Thank you Frank. My focus is actually performance tuning. After your mail, I started to investigate client-side. I think the kernel tunings work great now. After the tunings I didn't get any warning again. Now I will continue with performance tunings. I decided to distribute subvolumes across multiple pools instead of multi-active-mds. With this method I will have multiple MDS and [1x cephfs clients for each pool / Host] To hide subvolume uuids, I'm using "mount --bind kernel links" and I wonder is it able to create performance issues on cephfs clients?
