Hi, I am getting messages like the following from my Ceph systems. Normally this would indicate issues with Drives. But when I restart my system, different and randomly a couple OSDs again start spitting out the same message. SO definitely it's not the same drives every time.
Any ideas on how to debug this. I don't see any drive related issues in dmesg log either.
