It's hard to say now. I changed one-by-one my 6 OSDs from btrfs to xfs. During the repair process I added 2 more OSDs. Changed crush map from root-host-osd to root-chasis-host-osd structure... There was SSD cache tiering set, when first inconsistency showed up. Then I removed tiering to confirm than it was not the reason of inconsistencies.
Once there was hardware problem with one node - PCI slot issue. I shut down that node and exchanged motherboard to the same model.
I'm running CentOS Linux release 7.1.1503 (Core) with 3.10.0-229.7.2.el7.x86_64 kernel.

Hi!
When inconsistent PGs starting to appear? Maybe after some event?
Hang, node reboot or after reconfiguration or changing parameters?
Can you say, what triggers such behaviour? And, BTW, what system/kernel
you use?
