Server is 2.6.23-rc9 and is exporting: /dirA/dirB 10.10.20.0/255.255.255.0(rw,async,no_root_squash,no_subtree_check,insecure,crossmnt) /dirA/dirB/dirC 10.10.20.0/255.255.255.0(rw,async,no_root_squash,no_subtree_check,insecure) /dirA/dirB/dirD 10.10.20.0/255.255.255.0(rw,async,no_root_squash,no_subtree_check,insecure) The NFS client (Core2 SMP) 2.6.24-rc3-git4: NFS-server:/dirA/dirB /dirA/dirB nfs auto,rsize=16384,wsize=16384,hard,intr,users,exec,nfsvers=3,tcp,nolock,actimeo=0 Then on the client when the new kernel has booted: ls /dirA/dirB --> normal listing ls /dirA/dirB/dirC --> Stale NFS file handle ls /dirA/dirB/dirD --> Stale NFS file handle I will do a few more builds/boots and check -rc3-git2 and -rc3-git3.
