Public bug reported:
I encountered an kernel oops running 3.11.0-7-generic #13-Ubuntu SMP Tue
Sep 10 20:55:38 UTC 2013 x86_64 GNU/Linux under Debian Squeeze 6.0.7
amd64 on an Opteron barebone.
This server is an NFS client using cachefilesd.
The NFS server is Debian Squeeze 6.0.7 amd64 running 3.2.0-0.bpo.4-amd64
#1 SMP Debian 3.2.46-1~bpo60+1 x86_64 GNU/Linux and nfs-kernel-server on
an Opteron barebone.
No kerberos is in use.
To get things up and running for 700+ user ids, i configured the
following on the client, using trial and error, to have the correct user
ids on the NFS mount:
echo N > /sys/module/nfs/parameters/nfs4_disable_idmapping
kernel.keys.root_maxbytes = 100000
kernel.keys.root_maxkeys = 1000
kernel.keys.maxbytes = 100000
kernel.keys.maxkeys = 1000
I was capturing the trace via an SSH session using tail -f so some
information might be missing :-/ (attached)
Thanks,
Raoul
