Cause

Het proces vm-file-extractor kan niet worden uitgevoerd vanwege een gebrek aan geheugen op het PowerProtect Data Manager zoekknooppunt. De minimale vereiste van het vrije geheugen is 800 MB. Het mislukken van het uitvoeren van vm-file-extractor heeft ervoor gezorgd dat de alleen-lezen bit niet goed is ingesteld. Dit leidt tot de foutmelding "Unable to reset disks to read/write mode after VSS quiesce operation set them to read-only."

Resolution

1. Meld u aan bij de PowerProtect Data Manager appliance met behulp van SSH, schakel over naar de rootgebruiker en voer onderstaande opdrachten uit om het wachtwoord van het PowerProtect Data Manager-zoekknooppunt op te halen.

source /opt/emc/vmdirect/unit/vmdirect.env && /opt/emc/vmdirect/bin/infranodemgmt get -secret -node_type SearchNode

2. Meld u aan bij elk zoekknooppunt met de referenties die u in stap 1 hebt gekregen.
3. Voer de onderstaande opdracht uit om het geheugengebruik van het zoekknooppunt te controleren.

free -m

4. Als het vrije geheugen inderdaad minder dan 800 MB is, voegt u meer geheugen toe aan het zoekknooppunt of start u het zoekknooppunt opnieuw op wanneer PowerProtect Data Manager inactief is om het toegewezen geheugen vrij te maken.
5. Voer de VM-herstelbewerking opnieuw uit.
