Hello, Nick! Thank you for your reply! I have tested both with setting the replicas number to 2 and 3, by setting the 'osd pool default size = (2|3)' in the .conf file. Either I'm doing something incorrectly, or they seem to produce the same result.
Can you give any troubleshooting advice? I have purged and re-created the cluster several times, but the result is the same. Thank you for your help!
