Has SeaweedFS been considered as a distributed storage alternative to Ceph? From what I’ve read, it’s both faster and easier to manage.
It’s not really an alternative to Ceph, it’s an alternative to Ceph-FS and Ceph-Object.
This means that an Incus storage driver for SeaweedFS would not be able to hold actual instances, but just storage volumes and storage buckets.
That’s still valuable on its own, but the main benefit of Ceph is the RBD support which allows for instances themselves to be picked up from anywhere in the cluster.
