Witam,

Dla naszego serwisu e-commerce mamy oddzielny serwer dedykowany dla bazy sql - jest to serwer HP 1U z dyskami SSD M4 Crucial 128 MB w raidzie softwerowym 1.

Serwer obsługuje Debian 64.

Od wczoraj jest nagły problem, ciągle wypisuje coś w typie "Cant read from swap" z tysiącami numerów linii.

Co to może być?

Jak serwer zresetuje w serwerowni to chwilę działa i znowu klapa.

Zawieszenie popoduje brak dostępu przez ssh.

Użyłem komend czyszczenia logów.

Czy jakiś czache się zapchał czy to jakaś usterka?

Proszę o pomoc!
Mogę dać mocny link w tym serwisie na ok 2 mln podstron.

Przydałby się szczegółowy opis błędu. Sprawdź dysk, jeżeli będzie ok, sprawdź RAM. Możesz też zawsze spróbować zrobić numer z swapoff, mkswap i swapon.

Zacny przyjacielu, jestem troszkę zielony, komendy wpisuję po literce z kartki.

Jak mogę sprawdzić ten ram i dyski? Czy wyjąć czy jakaś komenda na to jest?

Mamy tam 2 lub 4 GB ramu. Serwer jest nowy http://www.powerserver.pl/d7189_196421061777188.html

Dwa dyski Crucial M4 128 GB w Raid 1 softerowy + 250 GB Sata

Jak zrobić ten "numer" z swapoff, mkswap i swapon

Czy są na to jakieś komendy? Będę musiał tam pojechać bo jak resetuje to zanim wrócę to już się zawiesza.

Najlepiej zwróć się do kogoś kto w miarę ogarnia system (może ten kto Ci go zainstalował)? Samemu bym nie grzebał, jeśli za bardzo nie czujesz się w temacie. pokaże Ci gdzie masz zamontowaną partycję swap (linijka "/dev/md0 none swap sw 0 0" oznacza to że masz ją zamontowaną pod /dev/md0). Na początek bym proponował taki numer: W tym miejscu nie powinieneś mieć żadnych błędów, jeśli nie ma to: Robisz to jednak na własne ryzyko (chociaż nic nie powinno się stać, chyba że pomylisz urządzenia i /dev/md0 nie będzie partycją swap, ale np. głównym filesystemem)

Serwer działa ok i nagle się dzieje takie coś

sam sobie odpowiedziałeś, dysk sdb padł



wg fstab masz obecnie wyłączony swap na sdb czyli powinno działać (swapon -s dla sprawdzenia). Na przyszłość zrób swapa na raidzie to nie będzie problemu, że nie wspomnę o dorzuceniu ramu.

Hmm odnaleźliśmy takie cudo dla dysków Crucial M4 - działają tylko 5000 godzin a po tym czasie jeśli przekroczy w pracy 15K to się resetuje sam. Taki mały błąd firmware chipseta w Crucial M4 na cały świat. Nasz chyba właśnie coś koło tego jakiś6 miesiąc działa.

Po update software do 000F serwer widzi dyski ale gdy się włącza po wyborze F10 - F12 pisze Chacking Ram i nagle nic, ciemna plansza i migający po lewo u góry kursor.

Zmiana firmware miała nie kasować danych, wykonana była Windows 7 updater http://www.crucial.com/support/firmware.aspx

Co to może być?

Już ok, to był błąd Crucial M4 5000 godzin i finisz.
