More clearly define ….
We have been doing Openstack POC..
we have an Error during trying to extend cinder volume in cDOT iSCSI FlexVol. ..( ubuntu 12.04 KVM .. Havana version .. cDOT 8.2P3, flexclone enabled, iscsi FlexVol 3TB , available size 2.9TB )
Cinder volume in cDOT NFS FlexVol was OK . Also manual LUN extend was OK in FAS.
It is very critical issue and I can’t find any same cases in google.
I think that it is maybe our Openstack iSCSI Driver bug. ( I also tested it with devstack in our LAB and got a same problem.. )
Please help..

Dear Andrew..
Your response is very clear and I will follow you.
I uploaded another issue in openstack communities…
“cinder extend error with iscsi”
I think that it is maybe our Openstack iSCSI Driver bug. ( I also tested it with devstack in our LAB and got a same problem.. )
