Dear all,

after searching for a long time I guess I found that inode64 on XFS with
kernel 2.6.27 (shipped with openSUSE 11.1) is incompatible with NFS.
Sorry if this was already know, it wasn't for me and finding the problem
was complicated.

This is my nfs4 root (fsid=0):

# ls -li
insgesamt 0
4666 drwxr-xr-x 2 root root 48 15. Nov 19:54 daten
4668 drwxr-xr-x 2 root root 48 15. Nov 19:54 download2
4667 drwxr-xr-x 2 root root 48 15. Nov 19:54 dvd-images
4661 drwxr-xr-x 2 root root 48 19. Nov 06:51 mailsrv-backup
4669 drwxr-xr-x 2 root root 48 15. Nov 19:54 q
4670 drwxr-xr-x 2 root root 48 15. Nov 19:54 z

Then I mount those subdirs (mount --bind ....) to fill it with the dirs
I want to share:

# ls -li
insgesamt 20
256 drwxr-xr-x 14 root root 4096 19. Nov 03:01 daten
6454034730 drwxrwx--- 3 zmi users 61 26. Mär 2009 download2
4070671 drwxr-xr-x 2 root root 76 13. Nov 12:17 dvd-images
6500330752 drwxr-xr-x 5 root root 4096 8. Nov 04:31 mailsrv-backup
8591091465 drwxr-xr-x 17 root root 4096 12. Nov 02:01 q
2147483904 drwxrwx--- 31 zmi bh 4096 7. Nov 09:58 z

The shares "daten" and "dvd-images" can be mounted from other servers. I
simply went to the original dirs of this mount-bind, and created several
new dirs:
mkdir 1 2 3 4 5 6 7 8 9
and one of them had an inode < 2G, so I moved the contents there and
renamed the dirs, remounted the --bind mounts and now have this:

# ls -li
insgesamt 20
256 drwxr-xr-x 14 root root 4096 19. Nov 07:22 daten
184637244 drwxr-xr-x 3 root root 61 19. Nov 07:30 download2
4070671 drwxr-xr-x 2 root root 76 13. Nov 12:17 dvd-images
960533297 drwxr-xr-x 5 root root 4096 19. Nov 07:27 mailsrv-backup
184190222 drwxr-xr-x 16 root root 4096 19. Nov 07:41 q
184637237 drwxr-xr-x 30 root root 4096 19. Nov 07:42 z

And everything mounts fine now.

(I still have one server that can mount, but not write, to such a share,
but that may be another problem)

Just to let others know that can be a problem.
