Hi all,
Has anyone encounter the problem like this?
1. If a user replace a file (which on the Filer) using cp command using Solaris 8 machine such as;
# cp newfile oldfile
2. Then, on Linux server(NFS Client) A , reading the file, the file is new one.
3. But on another Linux server B, reading same file above, the file is stil OLD.
We experienced many times on many files and Linux servers. I suspect some linux cache behavior (attribute caching?), but This situation still remain after a few days...
[Our mount options] rw,nosuid,bg,soft,rsize=8192,wsize=8192,timeo=11,retrans=5
[Our Linux (all)] kernel 2.4.20, based on RHL 7.3
[Filer] F825, NetApp Release 6.3.3D2
I've read Technical report written by Chuck Lever(TR3183), noct and/or noac options may help, but I don't know why such long time Linux does not see a new file.
Anyone? Thanks,
