vol show xyz -field used --> 8.61TB, and total size assigned -->50TB ( NFS Volume)
However, on the linux client. df -h shows 24TB used. Size Used Avail Use% Mounted on 49T 24T 26T 48% /mount/xyz
This volume has "auto" tiering, and deduplication enabled. I believe the figure on the filer is accurate.
1. If it is, then why did Linux client show such large amount of difference?
2. how and what commands can tell me the accurate usage on Linux?
Thank you!

Odd. I'd open a case as we need a packet trace to see why it is doing that.

If I told you that this is in a cloud environment, the filer is CVO, and the Linux server is a cloud VM. Would that make any different to you?
I thought it wouldn't, that's why I didn't mention it earlier.

No it wouldn't.
