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 The trace is attached.
