DF Output - LUNs

nicholsongc — Wed, 04 Jun 2025 13:39:51 GMT

I have:

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%

Thank you!

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.
