vol 2.5TB (300gb free and space guranteed)
LUN 2.0TB (RDM full) (space reserve)
Snap Reserve 10% = 250gb?
Our LUN went offline when the vol got full. After deleting snaps by turning on autodelete, we now have 85% capacity according to df -h. Just enough for the dedupe staging process/logs exc.
So should I enabled dedupe or just manage snaps better? I had 10% snap reserve so I thought that would be 250GB (our vol has 300GB free) so I thought I was safe unless snap reserves are allowed to overcommit?
RDMs are essentially reserved. I spent two hours trying to read this Dedupe document attached but was confused on whether or not an RDM would benefit me with the settings you see above. pg.45 6.4.18
