There's probably a bug somewhere between the Linux Kernel NFS service and the ZFS code. I suspect that it'll be up to the ZFS on Linux folks to debug it, since the Linux Kernel developers will probably be more concerned with making supported filesystems work with NFS. I know I used to have problems back in the RHEL4 days with exporting XFS filesystems via NFS on Linux, and we had to migrate back to ext3. XFS support is much better now, but it's also something that both upstream (RHEL) and the kernel developers maintain. -- Jonathan Billings <billings at negate.org>
