- osd_out_time
- placement_levels
etcd_mon_ttl
- Type: seconds
- Default: 30
- Minimum: 10
Monitor etcd lease refresh interval in seconds
etcd_mon_timeout
- Type: milliseconds
- Default: 1000
etcd request timeout used by monitor
etcd_mon_retries
- Type: integer
- Default: 5
Maximum number of attempts for one monitor etcd request
mon_change_timeout
- Type: milliseconds
- Default: 1000
- Minimum: 100
Optimistic retry interval for monitor etcd modification requests
mon_stats_timeout
- Type: milliseconds
- Default: 1000
- Minimum: 100
Interval for monitor to wait before updating aggregated statistics in etcd after receiving OSD statistics updates
osd_out_time
- Type: seconds
- Default: 600
Time after which a failed OSD is removed from the data distribution. I.e. time which the monitor waits before attempting to restore data redundancy using other OSDs.
placement_levels
- Type: json
- Default:
{"host":100,"osd":101}
Levels for the placement tree. You can define arbitrary tree levels by defining them in this parameter. The configuration parameter value should contain a JSON object with level names as keys and integer priorities as values. Smaller priority means higher level in tree. For example, "datacenter" should have smaller priority than "osd". "host" and "osd" levels are always predefined and can't be removed. If one of them is not present in the configuration, then it is defined with the default priority (100 for "host", 101 for "osd").
