Hello, We have a new build going up in our DC of Openstack Newton. We wanted to build in a shared storage solution and really liked the simplicity as well as functions of glusterFS. This would allow us to perform live migrations along with Geo replication. The issue we have been having is getting nova-libvirt instances to run on the compute nodes with the glusterfs mount point of /var/lib/nova/instances.
We have added all the required permissions on the volume share : Volume Name: gfsimgstore Type: Replicate Volume ID: 768d161f-78ca-40dd-befc-ddf9de2ccb38 Status: Started Snapshot Count: 0 Number of Bricks: 1 x 2 = 2 Transport-type: tcp Bricks: Brick1: cloud304-node1:/bricks/imgstore1 Brick2: cloud304-node2:/bricks/imgstore1 Options Reconfigured: cluster.data-self-heal-algorithm: full features.shard: on cluster.server-quorum-type: server cluster.quorum-type: auto network.remote-dio: enable cluster.eager-lock: enable performance.stat-prefetch: off performance.io-cache: off performance.read-ahead: off performance.quick-read: off server.allow-insecure: on storage.owner-gid: 162 storage.owner-uid: 162 transport.address-family: inet performance.readdir-ahead: on nfs.disable: on We have modified permissions following what documentation we were able to locate, but we still get errors when we try to create a VM. The errors are a lot but this is the final error that stands out: 2017-01-23 18:29:25.798 12184 ERROR nova.compute.manager [instance: c6634e67-b293-4424-96ec-f0c58b2bf081] libvirtError: Unable to open file: /var/lib/nova/instances/c6634e67-b293-4424-96ec-f0c58b2bf081/console.log: Permission denied 2017-01-23 18:29:25.798 12184 ERROR I am hoping I can find someone running glusterfs and can offer some insight to our issue.
