[ceph-users] ceph 12.2.9 release

Thanks for the extra info, but I find the question more nuanced than that.

For example in my case I ended up with 12.2.9 on my last handful of 
newly-installed servers (and this is simply using yum rather than 
explicitly ceph-deploy).

We are replacing hardware nodes so the cluster is actively backfilling 
across nodes, which fulfills Greg's criterion of "(the bug) only 
triggers when PGs are not active+clean". Fortunately we are mostly 
backfilling from older to newer minor versions (12.2.8 to 12.2.9), so 
the problem may not manifest itself, but I'm not going to be in a 
position to have all pgs active+clean until the backfills are complete. 
Perhaps at that point it might be safe to upgrade the remaining osds to 
the same 12.2.9? The advice to also not upgrade to 12.9.10 is a bit 
disturbing since it sounds like the feature revert might make it 
incompatible with what we have.
