Ausfälle des Datenbank-Servers

[frobi]

Hallo zusammen,

ich habe das Problem, das mein DatenbankServer immer wieder sporadisch kurz ausfällt.
Mein Hoster sagt mir nun das es am Speicher liegt und ich ein höheres Paket benötige.
Es kommt mir etwas seltsam vor und deshalb würde ich mich freuen, wenn jemand auf folgenden Log-Auszug einen kurzen Blick werfen könnte.
Vielen Dank im vorraus.

Hihi, verkaufsfreudige Jungs da, gell?

MySQL fällt halt ab und an auf die Nase und zerbröselt dabei. Deine InnoDB-Dateien scheinen defekt zu sein, das ist mehr oder weniger irreparabel. Versuche einen kompletten Dump zu ziehen (falls das noch geht), lösche dann MySQL, installier es neu und spiel den Dump ein. Ziehe regelmäßig Dumps und hebe diese auf, denn das wird sicher wieder passieren. Falls Dir das zu blöde ist, migriere zu PostgreSQL ;-)

 

[frobi]

Das habe ich mir auch eher gedacht.
PostgreSQL steht leider nicht zur Verfügung, ich muss also mit dem Leben was ich habe.
Gibt es ggf. ein Script/Tool welches ich per Cronjaob die Funktionalität prüfen lassen kann und ggf. reparieren kann?

Ich danke Dir für deine Info.

 

[akretschmer]

es gibt mysqlrepair. Davon abgesehen, daß es schon bezeichnend ist, daß es solch ein Tool gibt - das geht IIRC nicht bei InnoDB. Es gibt wohl auch ein mysqlcheck - Tool. Ich weiß aber nicht, wie das im laufenden Betrieb wirkt, also ob das z.B. Tabellen sperrt oder so.

Wenn ein Dump fehlerfrei durchläuft ist das aber schon mal ein recht sicheres Indiz, daß die DB ok ist. Bei MYISAM sperrt dies aber fröhlich Deine Tabellen ;-)

 

[frobi]

OK, ich schaue mir mal mysqlcheck genauer an.
Vielen Dank für die Info.
