[Bug 1636544] Re: SUSE lrbd support for high availability iSCSI gateway and multipath support of Ceph RBD images

[Ken Dreyer (Red Hat)]

To clarify the list of supported OSes: I am leaning towards retiring
lrbd from Fedora, and we have no plans to ship that tool on RHEL (via
the Red Hat Ceph Storage product).

Instead, we're going to use these projects to manage the userland iSCSI
bits:

https://github.com/pcuzner/ceph-iscsi-ansible
https://github.com/pcuzner/ceph-iscsi-config
https://github.com/pcuzner/ceph-iscsi-tools

We have not put ceph-iscsi-ansible into Fedora yet because there is
still some question regarding whether ceph-iscsi-ansible upstream will
eventually merge with ceph-ansible upstream, but it's in progress.

Title:
  SUSE lrbd support for high availability iSCSI gateway and multipath
  support of Ceph RBD images

Status in ceph package in Ubuntu:
  New

Bug description:
  When will Ubuntu support SUSE lrbd utility to simplify iSCSI
  management of Ceph RBD images?

  I read their article about LIO using Ceph RBD as iSCSI with multiple
  gateway and path support for high availability iSCSI targets. SUSE,
  Fedora24, and RHEL7 already support lrbd, but Ubuntu 16.04.1 and 16.10
  do not.

  It would be great for Ubuntu to have this lrbd utility for exporting
  Ceph RBD over LIO iSCSI with with high availability gateway and
  multipath IO to Linux, Windows, and VMware.
