2.6.24.3 nfs server on xfs keeps producing nfsd: non-standard errno: -117

[Stuart Rowan <strr-debian@decisionsoft.co.uk>]

Hi,

Firstly thanks for the great filesystem and apologies if this ends up being 
NFS rather than XFS being weird! I'm not subscribed so please do keep me CC'd.

I have *millions* of lines of (>200k per minute according to syslog):
nfsd: non-standard errno: -117
being sent out of dmesg

Now errno 117 is
#define EUCLEAN         117     /* Structure needs cleaning */
which seems to be only used from a quick grep by XFS and JFFS and smbfs.


My nfs server export two locations
/home
/home/archive
both of these are XFS partitions, hence my suspicion that the -117 is 
coming from XFS.

xfs_repair -n says the filesystems are clean
xfs_repair has been run multiple times to completion on the filesystems, 
all is fine.

The XFS partitions are lvm volumes as follows
data/home 900G
data/archive 400G
The volume group, data, is sda3
sda3 is a 6 drive 3ware 9550SXU-8LP RAID10 array

The NFS server is currently in use (indeed the message only starts once 
clients connect) and works absolutely fine.

How do I find out what (if anything) is wrong with my filesystem / 
appropriately silence this message?

Many thanks,
Stu.
