If an Fsched cluster uses Ubuntu 22.04, configure the cluster as follows:
SSH login restriction depends on cgroups. Therefore, Fsched clusters using Ubuntu 22.04 cannot use the SSH login restriction feature.
After the upgrade, Fsched clusters will be reconfigured, and the original job tracking configuration will be changed to cgroup mode.
In some versions, the default job tracking feature for Fsched clusters is switched to cgroup mode. However, Ubuntu 22.04 does not support this cgroup mode. As a result, Fsched clusters using this operating system may encounter abnormal cluster configuration. To ensure that the Fsched cluster can be configured properly, after the cluster is created successfully, configure the following custom parameters at the cluster level:
Depending on the application, task usage tracking may be incomplete:
JobAcctGatherType = jobacct_gather/linux
ProctrackType = proctrack/pgid
