Hi everyone, we are using GPFS 4.1.0.8 with 4 servers and 850 clients. Our GPFS setup is fairly new, we are still in the testing phase. A few days ago, we had some problems in the cluster which seemed to have started with deadlocks on a small number of nodes. To be better prepared for this scenario, I would like to install a callback for Event deadlockDetected. But this is a local event and the callback is executed on the client nodes, from which I cannot even send an email.
Is it possible using mm-commands to instead delegate the callback to the servers (Nodeclass nsdNodes)? I guess it would be possible to use a callback of the form "ssh nsd0 /root/bin/deadlock-callback.sh", but then it is contingent upon server nsd0 being available. The mm-command style "-N nsdNodes" would more reliable in my opinion, because it would be run on all servers. On the servers, I can then check to actually only execute the script on the cluster manager.
