Hi ,
I 'm in the process of upgrading my ceph cluster from Firefly to Hammer.
The ceph cluster has 12 OSD spread across 4 nodes.
Mons have been upgraded to hammer, since I have created pools with value
512 and 256 , so am bit confused with the warning message.

Since it is a warning .. can I upgrade the OSDs without destroying the data.
or
Should I roll back.
Thanks in advance
