How to reduce HDD OSD flapping due to rocksdb compacting event?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Ceph Users,

Is there a way around to minimize rocksdb compacting event so that it won't use all the spinning disk IO utilization and avoid it being marked as down due to fail to send heartbeat to others?

Right now we have frequent high IO disk utilization for every 20-25 minutes where the rocksdb reaches level 4 with 67GB data to compact.


Kind regards,

Charles Alva
