Today we use ceph jewel with:
osd disk thread ioprio class=idle
osd disk thread ioprio priority=7
and "nodeep-scrub" flag is set.
We want to change scheduler from CFQ to deadline, so these options will lose effect.
I've tried to find out what operations are performed in "disk thread". What I found is that only scrubbing and snap-trimming operations are performed in "disk thread".
Do these options affect recovery operations?
Are there any other operations in "disk thread", except scrubbing and snap-trimming?
