a 7168GB volume - space resv = volume
in that volume, a 5325GB LUN with space resv enabled and frac resv set to 0%
LUN is presented to ESXi and the full capacity is formatted for the datastore
Datastore shows Capacity = 5.20TB
Yet when I run DF I get:
Filesystem total used avail capacity/vol/Volume01_vol/ 7168GB 3414GB 3753GB 48%/vol/Volume01_vol/.snapshot 0B 300GB 0B 0%
Why is my USED not 5TB... I have two other similar vols/LUNs in prod as well yet they are showing the 5TB Used in DF.... what am I missing here?
Filesystem total used avail capacity/vol/Volume01_vol/ 7168GB 3414GB 3753GB 48%/vol/Volume01_vol/.snapshot 0B 300GB 0B 0%/vol/Volume02_vol/ 7168GB 5474GB 1693GB 76%/vol/Volume02_vol/.snapshot 0B 347GB 0B 0%/vol/Volume03_vol/ 7168GB 5140GB 2027GB 72%/vol/Volume03_vol/.snapshot 0B 0B 0B 0%
Does it maybe have dedup or compression enabled ? otherwise as long as the LUN have space reservation. i would have the same expectation as you.
