I strongly recommend you to ask for a expierenced Ceph consultant that helps you design and setup your storage cluster.
I known I'm working on (meaning I'm waiting my administration to do «what need to be done)...
It looks like you try to make design decisions that will heavily influence performance of the system.
I'm well aware....
If I say 20-30 it's because I currently have on my classic ZFS/NFS server around 25 «datasets» exported to various server.
The next question is how would the "consumers" access the filesystem: Via NFS or mounted directly. Even with the second option you can separate client access via CephX keys as David already wrote.
The separate client key would be more than enough for us.
Ok. 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 ?
Do you intend to use the Ceph cluster only for archival storage?
Mostly yes.
Hwo large is your second set of Ceph nodes, how many HDDs in each? Do you
Huge ;-) I got 6 ceph server with ... 60 HDD. (I know, I know it's not ideal)
intend to use the SSDs for the OSDs' RocksDB?
RocksDB ? no...
Where do you plan to store the metadata pools for CephFS? They should be
That's exactly the question... My cluster are : 5 server with «small» ssd for service (each got 2 ssd no currently used) 6 server with «huge» HDD for data (each got 2 ssd no currently used) so for my cephfs metadata I can put them on my 5 servers for services (but that's mean the mds running on those 5 servers) or should I use the ssd on the 6 server who hold the OSD for data Thanks.
