Re: [HPDD-discuss] Can't mount to client

I would start by checking out the network layer to make sure that everything is setup and functioning as expected. 1) Make sure all nodes have the correct IP address configured 2) Run "lctl list_nids" on all nodes to make sure that the LNET layer has setup all the interfaces 3) Run "ping $IPADDR" and "lctl ping $IPADDR@tcp0" tests between nodes to check that communication is working You may have already checked those things out, and it may seem like I am pointing out the obvious. But I have seen several lustre problems that ended up being caused by simple problems like an IP address being configured on the wrong interface or a typo in modprobe config file. So the above checks are almost always my starting point whenever I encounter a lustre problem.
