dann kann man meistens gefahrlos neuinstallieren. Aber niemals ohne Backup!

Und beim Zurückspielen der vdr-Konfiguration erst den vdr stoppen.

seahawk1986 · February 22, 2015 at 11:08 AM

Hast du mal nachgesehen, ob dbus und der avahi-daemon überhaupt erfolgreich gestartet werden können? Der Trace vom avahi-mounter sieht ja eher so aus, als ob da schon etwas auf der Ebene nicht klappt.

mk75 · February 23, 2015 at 8:07 PM

Hallo,
ja dbus startet:

aber von avahi überhaupt nix:

Code

root@vdr3:/home/markus# tail -n 3000 /var/log/syslog | grep avahi
root@vdr3:/home/markus# tail -n 3000 /var/log/syslog | grep avahi*
root@vdr3:/home/markus# tail -n 3000 /var/log/syslog | grep *avahi*
root@vdr3:/home/markus#

mini73 · February 23, 2015 at 8:12 PM

Grep doch mal ohne tail, vielleicht kommt es früher im syslog.
Einfach nur: grep avahi /var/log/syslog

Sternchen braucht es nicht.

Lars

mini73 · February 23, 2015 at 8:12 PM

Ansonsten: status avahi-daemon

Gibt es denn eine /etc/init/avahi-daemon.conf ?

mk75 · February 23, 2015 at 8:27 PM

Code

root@vdr3:/home/markus# more /etc/init/avahi-daemon.conf
/etc/init/avahi-daemon.conf: No such file or directory

Leider nein.

mk75 · February 23, 2015 at 8:32 PM

Code

-rwxr-xr-x 1 root root 341 Dec  6  2013 /etc/init/avahi-mounter.conf

Eine mounter.conf würde es geben.

DANKE.
Ich hab die avahi-daemon.conf vom client kopiert und schon geht es wieder !
