What is meaning of Error: state recovery failed on NFSv4 server xx.xx.xx.xx with error 2

[Neil Brown]

Hi,
 I'm after some help interpreting this error message:

 Error: state recovery failed on NFSv4 server xx.xx.xx.xx with error 2

'2' is ENOENT, so it looks like the nfs4_get_setclientid_cred call in 
reclaimer (in fs/nfs/nfs4state.c) returned NULL.
This implies that clp->cl_state_owners is empty.

Is this really a problem that is worthy of an 'Error:' message, or
does it simply signify that no state has been established yet??

(Kernel in question is 2.6.16.20 based, but the code doesn't seem to
have changed much since then).

Thanks,
NeilBrown
