Hello,
A couple of weeks agoo we upgraded our Netapp filer to 8.1.1RC1. We have
always had trouble with NFS and state id's. Resulting in hanging clients.
(Client: SLED11 SP2, 3.0.34-0.7-default x86_64)
The "hanging" seems to be caused by the server returning an
NFS4ERR_BAD_STATEID(10025) status for PUTFH;LOCK and PUTFH;WRITE;GETATTR
calls. The client is making several hundreds of these identical (same
filehandle) calls each second.
The problem seems to be triggered by (write) actions on an open file
when the Kerberos ticket has expired (especially for .xsession-errors
and files opened by Firefox or Thunderbird).
When (after some time) a new valid ticket is obtained, the kernel
reports this error:
nfs4_reclaim_open_state: unhandled error -10026. Zeroing state
Is this a client or a server problem (and is there by any chance a fix)?
Robbert
