List-Unsubscribe: , List-Archive: Hi all, I'm experiencing some problems with a cluster setup. The cluster is set up in a way that you have a frontend machine configured as a masquerading gateway and all the compute nodes behind it on a private network (i.e the frontend has two network interfaces). User home directories and also other data directories which should be available to the cluster (i.e statically mounted in the same location on both frontend and nodes) are located on external NFS servers (IRIX and Linux servers). This seems to work fine when the cluster is in use, but if the cluster is idle for some time (e.g over night), the NFS directories has become unavailable and trying to reboot the frontend results in a complete hang when it tries to unmount the NFS directories (it hangs in a fuser command). The frontend and all the nodes are running RedHat 7.2, but with a stock 2.4.18 kernel (plus Trond's seekdir patch, thanks for the help BTW). Ideas anyone ?
