NFS mount point hang on I/O   Hi Folks, New cdot isntall, new NFS vserver. NFS shares can be mounted OK on linnux and solaris clients. I can mkdir and touch files. Copy or move or DD or any I/O operation completly hangs the mount point, the process cannot be Control-C, and kill -9 does not even help

Thanks.I can get unmounted and remounted, but I cannot overcome the issue of copy any files into filesystem, or writing anything to it. Nothing besides mkdir and touch works..Something is wrong with the setup...

Are you sure you are not mounting it over a mgt interface and saturating it? Is your copy a large file? Can you copy a few small files? While it is hanging, can you use nfsiostat to see if there is actually zero traffic or if it is moving slow?
