NFS Filesystem DF Usage ??

[MikeL_4]

We are runninf Red Hat 5.5 on several servers, with one server being an NFS server and sharing file systems out to other servers..

Issue is the client has noticed that a df -k on a file system on serverA, may report different usage than on serverB...
On serverB:
=> df -k .
Filesystem 1K-blocks Used Available Use% Mounted on
serverA-p:/appsoftware
10321216 7080480 2716448 73% /apps

On NFS ServerA:
=> df -k .
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/mapper/datavg-lvol2
10321208 7080532 2716388 73% /appsoftware

On serverC:
=> df -k .
Filesystem 1K-blocks Used Available Use% Mounted on
serverA-p:/appsoftware
10321216 7080832 2716096 73% /apps

How often do file system stats get updated across the NFS clients with the NFS server ??

or will these always be off some due to activity on the file system across the different clients ??

Yes . There will always be differences specially if your NFS share is very dynamic.. lots of activities etc
