Symptoms

Dette kan ske i enhver DD med Cloud Tier aktiveret.

Cloud-rengøring har ikke noget udnyttelsesfald, hvis der er mange GC-afventende cyklusser, der sidder fast for at behandle sletning af baggrund.

 

Cause

Hvis cloudenhedens timeouts er for hyppige, kan DD ikke behandle sletning i baggrunden.

EVT-CLOUD-00001: Unable to access provider for cloud unit edccloudtier2.EVT-OBJ::CloudUnit=edccloudtier2 EVT-INFO::Cause=Timeout was reached
EVT-CLOUD-00001: Unable to access provider for cloud unit edccloudtier2.EVT-OBJ::CloudUnit=edccloudtier2 EVT-INFO::Cause=Cloud profile state is DOWN

 

Resolution

Nedenfor er de mulige problemer, når en cloudenhed frakobles.

  1. DDFS går i en ikke-reagerende tilstand eller får panik.
  2. Dataflytning enten stopper eller afbrydes.
  3. Cloudrensning afbrydes eller renser ikke udløbne data fra Cloud Tier.
  4. Cloud-tilbagekaldelse fungerer ikke eller tager tid eller viser, at data ikke er fundet.

Cloudenheden viser ikke et udnyttelsesfald efter rensningscyklus, hvis flere ventende cyklusser er i en tilstand, der er holdt op med at reagere. Beviset kan ses i auto-support.

Følg disse trin i henhold til scenariet.

  • Tjek forbindelsen med cloud-udbydere, og se, om
    • Der er et problem med forbindelsen på porten(443)
    • Kontrollér navnestatus for cloududbyderen fra DD
    • Hvis alt er korrekt mellem DD og cloudniveau, skal du gå til DD og se, om filsystemet ikke reagerer eller har panik.
    • Genstart DD for at frigive eventuelle processer, der holder op med at reagere, for at få korrekt cloudforbindelse og behandle afventende GC-cyklusser.
  • Problemet løses ved at gøre skyforbindelsen korrekt og køre under kommandoer på DD for at stoppe og genstarte sletning af baggrund.
    Stop den asynkrone sletning 
    # cloud clean background-delete stop
    Genstart massesletningerne. 
    # cloud clean background-delete start
  • Fejl #234809 - Opgrader DD til 6.1.2.x, hvis du har mere end én cloudenhed og har problemer med cloudrensning.

 

Additional Information

Cloudenheden viser ikke et udnyttelsesfald efter rensningscyklus, hvis der er flere ventende cyklusser, der er i en tilstand, der er holdt op med at reagere. Beviset kan ses i auto-support.
