NetWorker: Sikkerhetskopiering av katastrofeoppretting for klynge mislykkes i passiv node

Sikkerhetskopiering av filsystemet mislykkes for lagringssett for katastrofeoppretting, men fungerer for lokale stasjoner i en klynge med to noder.

Saveset C:\ og DR

Error:

99128:save:Disaster Recovery: critical volume C:\ClusterStorage\Volume1\ identified for disaster recovery backup has been created on a CSV volume. Backup of critical volume on CSV volume is not supported.

Dette betyr at noen applikasjoner er installert på CSV, derfor vurderer det CSV som kritisk stasjon.

save -o VSS:LCV=yes skal ikke oppgi CSV som kritisk volum på de fysiske nodene. Hvis CSV-filen er oppført som kritisk, mislykkes DR-sikkerhetskopieringen. I utdataene nedenfor (sjekk Notes-delen), se at CSV er oppført som kritisk på en node og fra en annen, det er det ikke.

Fjern det installerte programmet fra CSV-filen.

Utdataene kommer fra en av nodene i klyngen. Dette viser CSV som kritisk volum, og dermed fungerer sikkerhetskopiering for C:\ og mislykkes for DR-lagringssett fra denne noden.

The following volumes are determined as critical by the system state writers:
C:\ (disk num 0)
The following volumes are critical because they are parents for one or more mounted critical volumes:
The following volumes are critical because they are in the same dynamic disk pack with one or more critical volumes:
The output is from another node from Cluster which doesn't show CSV as critical volume and hence backup works for both C:\ and DR saveset.
