I have a NFS server configured on FreeBSD 9.0 Beta2 that only serves a
share through NFS v3 TCP. All the processes ( mountd, rpcbind, lockd,
etc ) are started with -h <local ip> on both the server and the clients.
The NFS clients range from FreeBSD 6.1 to 8.2.
On all the clients, it is impossible for me to erase a directory that
contains other data and is from that NFS share. I get this error:
rm -rf nick/
rm: fts_read: Input/output error
same is true if I give the full path:
rm -rf /usr/nfs.mount/nick
rm: fts_read: Input/output error
if the directory is empty, I can use rm -rf or rmdir without problems.
Besides this I can read all the files, erase files, chmod, chown, etc
without any problem. I just can't erase directories.
Running a truss on the rm -rf shows ( towards the end ):

There are no errors visible on the server.
Here is the output of nfsstat on the server:

Anyone has any ideas what might be causing this ?
