Just reaching out for experiences on Openstack deployments with Netapp NFS.  Are you using the default v4 or have switched the mount options to v3? We have a pretty good base of ISCSI, but based on performance and manageability are considering making the jump.

Speaking of NFSv4, outside of openstack has anyone made any large deployments? Is it as solid as v3? using uid/gid, is anyone using sec=krb5?

Regards,

Douglas
