I want to pool a large number of hard drives over the network to provide a large backup space.
I want also to partition this space and make it available to several machines as a backup space.
I understand ceph can pool the hard drives, but it doesnt support quotas. Should I create several devices inside ceph? or should I expose it via an ftp server?
can someone explain me what is the best way to use ceph?
It seems I should use block devices http://ceph.com/docs/master/rbd/rbd/
I.e.: I should make a block device of the desidered size, then mount it on the VM for backup purpose. Is this right? How do I limit a block device to a given user?
Can I achieve the same with CephFS?
