Hi Hauke, 1. Yes you can use different client version in general. Its not recommanded and of course you might run in the situation that the server and client does not support the same features. So you should check that. Just like in NFS/SMB/any other, its usually a bad idea to have a newer client access an older server. Also, jewel, because of major changes inside cephfs, might have a special position where you are forced to use the jewel clients together with the jewel servers. ---- 2. Thats your personal flavour / choice if you are using SMB/NFS. But you should consider, that both are no cluster system and generate SPOF automatically. And this way, erasing most coolness of ceph as a technology. To avoid this, you might want to add some underlying cluster environment like corosync or what ever. And then again, is the question, if you want to run ceph server software, cluster environment software and nfs/smb software all on the same host. Murphy has a lot of choices to make this compilation more fun for the admin. ---- 3. Its highly recommanded to access cephfs with cephfs and not anything else when speed is a matter for you. I have no exerience with constructions you want to build. So i dont know if a newer version of samba or a "vfs Module ceph" ( what ever that is ) will help. But i doubt, that at the end of the day, the construction you try to build will have anything to do with speed. Simply too many layers in between. So you should really check if you can access this all via cephfs from the clients. -- Mit freundlichen Gruessen / Best regards Oliver Dzombic IP-Interactive mailto:info@xxxxxxxxxxxxxxxxx Anschrift: IP Interactive UG ( haftungsbeschraenkt ) Zum Sonnenberg 1-3 63571 Gelnhausen HRB 93402 beim Amtsgericht Hanau Geschäftsführung: Oliver Dzombic Steuer Nr.: 35 236 3622 1 UST ID: DE274086107 Am 16.04.2016 um 08:53 schrieb Hauke Homburg: > > Hello, > > I am installing a Ceph Cluster as File Server with Jewel under Centos 7. > At this Moment it is not in Produktion.
