I don't think scrubs can cause this. Do you have autoscaler enabled? Zitat von Lars Köppel <lars.koeppel@xxxxxxxxxx>:
Hi, thank you for your response. I don't think this thread covers my problem, because the OSDs for the metadata pool fill up at different rates. So I would think this is no direct problem with the journal. Because we had earlier problems with the journal I changed some settings(see below). I already restarted all MDS multiple times but no change here. The health warnings regarding cache pressure resolve normally after a short period of time, when the heavy load on the client ends. Sometimes it stays a bit longer because an rsync is running and copying data on the cluster(rsync is not good at releasing the caps). Could it be a problem if scrubs run most of the time in the background? Can this block any other tasks or generate new data itself?

You don't have multi-active MDS enabled, but maybe it's still some journal trimming, or maybe misbehaving clients? In your first post there were health warnings regarding cache pressure and cache size. Are those resolved?
