Occasionally I am seeing the following in our kernel log on a NFS client:

[2321389.137615] NFS: state manager: lease expired failed on NFSv4 server enkf with error 1
The result is that the read of the file in question fails. This occurs for multiple kernel versions on multiple machines. Anyone have an idea how I should start debugging this? How is the clientid calculated/assigned?
It depends on the kernel version. You can look in fs/nfs/nfs4proc.c for the nfs4_proc_setclientid function.
I am still occasionally seeing this error. The last time was with the NFS client and server both running kernel 3.11.6. The message was on the client. Here is the mount info from /proc/mounts:
margaret:/home/margaret/margaret /home/disk/margaret nfs4
rw,relatime,vers=4.0,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,port=0,timeo=600,retrans=2,sec=sys,clientaddr=140.142.113.26,local_lock=none,addr=128.95.89.30
0 0
I am still looking for ideas on how to debug this.
