It's not that simple, you will have to do a lot of edit in the CRUSH map if you want to keep one node in a 3 node cluster as hot backup. IMHO it's not recommended at all to go for such an option. Ceph distributes the data over all the PGs in a pool. If you want redundancy offsite you can have two separated clusters and replicate them with each other. I hope that I made it clear :) _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
