gansonolwenn: hello! =)13:51
gansonolwenn: the netapp nfs driver creates several files that are used as volumes within a single flexvol in the backend13:52
gansonolwenn: in which property are you seeing the multiple volumes sharing the same ID?13:52
openstackgerritMargarita Shakhova proposed openstack/cinder master: Storwize: get list of all volumes for ensure_export.  https://review.openstack.org/54648913:55
smajl@smcginnis: thx13:56
nolwenn@ganso more precisely we have several nfs shares and for example for a volume, we find the image volume-id on different shares. with different virtual sizes13:57

gansonolwenn: sorry I am bit confused by the terminology. By several nfs shares you mean you have several Flexvols in the backend, which are being exported as NFS shares with their unique junction paths, correct? When you say a "volume", are you referring to a volume in cinder? where do you see the image volume-id on different shares? is this a property in Cinder/Glance, are you looking in the /mnt folder used by Cinder, or14:02
gansoare you looking at the backend?14:02

eharneyif you have an NFS server that only allows a particular user, you may be able to configure some mount options and id mapping on the client to map the cinder user to that user, but i'm not sure17:40
