Hi all, I'm taking a stab at deploying a storage cluster to explore the Halo AFR feature and running into some trouble. In GCE, I have 4 instances, each with one 10gb brick. 2 instances are in the US and the other 2 are in Asia (with the hope that it will drive up latency sufficiently). The bricks make up a Replica-4 volume. Before I enable halo, I can mount to volume and r/w files.
The issue is when I set the `cluster.halo-enabled yes`, I can no longer write to the volume: [root@jcope-rhs-g2fn vol]# touch /mnt/vol/test1 touch: setting times of ‘test1’: Read-only file system This can be fixed by turning halo off again. While halo is enabled and writes return the above message, the mount still shows it to be r/w: [root@jcope-rhs-g2fn vol]# mount gce-node1:gv0 on /mnt/vol type fuse.glusterfs (rw,relatime,user_id=0,group_id=0,default_permissions,allow_other,max_read=131072) Thanks in advace, -Jon Setup info CentOS Linux release 7.4.1708 (Core) 4 GCE Instances (2 US, 2 Asia) 1 10gb
