While mounting NFS share from EMC celerra (NX80G v5.6) which has file system level quota on the NAS, the client sees the size of the entire file system on NAS and not the quota. This is very misleading on the client side where the users assume there are a lot space available on the system than it is (from the df command). To fix this issue, the following parameter on the NAS needs to be enabled to show the quota size instead of file system size: # server_param <server_name> -f quota –modify useQuotaInFsStat –value 1 Display current value: # server_param <server_name> -f quota –I useQuotaInFsStat
