Re: [ceph-users] Working ISCSI target guide
hi. there may be 2 ways. but cephfs is not product-ready. 1. you can use a file stored in cephfs as a target. 2.there is a rbd.ko which map a rbd device as a block device, which you can assign to target. i have not tested yet. good luck At 2014-07-15 09:18:53, "Drew Weaver" wrote: One other question, if you are going to be using Ceph as a storage system for KVM virtual machines does it even matter if you use ISCSI or not?

Re: [ceph-users] Working ISCSI target guide
Drew, I would not use iscsi with ivm. instead, I would use built in rbd support. However, you would use something like nfs/iscsi if you were to connect other hypervisors to ceph backend.

Re: [ceph-users] Working ISCSI target guide
One other question, if you are going to be using Ceph as a storage system for KVM virtual machines does it even matter if you use ISCSI or not? Meaning that if you are just going to use LVM and have several hypervisors sharing that same VG then using ISCSI isn't really a requirement unless you are using a Hypervisor like ESXi which only works with ISCSI/NFS correct?
