We want to use gexec to be able to execute a command from any cluster node and have it run on all of the cluster nodes.
When we do this on node 1 everything works as expected: On host unfiwcl1 -- unfiwcl1:/# echo $GEXEC_SVRS unfiwcl1 unfiwcl2 unfiwcl3 unfiwcl4 unfiwcl1:/# gexec -n 0 hostname 1 unfiwcl2 0 unfiwcl1 2 unfiwcl3 3 unfiwcl4 However, when I run the same command on node 3 it doesn't work the same way: On host unfiwcl3 -- unfiwcl3:/# echo $GEXEC_SVRS unfiwcl1 unfiwcl2 unfiwcl3 unfiwcl4 unfiwcl3:/# gexec -n 0 hostname 1 unfiwcl2 0 unfiwcl1 <-- Gexec node 0 is cluster node "1" 3 unfiwcl4 2 unfiwcl1 <-- Gexec node 2 _should_ be "3" (the localhost) Here's an example after re-ordering the environment variable (placing localhost first) showing that it works as expected: On host unfiwcl3 -- unfiwcl3:/# export GEXEC_SVRS="unfiwcl3 unfiwcl4 unfiwcl1 unfiwcl2" unfiwcl3:/# echo $GEXEC_SVRS unfiwcl3 unfiwcl4 unfiwcl1 unfiwcl2 unfiwcl3:/# gexec -n 0 hostname 1 unfiwcl4 0 unfiwcl3 2 unfiwcl1 3 unfiwcl2 Must the localhost always be defined first? --Karl
