Symptoms

NetWorker VMware Protection (NVP)-integrationen er konfigureret med vProxy-enheden. Sikkerhedskopieringerne af den virtuelle maskine (VM) mislykkes, og NetWorker-arbejdsprocesloggen viser: 
MM/DD/YYYY HH:MM:SS [VM_NAME]: Unable to start backup on vProxy '[VPROXY_NAME]': Received an HTTP code: 500, libCURL message: "", vProxy message: "Error received from vProxy ="-500: Panic occurred: runtime error: invalid memory address or nil pointer dereference".

Cause

Filsystemet /data01 er fuldt monteret på vProxy-enheden. Lageret forbruges af logfilerne for sikkerhedskopieringssessionen, som findes i mappen "/opt/emc/vproxy/runtime/" (findes i mappen /data01) og som standard opbevarer dem en måned. vProxyen kan ikke skrive sessionslogfiler for at starte en sikkerhedskopiering.  
myvproxy:/data01/runtime/logs # df -h

Resolution

vProxy-enheden kan geninstalleres for at rydde de eksisterende logfiler. vProxyen indeholder ingen oplysninger, der er nødvendige for at udføre gendannelser af data, som allerede er blevet sikkerhedskopieret. 

Additional Information

Der kan frigøres plads på vProxy-tilslutningspunktet /data01 ved at slette logfiler fra: /data01/runtime/logs/recycle/

Her er et eksempel på en procedure til oprettelse af et cron-job, der sletter de logfiler, der er 14 dage gamle:

  • Log på vProxy over SSH som admin, og skift derefter til rod: sudo su - root
  • Opret et crontab-job til rodbrugeren med: crontab -e
  • Indsæt følgende linje i teksteditoren for at slette sessionslogfilerne, der er ældre end 14 dage hver dag kl. 6:
* 6 * * * find /opt/emc/vproxy/runtime/logs/recycle/vbackupd -type f -mtime +14 -delete
  • Se indholdet af det nye root-bruger cron-job med: crontab -l
  • Antallet af dage, hvor logfiler skal opbevares, kan ændres for at forhindre, at filsystemet når op på 100 %.
BEMÆRK: Disse ændringer overføres ikke under en vProxy-opgradering.
