Ondanks dat DFS erg robuust is en wereldwijd veel word ingezet, wil je toch graag de mogelijkheid om DFS te kunnen monitoren/controleren. Dit kan vanuit onze TiC dienst met een compleet DFS script maar niet iedereen maakt (nog) gebruik van deze dienst. Derhalve kwam ik vandaag onderstaand PowerShell script tegen welk erg handig kan zijn wanneer je je eigen monitoring oplossing uit wil breiden met DFS monitoring.

Vandaag een leuke ervaring rijker met DFS. Ik heb hier in het verleden veel mee gewerkt maar nog niet veel met de 2008R2 variant. De ervaring leert dan ook dat er erg veel over is te vinden op het internet maar wat is nu accuraat, wat is nog relevant. Onderstaand is van toepassing op 2008R2.
In het algemeen over DFS. DFS is een oplossing om data van meerdere servers centraal aan te bieden. Dit maakt 2 dingen mogelijk als speerpunt mogelijk, één er is niet één grote server welke bijvoorbeeld alle data moet aanbieden en dus een single point of failure is. Maar ook dat wanneer de data over meerder servers word verspreid het voor een eindgebruiker wel als één server over kan komen.
Denk aan het voorbeeld dat uw “S” schijf (een simpele data schijf) nu zowel foto’s, autocad tekeningen en de gebruiker data bevat. Dit is niet altijd zomaar uit elkaar te trekken zonder veel overlast voor een eindgebruiker. Met DFS is het mogelijk dit wel te doen, toch alles onder de S schijf te houden maar de data vanaf meerdere servers aan te bieden. Waarbij de ene bron een 2008 server is, de 2e bron een 2012 server en de 3e bron (t.b.v. foto’s) een NASje op het netwerk is welke direct aangesproken word. En dit alles word weergegeven als één schijf / drive-letter.
