Hello, everyone!
I have a few questions related to the CephFS part of Ceph:
In order to understand better my questions, my use-case would be the following:- is it production ready?
- can multiple CephFS be created on the same cluster? The CephFS creation page describes how to create a CephFS using (at least) two pools, but the mounting page does not refer to any pool, when mounting the FS;
- besides the pool quota setting, are there any means by which a CephFS can have a quota defined? I have found this document, which is from the Firefly release (and it seems only a draft), but no other references on the matter.
- this page refers to 'mounting only a part of the namespace' -- what is the namespace referred in the page?
- can a CephFS be mounted simultaneously from multiple clients?
- what would be the recommended way of creating system users on a CephFS, if a quota is needed for each user? create a pool for each user? or?
- create a cluster from multiple OSDs (at least 20);
- create 4 pools on it - p1-4;
- create a CephFS from pools p1 and p2 and mount it in /opt/fs1;
- create a CephFS from pools p3 and p4 and mount it in /opt/fs2;
- create some quota defined folders for user's home directories, in /opt/fs1 and /opt/fs2;
Thank you very much!
Regards,Bogdan
