I got for my ceph cluster two set of servers, first set are for services (mgr,mon,etc.) with ssd and don't currently run any osd (but still have 2 ssd not used), I also got a second set of server with HDD and 2 SSD. The data pool will be on the second set (with HDD). Where should I run the MDS and on which osd ? > > > Il will also need to have ceph S3 storage, same question, should I have a > > designated pool for S3 storage or can/should I use the same > > cephfs_data_replicated/erasure pool ? > > No, S3 needs its own pools. It cannot re-use CephFS pools. Ok thanks.
