hi Caspar, ty for the reply. ive updatet all SSDs to actual firmware. Still having the same error. the strange thing is that this issue switches from node to node and from osd to osd. HEALTH_WARN 4 slow requests are blocked > 32 sec REQUEST_SLOW 4 slow requests are blocked > 32 sec 1 ops are blocked > 1048.58 sec 3 ops are blocked > 262.144 sec osds 20,21 have blocked requests > 262.144 sec osd.12 has blocked requests > 1048.58 sec also there is no symptom that gives me any idea what could be the problem.
