Avamar: GSAN degradert og server i synkroniseringstilstand
Summary: Avamar kan vise en degradert GSAN-status og en synkroniseringstilstand i mccli-serverens show-prop-kommando på grunn av høy metadatautnyttelse, vanligvis over 90 %. Dette problemet kan oppstå på grunn av feil sikkerhetskopiering, replikering til GSAN-et eller andre faktorer. Du kan løse dette ved å følge trinnene i Dells interne artikkel 000047627, som forklarer hvordan du reduserer metadatakapasiteten og eliminerer synkroniseringstilstanden. Når du har fullført disse trinnene, skal mccli-serverens show-prop-kommando vise Full tilgang i attributtet Tilstand. ...

Cause
Synkroniseringstilstand oppstår når det er høy metadatautnyttelse. I dette scenariet er metadatakapasiteten 99,91%:
admin@AVMR-SRV:~/>: mcserver.sh --status | grep metadata metadataUtilization (larger of (nstripes/totalStripesPermitted) or (stripeReserved/(nodeSizeAfterDiskReadOnly * stripeUtilizationCapacityFactor)) * 100): 99.91 admin@AVMR-SRV:~/>:
Scenariet ovenfor oppstod fordi en feil replikering til denne Avamar (GSAN) ble utført. Det er andre faktorer som kan øke metadatakapasiteten. Bruk denne artikkelen Avamar metadata kapasitetsoppløsningsbane for mer informasjon.
