NFS locking failed

[vanamala]

I'm using UNFS3 for my customised NFS based PFS filesystem. From the application I'm issuing fcntl() call, it returns with '-1'. lockd and statd are running on my client as well as server nodes. Also the underlying filesystem is a Parallel filesystem which is mounted as NFS filesystem on my local node. 'mount -V nfs local-node:/pfs /mnt/pfs'.

in application I've opened a file using open("/mnt/pfs/test-lock",..) call and i'm trying to lock using fcntl(fd,F_SETLK,&fl). It returns -1...

can anyone help me? I'm not very clear with working of lockd and statd and their interaction with nfsd(is any)... please throw some light on this topic...

thanks in advance!

Can you print the value of errno?
