How to minimize IO starvations while Bluestore try to delete WAL files

[I Gede Iswara Darmawan <iswaradrmwn@xxxxxxxxx>]

Hello,

Recently I have an issue when Bluestore try to delete WAL files (indicated from osd log), the IO of the disk (HDD - Spinning) will reached 100% and will introduced slow request to the cluster. 

Is there any way to throttle this operation down or completely disable it? 

Thanks

Regards,
