I have firsthand experfience migrating multiple clusters from Ubuntu to RHEL, preserving the OSDs along the way, with no loss or problems. It’s not like you’re talking about OpenVMS ;)

Hi,

Is there anybody running a cluster with different os? Due to the centos 8 change I might try to add ubuntu osd nodes to centos cluster and decommission the centos slowly but I'm not sure this is possible or not.

Thank you
