Re: [rdo-users] [rdo-dev] Cinder NFS backend issue

Hi Tzach, Thank you very much for verifying and reporting the bug. As I moved on to deploy with Ceph, the Cinder volume service is still unavailable. Perhaps the issue is more than just with using NFS? With Ceph, all other pools for Nova (vms) and Glance (images) are working fine; only the Cinder (volumes) has problems. [heat-admin@overcloud-controller-2 ~]$ ceph status cluster: id: 7900258e-cb68-11e8-b7cf-002590a2d123 health: HEALTH_WARN application not enabled on 1 pool(s) services: mon: 3 daemons, quorum overcloud-controller-2,overcloud-controller-0,overcloud-controller-1 mgr: overcloud-controller-2(active), standbys: overcloud-controller-0, overcloud-controller-1 osd: 6 osds: 6 up, 6 in data: pools: 4 pools, 240 pgs objects: 8 objects, 12.1MiB usage: 687MiB used, 10.9TiB / 10.9TiB avail pgs: 240 active+clean My testing environment is like following: 3 controller nodes 3 ceph storage nodes (non-collocated, 1 SSD for journal + 2 HDDs for OSD on each node) 2 compute nodes The deployment is to test an HA cluster (both controller HA and instance HA) with DVR. The cold and live migration would work only after I address this issue [1]. Other than that, the Cinder volume is the only major issue for now.
