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. You
can follow progress on this tracker:
