Description Nick Strugnell 2016-03-03 04:53:43 EST
This is an RFE to provide support for generic shared disks such as multi-initiator SCSI disks, and virtual shared disks provided by VMware, libvirt and RHEV.

Currently, the Fiberchannel backend is the only way of providing shared SCSI disk capability, however it is not usable with other kinds of generic shared disks as it executes specific tests in k8s.io/kubernetes/pkg/volume/fc/fc_util.go to check that a real FC disk underlies the PV.

As FC disks are simply a special case of shared disk, it would seem that a generic shared disk driver would be simple to implement, simply by stripping out the FC-specific checks in the existing FC driver.

A trello feature card has been created for this https://trello.com/c/AxRegvYQ/271-provide-support-for-generic-shared-disks

This bug has been identified as a dated (created more than 3 months ago) bug. 
This bug has been triaged (has a trello card linked to it), or reviewed by Engineering/PM and has been put into the product backlog, 
however this bug has not been slated for a currently planned release (3.9, 3.10 or 3.11), which cover our releases for the rest of the calendar year. 

As a result of this bugs age, state on the current roadmap and PM Score (being below 70), this bug is being Closed - Differed, 
as it is currently not part of the products immediate priorities.
