Hi, I am learning NFS (and pNFS) and not much familiar with its implementation in Linux kernel. I have a question on the LAYOUTGET operation. I have a pNFS server setup which fakes most of the pNFS operations. The "layout_get" implementation simply returns "-ENOENT". I am not sure how this should be treated on the pNFS client side. In my experiment, I am mounting the pNFS server and trying to read a file (using "cat"). On wireshark trace (attached with the mail), I could see that LAYOUTGET fails with NFS4ERR_BADLAYOUT error, but afterwards I see the READ request from client and it is handled gracefully (and I can see the contents of the file). Is this appropriate behavior? I am using RHEL6.1 (with pNFS patch for kernel 2.6.32 applied) on server, and client is RHEL6.1 stock kernel. I am sorry if this is not the appropriate forum for such kind of questions, and pardon my ignorance/lack of knowledge in the domain. Thanks, Vishal
