Hi,
I have an octopus cluster on the latest octopus version with mgr/mon/rgw/osds on centos 8. Is it safe to add an ubuntu osd host with the same octopus version?
Thank you
Well, the ceph source bits surely remain the same. The binary bits could be different due to better compiler support on the newer OS version. So assuming the new ceph is deployed on the same hardware platform things should be stable. Also, assuming that relevant OS tunables and ceph features and config options have been configured to match the older deployment, the new ceph deployment should just work fine and as expected. Saying all this, I'd still recommend to test out the move one node at a time rather than executing a bulk move. Making a list of types of devices and checking driver support on the new OS would also be a prudent thing to do.
