bad cookie size 20 (only cookies under 8 bytes are supported.)

[Marc Schmitt]

Hi all,

I did upgrade yesterday my RedHat 7.3 box (2.4.20-20.7smp) from 
nfs-utils 1.0.5 to 1.0.6, after that, messages was full with:

Nov  2 15:02:56 server kernel: lockd: bad cookie size 20 (only cookies 
under 8 bytes are supported.)
Nov  2 15:02:56 server kernel: svc: failed to decode args
Nov  2 15:02:57 server kernel: lockd: bad cookie size 20 (only cookies 
under 8 bytes are supported.)
Nov  2 15:02:57 server kernel: svc: failed to decode args
Nov  2 15:03:16 server kernel: lockd: bad cookie size 20 (only cookies 
under 8 bytes are supported.)

I've never had those messages before, does 1.0.6 require a certain 
minimum kernel version (ex. >= 2.4.22)?

TIA

Regards,
    Marc

Just wanted to add:
On the same token, I did have to move the exported files to a different 
partition. Before I did that, I asked all users to log out everywhere, 
so that no homes are mounted before I started moving the files. Could it 
be that this errors come from clients that try to lock "old" inodes?

I sent Trond a patch to fix this in March.  It's not your nfs-utils,
somebody on the network started a MacOS X 10.3 NFS client.
