Blocking IO when hot tier promotion daemon runs
I've recently enabled an SSD backed 2 TB hot tier on my 150 TB 2 server / 3
bricks per server distributed replicated volume.
I'm seeing IO get blocked across all client FUSE threads for 10 to 15
seconds while the promotion daemon runs. I see the 'glustertierpro' thread
jump to 99% CPU usage on both boxes when these delays occur and they happen
every 25 minutes (my tier-promote-frequency setting).
I suspect this has something to do with the heat database in sqlite, maybe
something is getting locked while it runs the query to determine files to
promote...
