Hi ,
We are validating kraken 11.2.0 with bluestore on 5 node cluster with EC 4+1.
When an OSD is down , the peering is not happening and ceph health status moved to ERR state after few mins. This was working in previous development releases. Any additional configuration required in v11.2.0
Following is our ceph configuration:
mon_osd_down_out_interval = 30
mon_osd_report_timeout = 30
mon_osd_down_out_subtree_limit = host
mon_osd_reporter_subtree_level = host
and the recovery parameters set to default.
[root@ca-cn1 ceph]# ceph osd crush show-tunables
