Subject: nfs caching problem

Hi Trond,

I already postet this problem a couple of months before to this list, but =

never got an answer. I think there's a serious problem with nfs caching in =

2.6.16 (don't know about other kernel versions yet, we never had this probl=
em =

with 2.6.11 and below).

Here the stat output for the same directory, just on two different systems:

bernd@zuse test-wine>stat /usr/local/wine
File: `/usr/local/wine'
Size: 344 Blocks: 0 IO Block: 8192 directory
Device: 18h/24d Inode: 168810 Links: 4

On sytem zuse stat is actually reading the information =

of /usr/local/wine.old-2006-11-13. I had just moved wine to =

wine.old-2006-11-13. =


bernd@zuse test-wine>stat /usr/local/wine.old-2006-11-13/
File: `/usr/local/wine.old-2006-11-13/'
Size: 344 Blocks: 0 IO Block: 8192 directory
Device: 18h/24d Inode: 168810 Links: 4
Access: (0755/drwxr-xr-x) Uid: ( 0/ root) Gid: ( 0/ root)
