Thanks for the answer.
For the default redundancy rule and pool size 3 you need three separate hosts.
I have 24 separate server nodes with with 32 osd in everyone in total 768 osd, my question is why the mds suffer when only 4% of the osd goes down (in the same node). I need to modify the crush map? El 5/5/21 a las 11:55, Robert Sander escribió:

You need to spread your failure zone in the crush map. It looks like the OSD is the failure zone, and not the host. If it woould be the host the failure of any number of OSDs in a single host would not bring PGs down.
