Hi Konstantin,
sounds easy;-) If i apply the new rule to the existing pools there won't be any osds to satisfy the requirements of the rule - because the osds are not in the new root yet.
Isn't that a problem ?
Thank you
Your IO will stall.
You need fast move osds to new root. Make list of commands `ceph osd
crush move <osd.n> host=<host-n>` and paste it after apply crush rule.
