Hi Craig, Sorry for late response. Somehow missed this mail. All osds are up and running. There were no specific logs related to this activity. And, there are no IOs running right now. Few osds were made in and out ,removed fully and recreated before these pgs coming to this stage. I had tried restarting osds. It didn’t work.

Is it consuming lots of CPU or IO? Is it flapping? Writing any interesting logs? Have you tried restarting it? If that doesn't help, try the other involved osds: 56, 27, 6, 25, 23. I doubt that it will help, but it won't hurt.
