Witam, przywiesił mi się w jakiś dziwny sposób serwer. Od razu dodam, że na serwerze nic nie było zmieniane w ostatnim czasie, a jego uptime wynosił ponad 180 dni.
Na pingi nie odpowiadał, tracert nie dochodził do serwera, a usługi uruchomione na portach (np. nginx) raz się wczytywała strona, raz nie (częściej jednak nie). Początkowo to wyglądało na jakieś problemy z siecią, ale..
Postanowiłem wykonać reboot sprzętowy, ale przedtem w konsoli VNC zauważyłem takie coś:
Po wykonaniu tego reboota sprzętowego, serwer zaczął śmigać bez żadnych problemów. Jednak przyznam szczerze, że serwer długo się uruchamiał (w konsoli VNC zauważyłem, że długo "stał" na uruchamianiu NTP).
Czym może być spowodowane takie zachowanie serwera? Sieciówka już nawala, czy może inny problem sprzętowy, np. dyski?
Prześle jeszcze smart dysków:
