Hi, I bet I did read it somewhere already, but can’t remember where…. Our ceph 10.2. cluster is fin and healthy and I have a couple of rbds exported to some fileserver and a nfs server. The upgrade to V 12.2 documentation is clear regarding upgrading/restarting all MONs first, after that, the OSDs. My question is: How to proceed with the serves which map the rbds? Upgrading these after the ceph MONs/OSDs? May I notice some interruption to the RBDs resp. the SMB and NFS Services? The NFS hosts some VMs for Xen … Thanks for feedback dun comments . Regards .
