Currently in a test-lab / sandbox environment, I am running the latest version of Ceph Tentacle release (v20.2.0) in a virtualized environment. If I wanted to downgrade back to Squid (v19.2.3), what steps would I go about doing that? I am not worried about any of the data in the environment as its strictly for testing purposes, patch assessment for OS and Ceph, etc. ubuntu@ceph-mon1:~$ sudo ceph versions { "mon": { "ceph version 20.2.0 (69f84cc2651aa259a15bc192ddaabd3baba07489) tentacle (stable - RelWithDebInfo)": 2 }, "mgr": { "ceph version 20.2.0 (69f84cc2651aa259a15bc192ddaabd3baba07489) tentacle (stable - RelWithDebInfo)": 2 }, "osd": { "ceph version 20.2.0 (69f84cc2651aa259a15bc192ddaabd3baba07489) tentacle (stable - RelWithDebInfo)": 3 }, "mds": { "ceph version 20.2.0 (69f84cc2651aa259a15bc192ddaabd3baba07489) tentacle (stable - RelWithDebInfo)": 1 }, "rgw": { "ceph version 20.2.0 (69f84cc2651aa259a15bc192ddaabd3baba07489) tentacle (stable - RelWithDebInfo)": 2 }, "overall": { "ceph version 20.2.0 (69f84cc2651aa259a15bc192ddaabd3baba07489) tentacle (stable - RelWithDebInfo)": 10 } } Environment is running Ubuntu v22.04 and Ceph was deployed via cephadm. -- Michael This message and its attachments are from Data Dimensions and are intended only for the use of the individual or entity to which it is addressed, and may contain information that is privileged, confidential, and exempt from disclosure under applicable law.
