Încercam să rulez o restaurare bacula, dar sa plâns de comunicarea la distanță-sd.
S-a dovedit că bacula-seed nu rula pe mașina gazdă. Serviciul a fost pornit, dar problema a continuat.
De aceea am încercat să testez biblioteca de benzi rulând mtx -f /dev/sch0
Mtx mi-a înghețat complet sesiunea. Procesul Mtx a fost vizibil de la ps, dar nu am putut să-l omor cu niciun kill sig. Serverul a fost repornit din nou.
Orice încercare de a folosi mtx blochează totul. Mai târziu am aflat că există o urmă în syslog.
