HA Zerofs

[wezell]

What does ZeroFS HA look like? How could this replace EFS in a Kubernetes cluster?

I'd like to run ZeroFS as a docker image in cluster and have my service pods mount via NFS but what happens when the single ZeroFS pod goes down? Can multiple ZeroFS instances connect to the same S3 backend? Would it work if you had zerofs_nfs_pod_0 and zerofs_nfs_pod_1 and just mounted the disk on the service pods via the service name? I am guessing there would be latency on the reads and possibly contention on writes but would it mostly work from a file storage perspective?

Another way to go would be to add ZeroFS to all the service pods and connect all of them to the same s3 bucket - if that works? Any limitations that you are aware of?

And thanks in advance, very cool tech.
