Ok, so if a journal failure is lethal, ceph automatically remove the affected OSD and start rebalance, right ? > Additionally your cluster should (NEEDS to) be designed to handle the > loss of a journal SSD and its associated OSDs, since that is less than a > whole node, or a whole rack (whatever your failure domain may be). What do you suggest about this? In the (small) cluster i'm trying to plan, I would like to be protected on every component up to the whole rack. I have 2 different racks for the storage, so data should be spread across both and still keep the single OSD/Journal failure as failure domain Yes, reading docs should answer to many questions (and I'm reading), but having a mailing list where expert people reply is much better. _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
