Symptoms

Når du deaktiverer deduplikering og komprimering på en VSAN-klynge, markeres en advarsel på VSAN Skyline Health for "Deduplikering og komprimering er aktiveret, men bør deaktiveres" for nogle eller alle diskgrupper

At udføre indstillingen "afhjælp inkonsekvent konfiguration" løser det ikke.

Deduplikering og komprimering er aktiveret, men skal deaktiveres

Deduplikering og komprimering er "deaktiveret" på klyngeniveau. På værterne er den dog aktiveret på diskniveau: 

# localcli vsan storage list | grep -E "^\w|Deduplicat|Compress"
naa.6000c29d3903f62e65db90e4a33c7113:
   Deduplication: true
   Compression: true
naa.6000c294ae2907d1eaccdabf00adad3b:
   Deduplication: true
   Compression: true
naa.6000c2950cfde25cd01bb892188cd5ca:
   Deduplication: true
   Compression: true
naa.6000c299347304271292f577d07f01f0:
   Deduplication: true
   Compression: true
I clomd.log på en vært vil der være hændelser relateret til Whatif-kontroller, der mislykkes.

Cause

Utilstrækkelig kapacitet til at understøtte fuld evakuering af en diskgruppe, samtidig med at redundans bevares.

Ved deaktivering af deduplikering og komprimering blev afkrydsningsfeltet "Tillad reduceret redundans" ikke markeret.
Så når en diskgruppe fjernes, forsøger VSAN at sikre, at der er nok kopier af alle komponenter til at sikre fejltolerance. Hvis redundans ikke kan sikres, kan processen ikke fuldføres.

Deaktiver deduplikering og komprimering med indstillingen Tillad reduceret redundans ikke markeret

 

Resolution

Genaktiver deduplikering og komprimering, og deaktiver den igen, men sørg for at markere afkrydsningsfeltet "Tillad reduceret redundans".

 

Deaktiver Dedup og komprimering Tillad reduceret redundans

 

 

ADVARSEL: Under processen med at deaktivere eller aktivere deduplikering og komprimering, med reduceret redundans tilladt, selvom tilgængelighed vil være sikret, vil der være midlertidige perioder med reduceret redundans for nogle objekter, da hver diskgruppe evakueres.
