I've removed two key's:
#ceph config-key rm mgr/cephadm/host.hvs004.devices.0
#ceph config-key rm mgr/telemetry/host-id/hvs004
Now I only have 'history' key's.
#ceph config-key ls | grep hvs004 | head gives me:
"config-history/1027/+osd/host:hvs004/osd_memory_target",
"config-history/1027/-osd/host:hvs004/osd_memory_target",
"config-history/1028/+osd/host:hvs004/osd_memory_target",
"config-history/1028/-osd/host:hvs004/osd_memory_target",
"config-history/1037/+mgr.hvs004.fspaok/container_image",
"config-history/1043/-mgr.hvs004.fspaok/container_image",
"config-history/1054/+client.crash.hvs004/container_image",
"config-history/1059/-client.crash.hvs004/container_image",
"config-history/1274/+mgr.hvs004.fspaok/container_image",
"config-history/1279/-mgr.hvs004.fspaok/container_image",
#ceph config-key ls | grep -v history | grep hvs004 doesn't list any keys anymore
I assume I should remove these 'history' key's to?
Note => for now the removed host is still in the warning...
#ceph health detail
HEALTH_WARN 1 host is in maintenance mode
[WRN] HOST_IN_MAINTENANCE: 1 host is in maintenance mode
hvs004 is in maintenance
