Hi folks, at this time we recommend pausing OSD upgrades to 15.2.2. There have been a couple reports of OSDs crashing due to rocksdb corruption after upgrading to 15.2.2 [1] [2]. It's safe to upgrade monitors and mgr, but OSDs and everything else should wait. We're investigating and will get a fix out as soon as we can.
