Symptoms

  • Nogle lagringssæt kunne tidligere ikke klone ved hjælp af et script eller automatisk.
  • "ghost"-lagringssæt kan vises uden diskenhedsnavn med mminfo (se nedenfor).
  • Kontrollér, at destinationsfilsystemet viser filen saveset, men IKKE "notes"-filen.
  • Scannerkommandoen for saveset mislykkes (se nedenfor).
  • Yderligere forsøg på at klone saveset mislykkes ved fejl: Err: 5004-nfs lookup failed (nfs: Ingen sådan fil eller mappe)
mminfo CLI-output viser mislykket lagringssæt af klon med "E"-flag: 
# mminfo -q ssid=928093938 -r ssid,cloneid,ssretent,clretent,ssflags,clflags,copies
ssid         clone id retent  clretent ssflags clflg copies
928093938   1532073714 08/24/2018 08/20/2018 vrF         2
928093938   1532252170 08/24/2018 08/24/2018 vrF   E     <--- This is the incomplete clone.

Når vi tilføjer "diskenheds"-switchen, rapporteres der imidlertid kun 1 linje: 
# mminfo -q ssid=928093938 -r ssid,cloneid,ssretent,clretent,ssflags,clflags,copies,volume
ssid         clone id retent  clretent ssflags clflg copies volume
928093938   1532073714 08/24/2018 08/20/2018 vrF         2 source-volume-name
                                                         ^ ---2 copies yet only 1 shows in the output.

Cause

DD har fastholdelseslås aktiveret. Dette forhindrede, at det ufuldstændige oprindelige lagringssæt blev fjernet, og forhindrer det næste kloningsforsøg i at overskrive dataene i destinationsstien.

Resolution

Løsning:

I scannerforsøget ovenfor skal du finde stien til saveset på destinationen: 
//nw-server-name/destination-device-path/08/04/notes/705d0dc6-00000004-5982f3fd-599ed855-190c442c-4c9896fd

Vi har brug for stien til selve savesettet, som vil være et niveau over "noter", f.eks.: 
//nw-server-name/destination-device-path/08/04/

Tilføj derefter DD mTree-stien, der altid starter /data/explorer1/mtree-navn. "mTree list" på DD CLI viser de MTrees, der er konfigureret. MTree-navnet svarer typisk til værtens NetWorker-servernavn. Tilføj derefter det lange navn for saveset til sidst.
Så i dette eksempel bliver den fulde sti til: 
/data/col1/nw-server-name/destination-device-path/08/04//705d0dc6-00000004-5982f3fd-599ed855-190c442c-4c9896fd

Vi skal bruge denne sti til at deaktivere opbevaringslåsen på destinationens Data Domain-system:
  • På destinationen DD CLI skal du køre: mtree retention-lock revert [path](sti fra oven). Dette anmoder om sysadmin-adgangskoden. 
  • Klon saveset igen - dette burde nu fungere uden fejl, fordi det nu kan skrive til destinationsstien.
  • mminfo-forespørgsler til klonede lagringssæt bør nu fungere korrekt.
  • Gentag dette for alle andre berørte saveset.
