Bonus Episode: Importing an Existing Ceph Cluster into croit

In this bonus episode, James Godfrey walks you through the process of importing an existing Ceph cluster into croit—demonstrating a zero-downtime, supported transition path for production workloads. -Use croit to import clusters deployed with cephadm, Ceph-Ansible, ceph-deploy, or other methods -Deploy the croit manager and set up PXE boot networking for the import -Use the Ceph admin key and monitor IPs to securely connect to the existing cluster -Reboot and PXE-boot each node into the croit image one by one -Zero downtime is possible if your original cluster is properly sized with redundant services (e.g., active/standby MDS) -Recreate services (MON, MDS, RGW) in the croit GUI with preconfigured disk and network settings -Manage monitor map cleanup and re-add each node with a clean state -Wipe old OS disks and reassign them for MONs or other roles as needed -Configure NICs, bonds, and failover settings as part of the transition -Validate cluster health at every step—ensuring your OSDs, MONs, and MDSs are fully functional -Import works across topologies, storage backends, and cluster sizes—with croit support required to ensure safe handling of your data croit’s import workflow provides a supported, seamless path from existing Ceph clusters into a modern, easy-to-manage platform—with no compromise on resilience, visibility, or control.
