Hi List !
Since upgrading to Kernel 2.4.22-xfs (direct from SGI-CVS) I get this
problems, during bigger file NFS-copying (local XFS ->
remote NFS-based filesserver (also completely in XFS).
Nov 7 17:20:02 pc2 kernel: nfs: server server not responding, still trying
Nov 7 17:20:02 pc2 kernel: nfs: server server not responding, still trying
Nov 7 17:20:02 pc2 kernel: nfs: server server OK
This is my Test-Setup:
server: 64GB XFS-fs on ICP-Vortex (Hardware Raid5) SCSI controller
I tried everything, mentioned on the NFS FAQ Page to avoid this problems.

This Kernel 2.4.22-xfs is in case of NFS performance the worst since 2.4.7 and
reiserfs or the userspace
nfs daemon.
How can we stop the problem ?
Any ideas ?
TIA !
