Hi, I am using ceph Nautilus cluster with below configuration. 3 node's (Ubuntu 18.04) each has 12 OSD's, and mds, mon and mgr are running in shared mode. The client mounted through ceph kernel client. I was trying to emulate a node failure when a write and read were going on (replica2) pool. I was expecting read and write continue after a small pause due to a Node failure but it halts and never resumes until the failed node is up. I remember I tested the same scenario before in ceph mimic where it continued IO after a small pause. regards Amudhan P
