Unify and standardize inventory_hostname This was causing some confusing conflicts, so create a new fact called "this_node" which is inventory_hostname.split('.')[0], i.e. the short name, and use that everywhere instead of an FQDN or true inventory hostname. 2023-09-01 15:42:28 -04:00			`# Set this_node fact`
Limit database tasks to coordinators only Non-coordinators don't need these configurations as they shouldn't run there. 2023-09-01 15:42:21 -04:00			`- set_fact:`

Add Ceph OSD cpuset tuning options Allows an administrator to set CPU pinning with the cpuset tool for Ceph OSDs, in situations where CPU contention with VMs or other system tasks may be negatively affecting OSD performance.

Move IP removal and restart after install 2023-09-01 15:42:20 -04:00
Add updated tuning configuration Uses a much nicer CPU tuning configuration, leveraging systemd's AllowedCPUs and CPUAffinity options within a set of slices (some default, some custom). Configuration is also greatly simplified versus the previous implementation, simply asking for a number of CPUS for both the system and OSDs, and calculating everything else that is required. Also switches (back) to the v2 unified cgroup hierarchy by default as required by the systemd AllowedCPUs directive. 2023-09-01 15:42:29 -04:00			`# Install CPU tuning`
