Fwd: [ceph-users] [IMPORTANT NOTICE] Potential data corruption in Pacific

[Eneko Lacunza]

Thanks Aaron!

I suggest to change "RocksDB resharding broken before 16.2.6" in known 
issues to "RocksDB resharding broken up to 16.2.6" for a more clear heading.

Otherwise I think your change is good.

Cheers
