Hello Vinícius Ferrão, Please make sure chronyd is installed on the node you intend to use it. And redo the xCAT ntp setup procedure on that node.
For the xCAT management node, do the following, 1. Make sure chronyd is installed on xCAT management node. 2. Run `makentp’ For xCAT compute nodes, do the following, 1. Make sure chronyd is installed on xCAT compute nodes you intend to use chronyd 2. Run `xdsh compute_nodes setupntp’, where compute_nodes is your node range.
