Description
when I set db_path into ssd(12 osds db in sdy) ,I found the Speed of reading is too high when the compactions is running,the sdo and sdr (have no ssd to store db data) also to hight when the compactions is running.
!!
My configuration is as follows:
bluestore_block_db_size = 10737418240
I use ceph-disk to create osd:
ceph-disk prepare /dev/sdo --block.db /dev/sdy
My question is, why do I read it at such a high speed? How can I make it smooth?
