Hi, Deployed Tripleo Liberty stable on baremetal, but NetApp NFS Cinder backend is not working. It is auto-mounting no problem, and I can write to it with sudo, but the 'tripleo_netapp' backend is enabled with state 'down' as it cannot write to the mount point. cinder service-list | grep tripleo_netapp | cinder-volume | hostgroup@tripleo_netapp | nova | enabled | down [heat-admin@overcloud-controller-0 ~]$ mount | grep cinder [ip addr]:/[mount] on /var/lib/cinder/mnt/3fb6f6744c383eacbe46593911aa4b0f type nfs4 (rw,relatime,vers=4.1,rsize=65536,wsize=65536,namlen=255,hard,proto=tcp,port=0,timeo=600,retrans=2,sec=sys,clientaddr=[ip addr],local_lock=none,addr=[ip addr]) I can write to it - [heat-admin@overcloud-controller-0 ~]$ sudo touch /var/lib/cinder/mnt/3fb6f6744c383eacbe46593911aa4b0f/test [heat-admin@overcloud-controller-0 ~]$ But Cinder cannot - /var/log/cinder/volume.log:2016-04-29 09:43:49.870 56696 ERROR cinder.volume.drivers.remotefs [req-99928048-2446-4967-99ba-0e85c2ba5712 - - - - -] Failed to created Cinder secure environment indicator file: [Errno 13] Permission denied: '/var/lib/cinder/mnt/3fb6f6744c383eacbe46593911aa4b0f/.cinderSecureEnvIndicator' So this look like an issue with the user that Cinder is using to write to the export (cinder?)? I have tried setting this option in cinder.conf, but it makes no difference nas_secure_file_operations = False "Allow network-attached storage systems to operate in a secure environment where root level access is not permitted. If set to False, access is as the root user and insecure. If set to True, access is not as root. If set to auto, a check is done to determine if this is a new installation: True is used if so, otherwise False. Default is auto" Any help appreciated Thanks Charles -- Charles Short Cloud Engineer Virtualization and Cloud Team European Bioinformatics Institute (EMBL-EBI) Tel: +44 (0)1223 494205
