I have a cluster with P420 RAID controllers, and very bad performance with SSD.
I know I can configure the controller in HBA mode, but then I will lose the system RAID1.
I would like to switch to HBA mode, reinstall the system in ZFS raid1 and then move the configuration from the old installation so that the node reconnects to the cluster as if nothing happened.
What do I backup from the old installation to achieve this?
Actually there is no Ceph.
Thanks
