PG increase / data movement fine tuning

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

 



Hi,

I've increased the placement group in my octopus cluster firstly in the index pool and I gave almost 2.5 hours bad performance for the user. I'm planning to increase the data pool also, but first I'd like to know is there any way to make it smoother or not.

At the moment I have these values:

osd_max_backfills = 1
osd_recovery_max_active = 1
osd_recovery_op_priority = 1

But seems like this still generates slow ops.

Should I turn off scrubbing or any other way to make it even smoother?


Some information about the setup:

  *   I have 9 nodes, each of them has 2x nvme drives with 4osd on those and this is where the index pool lives.
  *   Currently has 2048 pg-s for the index pool

Thank you
