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

[Ken Dreyer (Red Hat)]

Sure. Also note that I think these utilities rely on features in kernel
4.9 (also backported to RHEL 7.3's upcoming kernel-3.10.0-514.el7 or
later), so it probably won't work on Ubuntu 14.04 and 16.04's standard
kernels. In terms of HWE kernels for those, it looks like only 16.04.3
or 16.04.4 will have HWE kernel 4.9 or newer.

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.
