I am planning to connect a dual port nvme ssd which has two namespace to
two different hosts. One of these hosts will reserve a namespace 1 and use
it through SPDK driver. The other namespace will be attached to a the
kernel nvme driver on the second host for a regular filesystem operations.
Do you foresee any issues with this approach?
the 16.2 release added a Ceph RBD block device as a backend for SPDK
applications. I am wondering about the inverse?
As in: having Ceph RBD OSDs use SPDK to use NVMe flash as underlying
There seems to be efforts with Ceph/Bluestore
to allow OSDs use raw block devices as underlying storage (instead of
Filestore, which shuffles everything through a filesystem).
So put differently: is there a Ceph/Bluestore block device
implementation using SPDK?
