uguali sulle due macchine a meno del parametro ucast che e'
chiaramente su alessandra l'ip di eth1 di lalla e su lalla quello di
alessandra.
i drbdx sono in /etc/fstab con l'opzione noauto.
Se spengo fisicamente il master (alessandra) o tiro giu' a manina
heartbeat lalla immediamente fa il take over e si prende tutto il
malloppo senza dire ne a ne b
il drbd switcha di ruolo senza nessun problema, idem al riavvio o all
restart di heartbeat.
Pero'...
se Io simulo un guasto di rete (I.E. uno switch che va arrosto)
unpluggando la scheda di rete eth1 su alessandra mi appare nei log di
lalla questa cosa

May 30 09:33:13 lalla heartbeat: [3018]: WARN: No reply to standby
request. Standby request cancelled.
e ovviamente non va su niente ne ip ne servizi.
dato che restuisce errore 1 ho provato a cercare con google ma o sono
un tordo integrale e non capisco nulla o nessuno sa cosa sia questo
errore 1 che e' definito errore generico.
indipendentementte da come sia definito pero' vorrei capire cosa sbaglio.
come ulteriore informazione aggiungo:
distribuzione etch con pacchetti backport
drbd 8.0.11 compilato staticamente nel kernel
kernel 2.6.25
heartbeat 2.1.3
Qualche idea da darmi?
grazie in anticipo e scusate il crossposting.
