Tingjie:

 

Thanks for putting this together as it gives a very good summary of the changes in the CEPH mimic version which is expected to merge in the near future into StarlingX.  This list will be a good reference for those who will be running TCs for the new CEPH version.  I have a couple of questions – would you be able to help me:

 

1.       One of the notes indicates “There is a simplified OSD replacement process that is more robust.”

·         Can you explain what these changes are? 

·         Will this result in any changes to the steps an operator takes to replace a CEPH disk?

2.       Another note indicates “Several sleep settings, include osd_recovery_sleep, osd_snap_trim_sleep, and osd_scrub_sleep have been reimplemented to work efficiently.”

·         Can you share the settings used in StarlingX today with CEPH jewel as well as the planned settings that will be used in StarlingX with CEPH mimic.  Will any of these settings change value when CEPH mimic is merged into StarlingX?

3.       One more note indicates “CLI changes”

·         Can you explain which CLIs have changed?
