Add TunedCustomProfile parameter which may contain a string in INI format describing a custom tuned profile. Also provide a new environment file for users of hypercoverged Ceph deployments using the Ceph filestore storage backened. The tuned profile is based on heavy I/O load testing. The provided environment file creates /etc/tuned/ceph-filestore-osd-hci/tuned.conf whose content is the following and sets this tuned profile to be active. [main] summary=ceph-osd Filestore tuned profile include=throughput-performance [sysctl] vm.dirty_ratio = 10 vm.dirty_background_ratio = 3 [sysfs] /sys/kernel/mm/ksm/run=0 Depends-On: Iba17d86bbdd710623ba1ba44b1ea5d4c1b99c541 Change-Id: Iaa1c82cefac5c8f2959fd7aeb57bd6860fd9096a Closes-Bug: #1800232
