Description Andrew Cathrow 2013-04-26 01:24:15 UTC 
in BZ 892686 we developed a gluster driver for cinder that uses the fuse interface. There is a significant advantage in using the native qemu support that's been added recently upstream and is coming in RHEL 6.5
Comment 1 Eric Harney 2013-06-25 21:14:04 UTC 
*** Bug 978041 has been marked as a duplicate of this bug. ***
Comment 2 Eric Harney 2013-08-14 14:19:32 UTC 
No code changes directly in Cinder.  Nova changes tracked in bug 978503.
Comment 5 Dafna Ron 2013-08-23 10:53:09 UTC 
sanity plan created and sent to programmer for review:

Comment 11 Dafna Ron 2013-12-02 10:29:13 UTC 
Eric, since this was moved on_qa, please explain how we can test this.
Comment 12 Eric Harney 2013-12-02 15:08:04 UTC 
Set qemu_allowed_storage_drivers=gluster on the Nova compute node, attach a volume via GlusterFS, and then look at "virsh domblklist" and you will see that it is using a network disk rather than a path to a file.  ("virsh dumpxml" may provide a more obvious way to see this, the difference in domblklist is easy to overlook.)

Note that this is not working with snapshots yet, need bug 1017288 to get sorted out.
Comment 15 Dafna Ron 2013-12-11 16:31:39 UTC 
see bug 1020979 for configuration
Comment 16 Dafna Ron 2013-12-12 10:54:47 UTC 
since we cannot attach a volume (1020979) I am blocking this FRE.
