[rdo-dev] Cinder NFS backend issue

Hi everyone, I have an issue with using TripleO (Queens) to setup an NFS backend for Cinder. My storage.yaml is as follows: parameter_defaults: CinderEnableIscsiBackend: false CinderEnableRbdBackend: false CinderEnableNfsBackend: true NovaEnableRbdBackend: false GlanceBackend: 'file' CinderNfsMountOptions: 'rw,sync' CinderNfsServers: '192.168.24.1:/export/cinder' GlanceNfsEnabled: true GlanceNfsShare: '192.168.24.1:/export/glance' GlanceNfsOptions: 'rw,sync,context=system_u:object_r:glance_var_lib_t:s0' NovaNfsEnabled: true NovaNfsShare: '192.168.24.1:/export/nova' NovaNfsOptions: 'rw,sync,context=system_u:object_r:nfs_t:s0' I used the undercloud node as an NFS server for testing purposes. Iptables is set accordingly. The /etc/exportfs on the NFS server is as follows: /export/nova 192.168.24.0/24(rw,no_root_squash) /export/glance 192.168.24.0/24(rw,no_root_squash) /export/cinder 192.168.24.0/24(rw,no_root_squash) All three folders are set to chmod 777. Nova and Glance work as expected. Only Cinder remains problematic. I can try to upload volumes from overcloud, but nothing would show up in the cinder folder. Also Horizon gives errors like unable to retrieve volume and volume snapshots. Did I miss something here? I do plan to use Ceph later, but I wish to use NFS for now to test migration and failover. Any helps would be appreciated. Thank you! Best regards, Cody
