Description Steve Dickson 2004-12-14 13:38:27 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.3)

Description of problem:
when trying to mount a nfs4 filesystem on another remote fedora core 3
(FC3), i got the following error repeated on the client syslog :
Dec 10 15:46:27 filer2 kernel: decode_getfattr: xdr error 10008!
Dec 10 15:46:43 filer2 kernel: decode_getfattr: xdr error 10008!

... while the mount command seems to be "freezed" (but interruptible
by ^C). So any of my attempts to mount with nfs4 failed.

Here is the config on both nodes:
kernel 2.6.9 compiled from tarballs from kernel.org, all nfs option
compiled-in the kernel itself.
Fedora Core 3 with unmodified tools (FC3 seems to natively support nfs4)
both portmaps on client and server listen only to localhost
(vanemery's doc allow access to portmap only to localhost, so i think
it does the same)

Server: nfs export of a XFS partition
$ cat /etc/exports

The mount command on the client was:
mount -t nfs4 -o ro,intr /home/

i used the AUTH_SYS method described step by step on the vanemery tutorial
except the "acl" mount option because xfs doesn't accept it. (i think
xfs supports ACLs natively)

anyone has an idea about the "xdr error 10008" error ?

Thanks in advance,

Proposed Patch

An if statement was removed that may been the
reason an event was not being register, which
in turned cause idmapper to ignore requests
from the kernel.

Comment 2 Steve Dickson 2005-02-14 18:26:24 UTC
Fixed in nfs-utils-1.0.6-50.i386.rpm
