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
